Hello everyone, this is my first post in the forum so i would like to use the opportunity to thank Dave for his fantastic job... I've learned so much thanks to his videos, very inspirational !
This being said, let's get to the point. I'm trying to repair a friend's car audio system which have been blown up by trying to jump start the car with reverse polarity... I guess it must be a diode or something but unfortunately i can't find any info from the markings. I can clearly identify the ST logo but i haven't been able to find a reference. Here is what i think i read :
ST E
MFP
C451
Pictures attached in case of i'm missing something.
The car audio system is a Siemens VDO brand CD 70 NAVI for Opel/Vauxhall Astra H.
The component fails short and blows the fuse each time power is applied to the unit.
Thanks for your help.

Well... that was fast... that was accurate... and it could have taken years to find this myself !
Thanks a lot Richard, I will keep you posted with the results !

I just went to the ST Micro website and pasted MFP into the search box.
It could have been a lot worse.
I wish there were some comprehensive and authoritative central source for cryptic SMD labels. :-\

This, but not as comprehensive as one might want.
