NCE40H32VD_NCEP60T12AK 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.

The smaller the internal resistance, the larger the current (because the heat is small). The resistance of this current path is called the internal resistance of the MOS tube, that is, the on-resistance. The size of this internal resistance basically determines how much on-current the MOS tube chip can withstand (of course, it is related to other factors, such as thermal resistance).

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. .

. 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.

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.

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.
