I need help in using a power mosfet to switch on and off 140 VDC. The
current is approximately 25 amps. The power will be on for one second
at a time, then off for twenty seconds. I have an old part number IRF
243, but it is no longer available. A mosfet in that class, 16 amp 150
volt 125 watt or higher would work. I need to know how to operate this
mosfet including how many volts to turn it on and the placement of any
resistors or other components to make it operate as a relay.
