When looking for a mosfet (or any other power transistor) and considering its speed how to I relate that to the frequency it can be switched at ? I know it will depend lergely on application maybe ? so if a mosfet has a turn on time of 60 ns and a turn off time of 45 ns thats 105 ns of more or less dead time in a cycle and you'd want this to be no more than about 10 % of each cycle or less meaning a 1050 ns cycle which is 1.05 ms so thats about 500 Hz - 1 KHz ?
