Nice gate charge.

Cheers

What the heck is the use for U4, Figure 24?

Cannot e too picky at $100 per electron..

U3 and U4 look like they should be isolated DC-DC converter blocks, but are poorly drawn.

gate drain 103 nC????

At 1700 V?

Internal gate resistance in the few Ohms range Would not be sure how to drive that thing...

Ahh, can I ask some silly questions? Why is it called a junction transistor with gate, source and drain. It looks like a fet? Jfet? Then they draw it later as a bipolar transistor. And the gate source "leakage" current is 20nA?

It's for high end critical application products, nothing cheap.

And they're thinking:

It seems to act like a bipolar transistor, but with 3 volts Vbe on.

Once you start doing heterojunction tricks, zillions of possibilities open up, nuch more than what you can do by doping silicon.

I've noticed a bipolar mode in e-phemts, namely lots more drain current when the gate begins to conduct.
