Test mosfets

(1/2) > >>

How do I test one. I only have a multi test and other simple stuff? I think when I was unsoldering them I burned them.


first hit on google search

no diode test range available. will it work with 9 volts?
I bet it's dead since I touched up on them, and unsoldering them with took some time with a 150w gun.

How do I know if it's a voltage regulator or mosfet. I looked at pics and they look similar.

MOSFETs are pretty heat sensitive. If you didn't heat sink it, you might have fried it. 

You should be able to tell it's a mosfet or a voltage regulator by the part number. Just type the part number into digikey and see what comes up.
