This is just an additional idea to some of effective ideas given by famous administrator of this website like Sir Jestine Yong. I have not yet read this kind of technique. But I had been practicing this for a long time and found to be fast and effective.
2 Methods For Testing MOSFETS
First look up the part number for the MOSFET you want to test online and acquire the datasheet. Once you have the datasheet or have somehow gotten the specifications for the MOSFET you are testing and you know the pin configuration, set your analogue meter to the x10k range to check the MOSFET. Let’s say you are testing an N channel MOSFET, put the black test lead on the drain pin then touch the gate pin with the red test lead. This will discharge the MOSFETs internal capacitance. Next place the red test lead to the source pin while still holding the black test lead to the drain pin.
