İ search this diode, does anyone know this?
When İ search D1ꓷ result nothing.
When İ search D1 multiple result zener,pin,4148 etc.
İf Anyone know this diode ,please share information,
Have a nice day and thanks for ur interest.

The silk screen symbol for D9 right next to D1 looks like a TVS symbol:

I wonder D1 is a TVS as well. If so, you'll need to figure out why you're getting voltage spikes large enough to blow out your TVS diode before you replace it.

Also there's a pretty good chance that whatever damaged that part also damaged other parts on the board, so you may have a bigger repair job then you think!

@ebeowulf17 I know the reason, thank you very much for your advice, I used a different brand psu cable on my computer because I did not measure the error of my own pin to pin structures should not be able to think.
This type of diodes in my country very rarely encountered elements in my life, the second time I'm encountering the first two years I did not use the computer psu burned for no reason this second, I actually thought to prevent reverse voltage diode or regulated purpose zener this piece. Anyway now I'll have to find a suitable TVs for this circuit, @ebeowulf17 @Dodgydave thank you for your attention and your time. I think these TVs will cause more trouble for me. :D
