No, I mean IXYS, not Fairchild....

See here...

Keep in mind, someone we know may be bidding on the 1000v parts :wink:

Though it's darn hard to tell the way ebay is showing the bidder's usernames now... :roll:

seems to me our parts guys have a problem with infineon stuff.
I've been playing with MRF150s the past couple weeks.

I bid on the IXFH12N100s that he had, but didn't get them (my max bid was $100 for 27 of them).

There were other high voltage IXYS parts, but they were not a TO247 package (**NO M0UNTING HOLE**) which then requires an expensive clip to hold it down. Same with the driver IC he had - required more expensive mounting hardware (and takes up more room on the heat sink).

Good old Ebay :P

Regards,

Steve

Get used to weird mounting Steve. We have been going through a long learning curve with ball grids. Strap a ball grid on a board in a jet engine fuel control. Heat and vibration right up there. I think I still have some able stick in the freezer. It is used to glue substrates into hybrids.

I grabbed some 500volt linear parts to play with...

10 amp, 500v....

597pf input Ciss.

These are a recent part from IXYS, and currrently sell from IXYSRF for $25.77 each.!

There was one guy on there snapping as much of that stuff up as he could, for pretty good prices.

There's another round in about 5 days.....

IXYS RF FETS are very cool. good find. I'm in the process of building a gain block for my HPSDR exciter. Nobody can hear my PW 1/2 watt. I may drag out the linear parts box at some point and get back to my 9 300 watt blocks into a combiner and 1:3 transformer.

If you want a VERY fast part try the ARF461a and ARF461b. 5ns rise time and 12ns fall time. Package is Source for easy mounting. Rated to 60Mhz. (now the bad news) $43 each from Richardson.

Data sheet on the internet.

.34 RDS on at 2300 pf sounds unreal.

Gate resistance is actually the drive z to the gate to generate delay and transition times. Usually there is also a drive voltage around 10v with it. This has been around for a long time.
