Opto Mosfets manufacturers

Hi all

I've been looking around for otpo mosfets manufacturers that provide
Form B (1NC) or Form C (1NO+1NC) mosfets. I'm was wondering if you knew
any beyond those:

Toshiba

Clare

Vishay

NAIS
http://www.nais-e.com/relay/photomos/photomos/photomos.html

Solid State Optronics

Nec

Omron

http://www.europe.omron.com/en/cor/ecb/home/productselector/Relays/MOSFET_Relays/


I also know about Fairchild, Agilent and Crydom but they do not have
Form B chips.

Thanks for any help.

IR, maybe.

What? Those aren't enough form-B SSR, depletion-mode FETs for you?

They are, but I'm trying to contact as much as I can, so that I maximise
my chances to get two form C chips.
You know, the larger the panel, the bigger the chances to get one which
responds.

Doesn't look like they do any Opto isolated stuff.
Thanks anyway.

They have a bunch of ssr's, but it looks like form A stuff only.

Yep, you're right, Form A only. They do have Opto isolated drivers
(PVI), so that it should be possible to drive depletion mosfets, but
that increases the size of the board.

Be careful you're not simply playing, delaying making a decision,
or putting off solving the more-complex ideal-distributor issue.

Well, if it was for a prototype project with production goals, this
would have long been sorted.
But this is for a personal project that can definitely afford to wait
because of lack of spare time on my side.
Hence the request to broaden the range of know manufacturers as most are
reluctant to help hobbyists.
But it seems it's a matter of time as well, I'm starting to get answers
to emails I sent a few weeks back. Not all are positive, but it may
happen that some are.
If in the end none are, well, I'll go for a regular electromechanical
relay, but that gets a big part of the fun out of the project.

Thanks for your help
