WebWhat Is a MOSFET? Metal Oxide Silicon Field Effect Transistors commonly known as MOSFETs are electronic devices used to switch or amplify voltages in circuits. It is a … WebDefinition. Metal-oxide semiconductor field-effect transistor; metal-oxide silicon field-effect transmitter. In a MOSFET, the conductive channel between the drain and source contacts is controlled by a metal gate separated from the channel by a very thin insulating layer of oxide. The gate voltage establishes a field that allows or blocks ...
WebOct 7, 2013 · How to Use MOSFET as a Switch. To use a MOSFET as a switch, you need to ensure that the gate-source voltage (Vgs) is higher than the source voltage. When the gate is connected to the source (Vgs=0), the MOSFET remains off. Take the IRFZ44N, a “standard” MOSFET, as an example.
