Hi Everybody, I currently use a small relay to change the NC status of a PIR passive to power a relay switch to sound a buzzer. Now the relay eats about 20mA at 12V, but I want loads of these, so soon I'll be drawing massive amps. I know a transistor can do what a relay does, but can anyone point me to the right resources where I find out how to replace the relay with transistors?
I am looking in particular for transistor specs, i.e. how many mA can the transistor drive, and what volatage can it handle. Thanks for your help.
