BYJ6318_9960AGM Introduction

In addition to the above-mentioned NCE80H12 suitable for electric vehicle controllers, Nanshan Electronics also provides Fenghua resistance-capacitance sense, long-crystal MOS transistors, Epson active and passive crystal oscillators, etc.

When naming the company, the founders incorporated their nostalgia for the past and expectations for the future. A simple name with many untold stories behind it... . There are many well-known brands in the electronics industry, each brand is like a person's name, and its origin and naming have its own unique style. Their success today is due to the founders.

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);

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.

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.

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. .
