In this video, I have explained some methods of checking MOSFET transistor using a multi-meter. The method is shown here for testing MOSFET is very easy. Here have used Enhancement N-channel MOSFETs (IRF832 and IRFP250N) to explain how to test MOSFET. I have also explained How to identify the 3 terminals (Gate, Drain & Source) of MOSFET. 1st method: In the first method, after you have identified the Gate, Drain & Source terminals of MOSFET, you can check the MOSFET in off state by connecting the black lead to the source terminal and red lead to drain terminal in diode testing mode. You should not get continuity between the source and drain at off state for Good MOSFET. Then you have to charge the gate terminal and check the MOSFET at ON-state. 2nd method: In the second method, we will check the MOSFET with the help of a simple circuit. I this method we will turn on and turn off the MOSFET and also control the Drain to source current by varyin …...more
