A simple and quick question please clear this up.
Let's say I have a 350v rated power n channel mosfet , how much of positive voltage do i have to apply to the gate to fully open the mosfet?
I know this varies from type of transistor and so but the average?
i am just getting mixed up some things like the voltage drop let's say i need to apply 20 volts does that mean that on the Drain there will be my let's say 300v dc and then on the gate i should apply like 290 or something or i just should apply 20volts.
I guess I am saying is the gate voltage measured from the drain reference or from zero volts reference?
Thanks.
