Thanks for answering. That seems to confirm that it's possible. There is no need
to specify the parts you use, just whether they are ordinary or special. I
looked at some datasheets and the dV/dt I will be seeing is well within spec
(10x and over) of what these parts can do. Any special measures ? Holding the
gate with a low value resistor ?

thanks,
Peter P.
