i am testing a FET
here is spec sheet
http://forum.allaboutcircuits.com/attachment.php?attachmentid=17300&d=1268639919
now here is what one website says.
using the diode function on your DMM.
probe with - on the drain and + on the gate. this should arm the FET.
then keep - on drain and put + on source. multimeter should beep.
my FET passed this SO FAR.
now it says to test the FET's ability to switch off touch all three pins with finger. then put - on drain and + on source again and should get a high reading.
well my FET still beeps. is the FET defective????
