Dell E2016HV no power.

Hi, I want to ask about the mosfet value of this power supply. The mosfet is blown. The psu model is ILPI-354 V.A. Need urgently. Thanks.

Pictures of the MOSFET and of the P/S would help with answering your question.

I’m sorry for not include photo yesterday. Now i’m will give you the pictures. Thank you.

Probably something like a N-Channel TO-220 full pack 600V something or other. Match something up and stick it in its place. Forgot to mention... inspect the gate drive circuit of that mosfet too... if there is something wrong with it, it will blow the new one.

Oh I see, I already found the broken piece of the mosfet. It wrote JCS4N65MF. Search it online and no hope. I tell my boss, and they told me to stop repair those monitor because they want to scrap it. If I want to replace the mosfet, did I need to search for other mosfet that same with these mosfet datasheet? Thanks for the reply.

Good you found the lid to the MOSFET! All you need to know from JCS4N65MF: The FET here is a 4N65, 4A, 650V. Now do an online search and buy a replacement 4N65 or 4n80 or a 5N80. You need to have at least same spec MOSFET in here, but you can put let’s say a size or two bigger in there. Let’s say you got a 6n80 you can jam that in. But don’t get the idea to replace a 4n60 with a 12n60. It does work as long there is no problem with the PSU. So for testing purposes it’s o.k, but I wouldn’t leave it in there.
Again you don’t need exact the same MOSFET to replace the old one, you just need the same basic configuration…

replace the ceramic cap next to it with a 2kV rated version
