Re: smd diode identify

what motherboard is this on

it is on NOKIA c2 (TA-1204)... locate near battery pin.

thank you for your time..
but the diode have 2 pads under, not have legs. any suggestions?

Re: NOKIA c2 TA-1204 smd diode identify

Find a SMD zener diode that looks like what you have -> review the voltage to match what was discovered by @SMDFlea.

It will help to use micrometers to measure the dimensions of the damaged part.

Summary: it is a SMD zener diode but the final physical dimensions will have to come from your side so you can drop and replace onto the PCB pads of your logic board.
