AO6804A Introduction

According to the carrier of the conduction channel, it can be divided into N channel and P channel. Assuming that the carriers of the conductive channel are electrons, it is called an N-channel; assuming that the carriers are holes, it is called a P-channel. A MOS tube is a semiconductor device in which unipolar carriers participate in conduction.

The core of power semiconductors is the PN junction. From diodes, triodes to field effect transistors, various applications are made according to the characteristics of the PN junction. According to whether the inversion layer exists in the case of no electricity, MOS tubes can be divided into enhancement type and depletion type. Field effect transistors are divided into junction type and insulated gate type, among which the insulated gate type is also called MOS tube (Metal Oxide Semiconductor).

MOS tube is a metal (Metal)-oxide (Oxide)-semiconductor (Semiconductor) field effect transistor, or metal-insulator (Insulator)-semiconductor. .

There are three parasitic capacitance parameters in the MOS tube specification, namely: input capacitance Ciss, output capacitance Coss, and reverse transfer capacitance Crss. What do the three capacitance parameters represent in the body of the tube? How did it form? .

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.
