Sanity check - transistor id

A monitor back light supply has a bjt with the marking: C5706. Mouser has an ON bjt, number 2SC5706. Can I assume that they're the same?



Thanks, Bob


C5706 == 2sc5706, yes.

Yes.

It's common practice (has been for years), to drop the "2S" part on small devices.

There are other series where they do the same thing.

Right, like "D" = 2SDxxx. K = 2SKxxx, I think. (Don't remember how they handled 3SKxxx).

KEC parts are common (Korean Electronic Components or something), which are KT-. Example: I've pulled some "C3206" from monitors before; these are:

and so on. I don't know if all KEC parts are in funny packages, but this "TO-92L" at least is distinctive. If the 2S part doesn't turn up, or just doesn't look right, give this a try.

I implied that.
