WebSep 8, 2009 · FET s are checked by measuring different resistances by a multimeter. When resistance is checked between source and drain, it should be of the order of 10 kohms. How to test a JFET ? JFET testing methods. When a JFET is checked as a diode (gate-to-channel junction) multimeter should indicate low resistance between gate and source with one … WebApr 11, 2024 · Test for proper functioning: Apply a voltage to the MOSFET gate and measure the voltage between the source and drain. When the MOSFET is active, its voltage level will nearly reach your power supply maximum. Conversely, when it's inactive, you should expect zero volts to remain in effect. Test for gate leakage: Apply a voltage to the MOSFET ...
