Doubts with a diode Lenovo A10-70 Tablet (A7600-F)

[Arkangelus]

Hi friends! I am trying to repair this tablet and I found that this zener diode (part number CDZ55C5V6S) has a hole in the middle (attached photos and schematic). I have searched on Aliexpress, to order that diode, and I can't find it.

My question is, will there be a replacement for this diode? And which diode could replace it that is similar to this?

Thank you very much in advance for reading my question

What is the part # reference in the schematic for this blown (holy?) part ?

Which connector is on the other side of this blown part ?

Never mind - datasheet is attached. Looks to be a 5v6 zener. Let me look around.

Thank you very much for answering. On the other side there are no more components and it is perfect. Nothing burnt. It's just that diode that has a big hole in it.

Ran out of time earlier...this is an 0805 smd size zener diode at 5v6 rating. Nothing special.

Select the 5v6 rated part.

oh man! You are very kind to help me with this. I'm a newbie who's been at this for a very short time and it's wonderful to find people like you willing to help. Eternally grateful for your time and disposition. Thank you very very much!!!

No worries. One extra comment is that the original part appears to be a 500mW rated part = 0.5W.

The one I have linked is 250mW rated = 0.25W.

Ask each vendor if they can supply in 0805 size, the 500mW part at 5v6. Certainly supply the original part # from the above datasheet. They should be able to find it.

Good luck!
