Hey,
There are many mosfets for switching purposes, sometimes two of them conveniently packed into a single package.
Most of the times the datasheets provide data on the capacitances (Ciss, Coss, Crss) over drain to source voltage (GS shorted) and very few also provide data on the capacitances over positive gate to source voltage (DS shorted) like this one:
But I have not yet found data on the capacitances with negative gate to source voltage (talking about NMOS-FET).
I'd expect the capacitances to decrease, but I'd really like to see some data on that.
Does anyone here have some knowledge on the issue they would like to share?
Regards,
