How to Measure the Health of a MOSFET with a Multimeter
Use the unidirectional conduction characteristics of the parasitic diode inside the MOSFET to determine its health. Step 1: Short-Circuit the Three Pins for Discharge The purpose of this step is to discharge the parasitic capacitance inside the MOSFET to prevent any voltage difference, which could cause erroneous measurements. Step 2: Measure the Internal Diode Set … Read more
