If I am using a mosfet as a switch, I assume there is no trick to the vds needed. If i want to switch 100V, i need vds to be greater than 100V correct?
I have been trying to find a surface mount mosfet to switch 500V with a load current of 20A. This seemed easy until i actually took the Rtheta into account. It seems that all of these 500V mosfets rated at 20A will melt far before they ever get to 20A. Does this seem correct?
If both of these statements are correct, is it time for me to look at igbt's?
Thanks for any help.
