Well, it happened--the last fast PNP is EOL

BFT92, RIP.

NXP, you lousy bastards, you just took away about a quarter of my design
space. Get 'em while they last.

Let's hope that at least _these_ stay for some time..

cheers, Gerhard

Yeah, true, there are those. Unfortunately their Rbb' and Ree' are the
pits.

I just bought Newark's last reel of BFT92s, so we'll be okay for our own
stuff, but I can't use them in custom or licensed designs any more.

Which is a great pity--fast PNP wraparounds are good for a lot of things.

Cheers

Should start a s.e.d. fabless semiconductor company and get them made
again, China will make whatever you like. You could advertise it as
exactly that "The Last Fast PNP" like the Last of the Mohicans or something.

It's be nice to have it available in a SOT-323 SC70 package.

Maybe you and Hobbs should buy a wafer or two? Then, as time moves
on, package them to suit the era?

Octopart shows 44,909 at Digikey. These are BFR92P: 2GHz, not 5GHz. See the

Scratch that. BFT92 is PNP

Discrete device wafers are dirt-cheap and low profitability. That's
why the devices are being phased out. Was anyone besides Hobbs buying
them?

I think everyone here who uses them regularly should let us all know
just how many they use per annum and exactly how precious the last of
these fast PNPs are because y'know...<checks total web stock, checks

I sure was. And a lot of SOT-89 parts, now gone too.

If the wafers are cheap, somebody could bake a crate full of them,
jack up the device prices, and do OK. And not annoy a lot of
maybe-future customers.

You could buy some, put them in a nitrogen cabinet and 10 years down the

They're still available from NXP till November, though I don't know how
many more wafers they'll actually be processing.

One reel is probably enough for my needs, but this move puts some of my
customers in a bit of a jam. I just got a call this morning to redesign
a circuit from a year or two back, and I expect there'll be more. Not
the sort of new business I'm most fond of.

NXP. What a bunch of morons.

Since they're unique parts, perhaps we could persuade Lansdale or
Rochester to make them--the litho resolution would be doable with very
old equipment. Do you still have contacts there? I'd really like to be
able to get the NE97733 again, too (8.5 GHz PNP).
