NCE5080CK_NCEP60ND60G Introduction

Their various switching actions are almost the same. Of course, when they burn out, there must be a small tube that can't bear it first. So the stability of the tube is inseparable from the manufacturing process, and poor workmanship may result in the inconsistency of the parameters of these small tubes.

In addition to the above-mentioned NCE80H12 suitable for electric vehicle controllers, Nanshan Electronics also provides Fenghua resistance-capacitance sense, long-crystal MOS transistors, Epson active and passive crystal oscillators, etc.

The conductive channel of the MOS tube can be formed during the production process or by turning on an external power supply. When the gate voltage is equal to zero, there is a channel (that is, formed during production), which is called depletion mode. When an external voltage is applied The one that forms the channel later is called the enhancement type. .

. For these two enhanced MOS tubes, NMOS is more commonly used. As for why not to use depletion-type MOS tubes, it is not recommended to get to the bottom of it.

For 17 months without the light of day, Zandman's uncle taught him algebra, trigonometry, geometry and physics. It can be said that what Zandman learned during those darker days laid the groundwork for him to start Vishay. After the war, Zandman immigrated to France, earning degrees in Mechanical Engineering, Applied Mechanics and General Physics, and a Ph.D. in Mechanical Physics at the Sorbonne University in Paris. Zandman was born in Poland in 1928. During the Nazi Holocaust in World War II, Zandman was taken in by an old housekeeper whom Zandman's grandmother had rescued. He and four others hid under the housekeeper's floor for 17 months before they were able to escape the Holocaust. . In 1956, Zandman immigrated to the United States and founded Vishay in 1962. .

Power MOSFETs are used in power conversions such as switching power supplies and inverters, and they work in two regions, the cut-off region and the breakdown region. The breakdown region is in the region of considerable drain-source voltage UDS, and the drain current is approximately constant. . When the UDS increases to a certain value, the drain PN junction breaks down, the leakage current increases rapidly, and the curve turns upward and enters the breakdown region. The full area (UDS>UGS-UT) guarded in the above three areas is the full area, also known as the constant current area or the amplification area.

Variable resistance area (UDS In this area, when UDS increases, ID increases linearly. When the low UDS splitting and pinch-off voltage is large, the MOS tube is equivalent to a resistance, and this resistance decreases with the increase of UGS. Cut-off area (UGS). When the conductive channel is close to the pinch off, the growth slows down. Figure MOS tube drain output characteristics The output characteristics of field effect transistors can be divided into four regions: variable resistance region, cut-off region, breakdown region and constant current zone.

On the one hand, the three electrodes of the low-power MOSFET are on one plane, the channel cannot be made very short, and the channel resistance is large. On the other hand, the conductive channel is composed of surface induced charges, and the channel current is the surface current. To increase the current capacity, it is necessary to increase the chip area. Such a structure is unlikely to achieve a large current. . The structure of the MOSFET shown in the figure is not suitable for use in high-power applications for two reasons.
