what is mos tube

The mos tube is a metal-oxide-semiconductor field effect transistor, or a metal-insulator-semiconductor. The source and drain of the MOS tube can be reversed, and they are all N-type regions formed in the P-type backgate. In most cases, these two regions are the same, even if the two ends are reversed, it will not affect the performance of the device. Such devices are considered symmetrical.

The bipolar transistor amplifies the small change of the current at the input end and outputs a large current change at the output end. The gain of a bipolar transistor is defined as the ratio of output to input current (beta). Another type of transistor, called a field effect transistor (FET), converts changes in input voltage into changes in output current. The gain of a FET is equal to its transconductance, defined as the ratio of the change in output current to the change in input voltage. The most common ones on the market are N-channel and P-channel. For details, refer to the picture on the right (N-channel depletion MOS transistor). The common P-channel is a low-voltage MOS tube.

FETs affect the current flowing through the transistor by projecting an electric field on an insulating layer. In fact no current flows through this insulator, so the gate current of the FET is very small. Ordinary FETs use a thin layer of silicon dioxide as the insulator under the GATE. Such transistors are called metal-oxide-semiconductor (MOS) transistors, or, metal-oxide-semiconductor field effect transistors (MOSFETs). Because MOS tubes are smaller and more power efficient, they have replaced bipolar transistors in many applications.

Advantages of mos tube

1. Can be applied to magnification. Since the input impedance of the FET amplifier is high, the coupling capacitor can be small, and the electrolytic capacitor is not necessary.

2. The high input impedance is very suitable for impedance transformation. It is often used in the input stage of multi-stage amplifier for impedance transformation.

3. Can be used as a variable resistor.

4. Can be easily used as a constant current source.

5. Can be used as an electronic switch.

6. Great flexibility in circuit design. The gate bias voltage can be positive, negative or zero, the triode can only work under the forward bias, and the electron tube can only work under the negative bias. In addition, the input impedance is high, which can reduce the load of the signal source and is easy to match with the previous stage.

MOS tube type and structure

MOSFET is a type of FET (the other is JFET), which can be made into enhancement mode or depletion mode, P-channel or N-channel, a total of 4 types, but only the enhancement-mode N-channel MOS is actually used. Tube model and enhanced P-channel MOS tube model, so NMOS is usually mentioned, or PMOS refers to these two. As for why not to use depletion-type MOS tubes, it is not recommended to get to the bottom of it. For these two enhanced MOS tubes, NMOS is more commonly used. The reason is that the on-resistance is small and it is easy to manufacture. Therefore, in the application of switching power supply and motor drive, NMOS is generally used. In the following introduction, NMOS is mainly used. There is parasitic capacitance between the three pins of the MOS tube, which is not what we need, but is caused by the limitation of the manufacturing process. The existence of parasitic capacitance makes it more troublesome to design or select the driving circuit, but there is no way to avoid it, which will be described in detail later. It can be seen on the schematic diagram of the MOS tube that there is a parasitic diode between the drain and the source. This is called the body diode, and this diode is very important when driving inductive loads. By the way, the body diode only exists in a single MOS transistor, and usually does not exist inside the integrated circuit chip.

Choosing a correct MOS tube can control the manufacturing cost well. It is important to match the product with an appropriate component, which will give full play to its "screw" in the future use of the product. ” to ensure that the device has a stable and lasting application effect. So in the face of the dazzling array of MOS tubes on the market, how to choose? Next, we will explain the selection requirements of MOS tubes in 7 steps.

MOS tube is the basic component of electronic manufacturing, but when faced with different packages, different characteristics, and different MOS tubes, how to choose? Is there a worry-free and labor-saving selection method?

The first is to determine the selection of N and P channels

There are two types of MOS tubes, namely N-channel type and P-channel type. The structures are different, and the voltage polarity used will also be different. Therefore, before deciding which product to choose, it is necessary to first determine the use of N-channel. Or a P-channel MOS tube.

MOS tube selection skills

Two structures of MOS tubes: N-channel type and P-channel type

In a typical power application, when a MOS transistor is grounded and the load is connected to the mains voltage, the MOS transistor constitutes a low-side switch. In the low-side switch, an N-channel MOS transistor should be used because of the voltage required to turn off or turn on the device.

