Vishay Mosfet group going under?

Yes, good point. I bought 10 or 25 of those last year, don't remember, but I've been too busy on AoE III to take any measurements. But finishing the new low-noise chapter will be coming up shortly, so that should be a good excuse to break them out and go to the bench.

They do. That's why they have "in stock" > 0, on some parts. With other more expensive parts they're fronted (consignment, essentially).

Even large end customers have consignment deals. But usually when a part becomes scarce the lights go out pretty much everywhere. Disties do have stock beyond others on occasion but it's mostly not enough to avoid running dry. BT, many times :-(

They don't have to be large. They keep some of our inventory, but that wasn't my point.

They normally keep stock of the common parts, mostly passives, and some of them *are* getting scarce. Yes, if a part is scarce they aren't likely to have any either. ;-)

Well, you can sit in the dark in a state of depression because your party is out of power. The rest of the world carries on doing business.

Look at the bright side: Mental health will be covered under Obamacare.

See, that's where my futures trading comes in. Some investor could buy the rights to 200,000 MSP430F5513 for delivery in November at $3.10 a pop. Whoever delivers them either must do so or pay a contract penalty. The investor runs the risk that they aren't scarce and he might lose 50c to a buck per chip. If they turn out to be scarce he'll make a serious profit.

Of course not from me cuz I'd rather stick with the 80C51 :-)

You keep demonstrating your cluelessness.

Are you competing for the DimBulb prize this week? You're getting there, but DimBulb isn't going to let you have an easy time. Keep working.

Need some?

Thanks, my clients buy those. But there was never any shortage as far as I can remember. The first one I used in the early 90's, and the whole thang is still in production.

Seriously, I have some Intel 87C51FCs around here somewhere. Neat part, but not good for much more than a hurt foot, anymore.

Well, mine are still good for something :-)

They help getting patients out of a not so cool cardiac situation.

By sticking 40 pins in their feet?

Nope, it's a 44-PLCC :-)

...won't even feel it. ;-)

I was looking for 2N4117's and 9's recently (ultra low C and leakage JFETs) for protecting sensitive inputs in a diode-connected configuration. Distributor said Vishay had discontinued them, I contacted Vishay who said they discontinued them a couple of years ago when they changed the line to a different process but there had been massive stocks in hand so it wasn't obvious at first. I don't think Vishay are pulling out of JFETs completely.

Fairchild make MMBF4117/9 and there's also an SP4117/9 from some other company. But both are on many week leadtime. So I wonder if these old but good parts may be incompatible with modern fab processes, which would be a pain.

Can anyone recommend a more available low leakage JFET along these lines? I'm wondering if everyone's moved onto a more modern part and I just hadn't heard 8)

BFT25A C-B junctions are at least as good as 2N4117As as diodes.

It's not just Vishay.
