Mosfet is an electronic component, which is defined as a metal oxide semiconductor field-effect transistor. These mosfet's are mainly used in the low voltages to generate high efficiency or output. This is an advanced component compare to the IGBT, Thyristors and it generate high commutation speed at low voltages also.
Mosfet has a wide range of applications, which is used in switching or amplifying electronic signals. These are easily integrated into digital and analog circuit. Mosfet is used in mobiles, CPU, TV's, Music system, refrigerator, etc.
