I've found this MOSFET-shaped component inside a Dell laptop power supply (I've lost the case so I can't tell you any details, sorry):
The problem is that I can't find any datasheet for it anywhere.
I will try and describe it in terms of the lines of text on the front:
- Line 1: C6312
- Line 2: A picture of two diodes facing each other.
- Line 3: 004
For the most part, it looks exactly like a MOSFET, metal back etc, and it is also mounted on a heat sink if that is useful.
Through some research I think I've narrowed it down to a Schottky barrier rectifier stack based on the symbol of the two diodes facing each other.
This isn't super serious or urgent, but I'm really interested to know what it is!
