Yay, do you have any in TO-36 packages?
I first saw these in an old marine radio transmitter I was dismantling, there were a pair of them driving the high level modulator.
No TO-36s, Steve, I'm sorry. But some TO-3, and various tubby-looking Russian PNP germanium power types (150W) whose base numbers I couldn't even begin to guess at! You could probably get 100 SMDs into the same volume.

Makes me wonder how many home hobbyists give up in frustration because they can't get a circuit to work no matter how many times they check their work. And it's probably a mislabelled chip.
Indeed. Or a counterfeit one (see the other thread). Particularly bad if its an expensive chip not easily obtained, the temptation of buying them from less reputable suppliers is very high.
EPE should run another article on identifying these.

This is the second counterfeit/labelling fail thread in a while... its starting to get quite common, and I'm weary of ebaying power semiconductors now too.
And its hard to even give one specific seller a bad rep, cause they will just reopen a new store under some other name. Perhaps we should put together a list of reputable dealers?

This most definitely NOT a "counterfeit/labelling fail thread" - it's a mispacking error by one of the largest trade electronic suppliers in the world.
I doubt very much that Farnell (or RS/DigiKey/Newark etc.) would ever knowingly sell fakes - it'd completely ruin their businesses.

This is a straight QC issue.
I must say, Farnell aren't cheap, but I've always found them completely reliable.

Yes, let's not accuse Farnell of selling fake components. They might not be big in the USA, but they're huge in Europe, and a preferred supplier for lots of businesses, including the university where I work, and the two places I worked before that.
But they do make mistakes. The best one I ever got was a length of tape cut from a reel that was supposed to contain 0603 ceramic capacitors. I say "supposed" because in fact it was completely empty.
Harry: You should post pix of your Russian germanium transistors trampling some SOT23s to death.
