Just fell over this looking for something else: A ready-made cascode transistor, like the discrete ones I used in my exam project 25 years ago. Now, where can I get some Oil to put it in?:)

Huh - 2200V Transistor?

They are suggesting it for switching use. I wonder how it would do running in linear mode at several mA.
It would also be nice if they put some extra clearance between those pins.
Seems to me that one must be rather careful with the driving circuitry, to control reverse base biasing - wich can kill the beta...
In actual fact, the mosfet emitter switch EBjn is expected to avalanche on turn-off and large gains (>4) should not be expected, regardless of 'typ' specs. The characteristics are stable.
I'd not seen anything above 1500V in this series before.
They've done a fair job with the package and pin-out, to anticpate the increased functional creepage distances on printed wiring and on the body.
