Identity of component
Hello, does anyone know what this is please?
It seems to be a unidirectional TVS, but can't be sure. It's fitted in part of a SMPS that provides a supply to some 24V fans.

Could this be it? http://www.ic-on-line.cn/search.php?...07l&stype=part

Re: Identity of component
My vote goes for this:

Re: Identity of component
How about a Polyswitch, if it's in series.... but the end marking argues against that so the unidirectional TVS looks best so far

Re: Identity of component
I think I'm with Chris, a 3A schottky. I don't think an inductor would have a polarity bar.
The V3J is the giveaway. I was googling P807L and getting nothing with those device markings. edit: after research: P807L is a Plant & Date code. 3 = current rating (3A) J = voltage code (J=100V) I'll fit one and report back if it works.
