BYS326_P1503HV Introduction

In response to this demand, Xinjie can produce N-channel trench process MOS transistors with small internal resistance and good overcurrent resistance - NCE80H12, the on-resistance of NCE80H12 is less than 6mΩ, the output current can reach 120A, and the motor torque is better , .

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. According to the carrier of the conduction channel, it can be divided into N channel and P channel. A MOS tube is a semiconductor device in which unipolar carriers participate in conduction.

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.

However, in terms of structure, there is a big difference between them. In order to better understand the mechanism of power MOSFET, we must first recall the mechanism of low-power FET. . The following describes the principle of the MOS transistor with the structure of an N-channel enhancement type low-power MOSFET. Working principle of power MOS tube Power MOS tube is developed from low-power MOS tube.

Diffusion capacitance: When a forward voltage is applied, the non-equilibrium minority carrier concentration near the interface of the depletion layer is high, far from the non-equilibrium minority carrier concentration is low, and the concentration gradually decays from high to 0 until 0. The process of charge accumulation and release in this phenomenon is the same as that of capacitor charging and discharging, which is called diffusion capacitance. When the applied forward voltage increases, the concentration of unbalanced minority carriers increases and the concentration gradient also increases, and when the applied voltage decreases, the change is opposite.

The parasitic capacitance structure of the MOS tube is as follows. Among them, the width of polysilicon, the width of the channel and the trench, the thickness of the G oxide layer, and the doping profile of the PN junction are all factors that affect the parasitic capacitance. .
