What is a Power MOSFET?
Before we delve into the specifics of the STF120NF10, let's first understand what a power MOSFET is and how it works.
A power MOSFET (metal-oxide-semiconductor field-effect transistor) is a type of transistor that is used to switch and amplify electrical signals. MOSFETs have become increasingly popular in electronic circuits because of their high efficiency, low power consumption, and high voltage tolerance.
In essence, MOSFETs work by controlling the flow of current between the drain and source terminals using an electric field created by the voltage applied to the gate terminal.
