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
