# Toshiba T1200XE PSU repair. Identifying some SMD component 222/22Y

Need help. I'm trying to recover an old Toshiba T1200XE laptop and it seems the onboard PSU has a problem. One SMD looks damaged and I think it's better to replace it. I'm pretty sure this happened because old capacitors have leaked and electrolyte leaked to the board which provoked a short circuit. Sign on SMD looks like 222 where first digit underlined and second overlined. PSU board ID: 36M743776G. Size of this SMD 3 x 1.6 mm. Picture of it on board:

p.s. similar topic here

In the Google I've found another picture of this SMD and there different sign 22Y

Please help to identify this SMD and find some analogue of that SMD to replace it. Thank you!

This site says 22Y is a 22 volt Zener diode, and here's a datasheet that includes 22 volt Zeners having marking codes of 22, 22X, 22Y, and 22Z.
