Applied Power Technologies lists a whole host of datasheets on their website at: http://category.alldatasheet.com/index.jsp?components=Power%20MOSFETS

and I thought the APT8043 series looked like it might do what we are looking for. Its reverse transfer C is only 68pF and its a 800V 20A device.

has anybody seen the APT components in use anyplace? :?:

thanks

http://category.alldatasheet.com/index.jsp?components=Power%20MOSFETS. sorry here is the corrected URL- theres a list of all the APT devices here from large to small.

APT is now microsemi.com

Some of the ARF series (and DRF) look promising,

The DRF 1200 ?.. is a hybrid driver/mosfet.... but $160 each!!

They have some interesting FETs, and there are some cool app notes using those devices ... all obsolete, of course!

IXYS and DEIC have great looking parts.... but, again, fairly expensive....

Unfortunately... just the way it is...... for right now.....

Broadcast Electronics used APT MOSFET's in the Class E 1KW AM-1A transmitter. I believe they used the APT6018 which is a 600V FET with RDS of .18ohms

I purchased a few APT6015 a few years ago from Richardson Electronics and they were about $15.00 each. Not sure what APT FET's sell for these days.

They're worth looking into.
