How do you test a mosfet
Webthe Power MOSFET, a low repetition rate should be used. For tests involving a slow transition through the linear region, a damping resistor of at least 10 should be connected … WebJul 25, 2013 · 4. First you have to realize that a MOSFET is a 4 terminal device, Source, Drain, Gate and Body/Bulk. Here is a very simplified cross section of a NMOS transistor: Notice this picture that the Source and the drain are indicated by S/D. That is because which one is which is determined by operation/connection.
