I am running a 12V 2A power supply to a 12V blower and using an IRF840 as a switch. https://www.vishay.com/docs/91070/sihf840.pdf
There is 1.2A running from Drain to Source. When I put 12V from the supply to the gate with a parallel line, the MOSFET becomes shorted and will continue to conduct after the 12V is removed from the gate. If I leave the 12V connected to the gate, it eventually starts smoking.
