BYN664_AP9960AGM Introduction

Today I will introduce to you a domestic FET that is suitable for lithium battery protection boards and can replace MOS tubes such as AO3401: NCE3401.

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 , .

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 N-channel enhancement mode MOS transistor uses a low-doped P-type semiconductor as the substrate, and forms two heavily doped N+ regions on the substrate by a dispersed method, and then generates a very thin one on the P-type semiconductor. A silicon dioxide insulating layer, and then photolithography is used to etch away the silicon dioxide layer on the upper end of the two heavily doped N+ regions, exposing the N+ regions, and finally on the outer surface of the two N+ regions and the two between them. The surface of silicon oxide is sprayed with a layer of metal film by evaporation or sputtering. These three metal films constitute the three electrodes of the MOS tube, which are called source (S), gate (G) and drain (D) respectively. .
