Ive 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! Thanks.
