Subject says it all really, each power mosfet I find has a internal diode, anyone suggest and 100V 10A devices without diode ? Nobosy seems to make um like that :-\
cheers, Chris
power mosfet without diode ?

MOSFET's don't handle spikes. The diode is to protect from spikes in the opposite direction of the applied voltage, when using coils and such. Why is this a problem for you?

Becasue as per my other post, I am using one to soft start a supply rail, the problem is when the mosfet turns off, the smoothing capacitor's charge is flowing though the diode and keeping the mosfet from turning off..... I guess I will just have to block the reverse voltage with another diode..

Why
or perhaps two mosfets in series with one "backwards"?