When the MOS tube is connected to the bus and the load is grounded, a high-side switch is used. Usually, a P-channel MOS transistor is used in this topology, which is also due to the consideration of voltage driving.

To select the right device for an application, it is necessary to determine the voltage required to drive the device and a method that can be easily implemented in the design.

The second step is to determine the voltage

The higher the voltage rating, the higher the cost of the device. From a cost perspective, it is also necessary to determine the required voltage rating, that is, the maximum voltage that the device can withstand. According to practical experience, the rated voltage should be greater than the mains voltage or bus voltage, and generally leave a voltage margin of 1.2 to 1.5 times, so as to provide sufficient protection so that the MOS tube will not fail.

As far as the selection of MOS tubes is concerned, it is necessary to determine the large voltage that may be borne between the drain and the source, that is, a large VDS. Since the large voltage that the MOS tube can withstand varies with temperature, the designer must test the voltage variation range over the entire operating temperature range. The rated voltage must have sufficient margin to cover this variation and ensure that the circuit does not fail.

In addition, design engineers also need to consider other safety factors: such as voltage transients induced by switching electronics (often with motors or transformers). In addition, the rated voltage of different applications is also different; usually portable devices use 20V MOS tubes, FPGA power supplies are 20-30V MOS tubes, and MOS tube VDS is 450-600V for 85-220V AC applications.

The third step is to determine the current

After the voltage is determined, the next thing to determine is the current of the MOS tube. It needs to be determined according to the circuit structure. The rated current of the MOS tube should be a large current that the load can withstand under all conditions; similar to the case of voltage, the rated current of the MOS tube must meet the needs of the system when the peak current is generated. The determination of the current needs to start from two aspects: continuous mode and pulse spike. In the continuous conduction mode, the MOS tube is in a steady state, and the current continuously flows through the device at this time. A pulse spike is when there is a large surge (or peak current) flowing through the device. Once the high current under these conditions is determined, it is simply a matter of choosing a device that can handle this high current.

After selecting the rated current, the conduction loss must also be calculated. In practice, the MOS tube is not an ideal device, because there will be power loss during the conduction process, that is, conduction loss. The MOS tube is like a variable resistor when it is "on", which is determined by the on-resistance RDS(ON) of the device and varies significantly with temperature. The power loss of the device is calculated as PTRON=Iload2×RDS(ON) (Iload: large DC output current). Since the on-resistance will change with temperature, the power loss will also change proportionally. The higher the voltage VGS applied to the MOS tube, the smaller the RDS(ON); otherwise the RDS(ON) will be higher.

For the system designer, this requires a trade-off. For portable designs, a lower voltage can be used (more common); for industrial designs, a higher voltage can be used. Note that the RDS(ON) resistance will rise slightly with current.

Technology has a significant impact on device characteristics, as some technologies tend to increase RDS(ON) when increasing large VDS (drain-source voltage rating). For such a technology, if the VDS and RDS(ON) are to be reduced, then the die size must be increased, thereby increasing the package size and associated development costs associated with it. Several techniques exist in the industry to try to control the increase in wafer size, chief among which are channel and charge balancing techniques.

The fourth step is to determine the thermal requirements

After determining the current, it is necessary to calculate the cooling requirements of the system. Designers must consider two different scenarios: bad and real. It is recommended to use the calculation result for the bad case, because this result provides a larger safety margin to ensure that the system does not fail. There are also some measurement data that need attention on the MOS tube data sheet, such as the thermal resistance between the semiconductor junction of the packaged device and the environment, and the large junction temperature.

The junction temperature of the device is equal to the maximum ambient temperature plus the product of thermal resistance and power dissipation, that is, junction temperature = maximum ambient temperature + (thermal resistance × power dissipation). According to this equation, the high power dissipation of the system can be solved=I2×RDS(ON).

Since the designer has determined the large current that will pass through the device, the RDS(ON) at different temperatures can be calculated. It is worth noting that when dealing with simple thermal models, the designer must also consider the thermal capacity of the semiconductor junction/device case and case/environment; that is, the requirement that the printed circuit board and package do not heat up immediately.

Avalanche breakdown (meaning that the reverse voltage on a semiconductor device exceeds a large value and forms a strong electric field that increases the current in the device) will dissipate power, increase the temperature of the device, and possibly damage the device. Semiconductor companies perform avalanche tests on their devices, calculate their avalanche voltages, or test the robustness of the devices.

