I have this N-Channel mosfet I'm checking using a DVM. Mosfet is a FQP50N06 When I charge the gate with 9VDC [spec. is +- 25V] Then check from the drain to source the ohms reading is 5 ohms for only 3 milliseconds. then goes back up to 28meg. indicating the gate is opening. My question is: Shouldn't the gate stay closed until the gate is shorted to the drain or grounded? Internal Diode checks ok.
