BYN31028Z_AO4840&Special 30V Guide

Xinjie, behind this FET NCE80H12, utilizes its own technical advantages to work closely with 8-inch wafer foundries, packaging and testing foundries, and has a complete quality management system to ensure continuous product quality and stable supply.

MOS tubes like NCE80H12 convert the DC power in the battery into AC power when the electric vehicle is running normally, thereby driving the motor to run.

Barrier capacitance: In power semiconductors, when the N-type and P-type semiconductors are combined, the electrons of the N-type semiconductor will partially diffuse into the holes of the P-type semiconductor due to the concentration difference, so they will form on both sides of the junction surface. Space charge area (the electric field formed by the space charge area will resist the diffusion movement, and finally make the diffusion movement reach equilibrium);

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. .

When the low UDS separate 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). Growth slows as the conduction channel approaches pinch off. Figure 1. Drain output characteristics of MOS transistors The output characteristics of field effect transistors can be divided into four regions: variable resistance region, cut-off region, breakdown region and constant current region. Variable resistance region (UDS In this region, ID increases linearly as UDS increases.

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. 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 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. The breakdown region is in the region of considerable drain-source voltage UDS, and the drain current is approximately constant.
