Jeff,
Rik, Markus,
Mouser GB sells the STGW30NC60WD IGBT, at £3-60
each. See the link below. You can download a data sheet from the same
site.
Farnell UK also sell them:-

Hello Markus and Rick!
I have only just acquainted myself with your
messages.
(Just going out from hospital, big blood pressure
problem...)
Thanks a lot for precious information, of what
make fun still!
I recovered some ferrites N87 types which should
work in 137 KHZ.
Another subject interests me, it is the
possibility of transmitting with a big spool of several turns (a bit as
WD2XDW). But EIRP is much weaker than with a vertical aerial, then it is
necessary to "push more" in power!

Jeff, Marcus,
STGW30NC60WD has a turnoff delay of
120ns. Turn on delay and rise / fall times are better than 30ns.
That
should be good enough for 137kHz, maybe even for 500kHz.
It further has a
max. Collector-Emitter Voltage of 600V, max. Collector Current
of 60A (200A pulsed), max.. dissipation of 200W and a saturation voltage of
2V (@20A).
Looks like a good "workhorse" for those who want to
experiment with IGBT's.

Dear
Jeff,
havn't actually tried it myself on
137 kHz. But from past experience I'd say that while IGBTs may have less
DC loss, they are much slower (especially during turnoff). They can be
used as effient switches at some tens of kHz, whereas MOSFETs will easily
go up to several MHz.
Kind
regards,
Markus, DF6NM

- Good night to all,
- Anybody would have any experience on the use of IGBT in
136 KHz amplifiers?
- Thanks in advance!
