Hello.
I accidentally powered WD40EFPX with the 19V power brick.
With the help of this forum (thank you, @fzabkar) i was able to identify blown TVS diode (1) and fuse (2), but got a bit carried away with desoldering and damaged SOD-323 element with “AK” marking (3) - image attached.
I am planning to replace TVS diode with SMAJ13A, but cannot understand what can be used to replace “AK” diode.
Can anyone help with identifying this component? I see that same element used between 12V-gnd and 5V-gnd, so it cannot be a zener diode?
I believe “AK” is a Schottky rectifier. In any case, it doesn’t need to be replaced.
Thank you for reply. Unfortunately, i damaged this component while removing blown fuse, so i need to replace it as well. Is it necessary for the drive to work or it serves ESD/overvoltage protection?
It is a protection device. It is not necessary for normal operation.
Thank you.
I searched for schottky rectifiers in sod323 package and I believe this is PMEG3010EJ,115 diode 30V 1A.
