50V, 200 degrees C junction temp, 100 years lifetime.

Will be a while before you can buy any of those...

Nice. Check out the Arrhenius plot, though...they're extrapolating from
about a week's worth of data at 300C. Not the most persuasive data,
even by the dubious standards of accelerated aging. They might turn out
to be tasty to mice, for instance which of course would produce very
large 1/f noise. (This actually happened with undersea cables and
sharks, about 20 years ago.)

They do the same with DVDs and claim your data will be safe for 100 years....

That's great news. We blew up almost $1000 worth of Nitronex GaN fets
in two days.

Great news that it will be a while before you can blow up
some of these, or great news that they're being developed?

John, you brute, you're the stuff FETs--in their worst moments--dream
of. You *are* the thing which--for them--goes bump in the night!

My hat's off to you sir.

Fets nshould be like wine, "We shall sell no fets before their time",
which Nitronex sure did. GaN on silicon had/has a huge defect density.

My engineer who was working with these things, "samples" at $125 each,
told me he'd blown up four that morning. "Want too see?" he asked me.

I was wondering, "What's a HEMT?" so to not appear the ignoramus I put
it into google, and got this:
http://en.wikipedia.org/wiki/HEMT

It's very comprehensive, but can any of you gurun tell me if it's
accurate?
