Y4 diode identification

[Zilicon]

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

It's a 12V unidirectional TVS diode.

Thanks

Please can I have the datasheet?

And please, how do I source for datasheet of stuff like this?

S-manual.com was not really helpful

I haven't been able to find a datasheet. I just know from experience that HDDs have two TVS diodes (5V and 12V) at the power inputs.These can usually be replaced with SMAJ12A/SMAJ5A, SMBJ12A/SMBJ5A or SMCJ12A/SMCJ5A, depending on dimensions.Also be aware that there is often a 4A smt fuse (marked "S") in series with each diode.

Thanks a lot.

S-manuals.com seem to lead me astray.

TVS make more sense than what S-manuals is giving me, especially considering how it was arranged in the circuit.

How wish there's a reliable website where one can identify these parts easily

Maybe this:

Thank you.

I saw something related too. All pointed to a zener diodes. Different diodes with different electricl characteristics.

It can't be a zener. A zener is far too slow, for a start.

Exactly.
