MOSFET Package Switching Tube Selection and Circuit Diagrams
The first step is to make a selection of MOSFETs, which come in two main types: N-channel and P-channel. In power systems, MOSFETs can be thought of as electrical switches. When a positive voltage is added between the gate and source of...Read more -
Introduction to the working principle of commonly used high-power MOSFETs
Today on the commonly used high-power MOSFET to briefly introduce its working principle. See how it realizes its own work. Metal-Oxide-Semiconductor that is, Metal-Oxide-Semiconductor, exactly, this name describes the structure of the...Read more -
MOSFET overview
Power MOSFET is also divided into junction type and insulated gate type, but usually mainly refers to the insulated gate type MOSFET (Metal Oxide Semiconductor FET), referred to as power MOSFET (Power MOSFET). Junction type power field ...Read more -
MOSFET original basic knowledge and application
As for why depletion mode MOSFETs are not used, it is not recommended to get to the bottom of it. For these two enhancement-mode MOSFETs, NMOS is more commonly used. The reason is that the on-resistance is small and easy to manufacture....Read more -
What are the functions of MOSFET?
There are two major types of MOSFET: split junction type and insulated gate type. Junction MOSFET (JFET) is named because it has two PN junctions, and insulated gate MOSFET (JGFET) is named because the gate is completely insulated from ...Read more -
Explanation of each parameter of power MOSFETs
VDSS Maximum Drain-Source Voltage With the gate source shorted, the drain-source voltage rating (VDSS) is the maximum voltage that can be applied to the drain-source without avalanche breakdown. Depending on the temperature, the actual ...Read more -