There are two methods for calculating the rated avalanche voltage; one is statistical method and the other is thermal calculation. Thermal calculations are widely used because they are more practical. In addition to computing, technology also plays a big role in the avalanche effect. For example, an increase in die size increases avalanche resistance and ultimately improves device robustness. For the end user, this means a larger package in the system.

The fifth step is to determine the switch performance

The next step in selecting a MOS tube is to determine its switching performance. There are many parameters that affect switching performance, but the important ones are gate/drain, gate/source, and drain/source capacitance. Because these capacitors must be charged each time they switch, switching losses will be generated in the device; the switching speed of the MOS tube is also reduced, and the device efficiency is also reduced; among them, the gate charge (Qgd) affects the switching performance. big.

In order to calculate the total loss of the device during the switching process, the designer must calculate the loss during the turn-on process (Eon) and the loss during the turn-off process (Eoff), and then deduce the total power of the MOS transistor switch: Psw=(Eon+Eoff)×switch frequency.

The sixth step is to consider the packaging factor

Different package sizes of MOS tubes have different thermal resistance and power dissipation, and the heat dissipation conditions and ambient temperature of the system need to be considered (such as whether there is air cooling, the shape and size of the heat sink, and whether the environment is closed or not). The basic principle is On the premise of ensuring the temperature rise of the power MOS tube and the system efficiency, a power MOS tube with more general parameters and packaging is selected.

Common MOS tube packages are:

①Plug-in package: TO-3P, TO-247, TO-220, TO-220F, TO-251, TO-92;

②Surface mount type: TO-263, TO-252, SOP-8, SOT-23, DFN5*6, DFN3*3;

TO package MOS tube

Different packaging forms, the corresponding limit current, voltage and heat dissipation effect of MOS tube will be different, a brief introduction is as follows.

TO-3P/247: It is a commonly used packaging form for medium and high voltage and high current MOS tubes. The product has the characteristics of high withstand voltage and strong breakdown resistance, and is suitable for medium voltage and high current (current above 10A, withstand voltage below 100V) Use in places with a withstand voltage of 120A or more and a withstand voltage of 200V or more.

TO-220/220F: The MOS tubes of these two package styles are similar in appearance and can be used interchangeably. However, the TO-220 has a heat sink on the back, and its heat dissipation effect is better than that of the TO-220F, and the price is relatively expensive. These two packaged products are suitable for applications with medium voltage and high current below 120A and high voltage and high current below 20A.

TO-251: This package product is mainly used to reduce the cost and reduce the product volume, and is mainly used in the environment of medium voltage and high current below 60A and high voltage below 7N.

TO-92: Only low-voltage MOS tubes (current below 10A, withstand voltage below 60V) and high-voltage 1N60/65 are used in this package, mainly to reduce costs.

TO-263: It is a variant of TO-220. It is mainly designed to improve production efficiency and heat dissipation. It supports extremely high current and voltage. It is more common in medium-voltage and high-current MOS tubes below 150A and above 30V.

TO-252: It is one of the current mainstream packages, suitable for environments where high voltage is below 7N and medium voltage is below 70A.

SOP-8: This package is also designed to reduce costs. Generally, it is more common in medium-voltage MOS tubes below 50A and low-voltage MOS tubes around 60V.

SOT-23: It is suitable for use in the environment of several A current and 60V and below voltage. It is divided into two types: large volume and small volume. The main difference is that the current value is different.

The working principle of MOS tube (with N-channel enhancement mode MOS field effect tube) is to use VGS to control the amount of "induced charges" to change the condition of the conductive channel formed by these "induced charges", and then to control the leakage. purpose of polar current. During the manufacture of the tube, a large number of positive ions appear in the insulating layer through the process, so more negative charges can be induced on the other side of the interface. These negative charges connect the N region of the hypertonic impurities and form a conductive channel channel, there is a large drain current ID even when VGS=0. When the gate voltage changes, the amount of charges induced in the channel also changes, and the width of the conductive channel also changes, so the drain current ID changes with the gate voltage.

The mos tube is a metal-oxide-semiconductor field effect transistor, or a metal-insulator-semiconductor. The source and drain of the MOS tube can be reversed, and they are all N-type regions formed in the P-type backgate. In most cases, these two regions are the same, even if the two ends are reversed, it will not affect the performance of the device. Such devices are considered symmetrical.
