The power MOSFET is the most common type of field-effect transistor (FET). They act as electrical switches and amplifiers controlling the amount of electricity that can flow between the source and drain terminals based on the voltage applied to the gate terminal. With the help of its easy drive and high switching characteristics, engineers are possible to reduce product size and weight, while increasing efficiency at the same time.

Power MOSFETs are commonly used in a wide range of applications, including power supplies, DC/DC converters, motor drives, consumer electronics and automotive electronics.
