Good evening. I have a MOSFET that is marked as a PH4847 and is used in an automotive application. I believe it to be a 15A, 60V N-Channel MOSFET TO-220 similar to an IRFZ44N.
When I test this MOSFET with my DCA55, it seems to test okay. When I do it with a DVOM, it turns on and off okay but if I short the leads, I am still seeing a 2.9V reading on my meter with my red lead placed on the drain, and the black lead on the source. Everything else seems to read okay.
Is this a problem? If not, what am I looking at. Thank you in advance.
Also, if anyone has any clue as to what the PH4847 is, appreciate that as well.
