lenovo y700 Esd Protection Diode equivalent

[Dcdaniel]

Hello guys, i have an old lenovo y700 laptop that has a burned esd diode. I cannot find the Az5123 diode anywhere in my country and I am looking for a replacement or something equivalent if is available. I attach the documentation of the diode and where in the schematic it is needed. If more details are needed I can offer them.Thank you!

This is a very common part. From where do you wish to buy the part?

Digikey? Mouser? Arrow?

Do you have vat #?

If yes, may be able to ship it to you for free. These are very low cost parts.

Technically, the ESD diode is not required but it does serve a purpose to clamp any voltage (transient) surges that may cause further damage. So in short, it is a good idea to have the ESD device in place. We build products for the CNC & industrial markets and know that our competitors do not have such protection to lower their costs and their widgets often die out in the field. Our designs feature multiple layers of protection. We have zero failures. Better for both parties.

Another option is to use a Semtech UCLAMP3311P.TCT https://www.elvikom.pl/lenovo-l340-g...nt-t66308.html

Any bidirectional TVS in the same DFN1006 package and with the same ratings will do.
