Power MOSFET - Wikipedia
A power MOSFET is a specific type of metal–oxide–semiconductor field-effect transistor (MOSFET) designed to handle significant power levels. Compared to the other power semiconductor devices, such as an insulated-gate bipolar transistor (IGBT) or a thyristor, its main advantages are high switching speed and good efficiency at low voltages.

A Power Metal-Oxide-Semiconductor Field-Effect Transistor (Power MOSFET) is a type of semiconductor device widely used in electronic circuits for switching and amplification of electrical signals, particularly in high-power applications.
Power MOSFETs, on the other hand, are majority carrier devices with no minority carrier injection. They are superior to the BJTs in high frequency applications where switching power losses are important. Plus, they can withstand simultaneous application of high current and voltage without undergoing destructive failure due to second breakdown.
2006年3月2日 · Power MOSFETs are well known for superior switching speed, and they require very little gate drive power because of the insulated gate. In these respects, power MOSFETs approach the characteristics of an “ideal switch”. The main drawback is on-resistance RDS(on) and its strong positive temperature coefficient.
