i want to replace a relay to switch Ac load(heater ) that will draw about 20 Amps . i used IRFP250 and bridge rectifier as in the picture . i still didn't do it . the voltage gate come from a plc (programmable logic controller) 24 Volt positive or negative .
will this circuit need any thing else ? will the mosfet need heat sink to act as a switch ?
