Hello,

Any suggestion where to look for WD pcb schematics?

I have a PCB 2060-701537-004 Rev.A (PCB Sticker: 2061-701537-Q00 AD) with a burn component identified on the picture below.

Does someone can help me to identify this component in order to replace it with a good one.

That might be a 12V TVS diode used to protect the hard drive in case of a over volt. Not sure though if its 5v though.

Normally snipping it off will make the drive work again, but should be replaced with the same type. The 0 ohm resister around the diodes act as fuses, so the one next to it might be blown too.

Better wait for confirmation before doing anything.

yes 12V TVS

It's actually a 13V diode, but a regular 12V diode will be OK. Both will have a minimum breakdown voltage in excess of 14V.

SMBJ13A, STMicroelectronics, marking BUF, 600W, 13V standoff voltage:

BTW, I suggest you flow a blob of solder over R64 for proper protection.
