Title: Pc Engine Super CDROM2 - ZD301 issue
Post by: Carlito on 02/03/2026, 03:10 AM
Hello,
I am trying to fix some PC Engine console and I recently got stuck with a Super CDROM2.
The Caps leaked so much that the liquid corroded part of the PCB.
I tried to gently clean it but several components unsoldered during the process. (not mentioning that I have to create some bridges to repair some damages)
Q304
ZD301
ZD302
I cleaned them and tried to put them again since they seemed fine.
However for ZD301, corrosion removed one of the legs.
I would like to buy a new part but I was not able to find any information regarding the value I should get for it.
I tried with a different Super CDROM2 and I measured a value of 10.78V which seems a little high (I was expecting something around 5V)
Do you know where I can get some data sheet regarding this type of part?
Or perhaps somebody can measure the value on their device so I can get a better understanding what I shall buy?
Thank you for your help.
