SMD diode identification

09-23-2022, 08:32 AM

I have to replace the surface mount diodes in the attached picture, because they are open, so I need help in identifying them. The marking on the printed circuit board starts with the letters CR, the markings on the diodes are NM 64 A. The dimensions of the diodes are 3.5 x 5.5 millimeters. Which one should I order as replacements?

Please help me identify this zener diode.
I find it hard to see the datasheet. The diode was found on 14TB 3.5" WD HDD

I'm looking into having it replaced.

Pictures attached...

Diode identification for data rescue

by MrBojangles

Heyo

I'm trying to perform data rescue on this drive and don't want to make a mistake. I've found a burned diode and a shorted capacitor right next to it. I've found a component on eBay that seems to match up. Can someone confirm please? Also I don't mind replacing it with a compatible component if it's easy to get hold of.

Have a nice day

OMRON E5CS heater controller Diode identification help

by lethbrp

Hi everyone,

I have a diode that I need help identifying. I've been scouring the web (newbie) can can't seem to find anything. Perhaps I'm looking in the wrong place. Attached is an image of the diode. If you could help me it would be greatly appreciated. Also, an explanation of how to calculate the values would be great.

Thanks for your help.

Peter...

Diode Identification marked "DK"

by CraigR

I am not sure if this is the right place to post this but I need help identifying a surface mount rectangle diode and all that is printed on it is "DK" it seems to be open so I can't read anything off it. It's in a HP laptop by the power switch. TIA for any help.
