Trying to source 2 diodes : )

Support Q&A

22TB San Disk Professional drive. A diode blown and guessing I should change both. The white filter next to it too. The blown diode has AV in the middle and a small t26 towards the bottom. The other diode has a 74 and the white filter thing has two M’s. The blown diode in the photo is aprox 4mm x 2mm.

Hi @theupel2 ,

The “AV” guy is probably Nexperia’s PTVS12VP1UP.

Cheers, heke

Hello, theupel2.
To identify a diode marked “74,” you need to provide its exact dimensions and a high-quality photo of diode.

Using my DigiKey ruler is about 1.5mm x 2.5mm.

AV is about 3.75mm x 2.25mm

They are a perfect fit for slot R and T on your ruler

You guys need to send me a better ruler. LOL !

The white component MM (fuse?) is the same size as the AV diode. It does not beep.

theupel2,
Your diode marked “74” is the RB160MM-40.
RB160MM-40TR
And the white component marked “MM” is a Murata PKGS shock sensor.

A shock sensor! Didn’t know there was a thing. LOL! So I am guessing that component is still good. It was not dropped. Thank you so much Adam7 !
