What is Power MOSFET?
A MOSFET built to handle large currents and voltages. It switches quickly and is widely used in power supply circuits and the like.
Field: Power semiconductors
Power MOSFET in the explanations
In a power MOSFET, the p-type body tied to the source forms a pn junction with the n-type drift region, creating a parasitic diode that conducts from source to drain—the body diode.
