Electronic – Need help identifying a thestery component with double-diode marking

diodesidentificationpower supplyrectifierschottky

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!

I think you are on the right track, but the 12 in the part number is a red herring, IMO. Probably a date-code.

After a bit of detective work, the most likely candidate I found was this ESAC63-004 common cathode Schottky diode array:

From what you say, it could be the rectifier of the output of the power supply, as can be seen in an image of a DELL power supply found here (emphasis on the image is mine):

EDIT

Another datasheet for the same part can be definitive (yellow highlighting is mine):
