Hi, I'm plaing to make a thermal switch, and i want to do it with a transistor (relays click anoyingly) but I'm not sure of what transistor I should use. The voltage throught the transistor will be about 12 volts and the current about 5 amps. Now I'm wondering if anyone could help me, will a normal biopolar (BD243) do the job or would it be better with a fet, or even a mosfet?
Thanks for any explanation!
