lucky MOSFET find

Gang,

Just as the human eyes adjust to the conditions of the available light,
they adjust to spot the contour of parts that are needed for current
projects.
Like today, when I took a stroll on the local scrapyard, and suddenly
found myself staring at a heap of IXYS IXTN79N20 MOSFET`s carefully
removed from what appears to be working equipment.

I grabbed 30 pcs. and wondered if they could be made to do service in an
audio modulated SSTC, for example.

They don`t appear on http://www.ixys-dot-com
but from the type markings they appear to be 79A 200V types.
In the unloaded state, the Gate-Source capacitance is 17.7nF, but this
might change.

How do i test them?

I tried hooking one sample up to a motorcycle lead battery, and apply 12
volts to the gate, that caused current to flow, so that the isotop
casing got hot, didn`t break it.

But there has to be a better way, and I don`t want to break my
Plasmatronic board by just plugging them in, to see what happens.

Cheers, Finn Hammer
