I want to control doorbell solenoids (12VAC low current, highly inductive) from microcontroller logic (5V TTL or 3.3V CMOS, a few mA available); is there an economical SSR or triac for this function, or is it best left to electromechanical relays?

depending on the current, check out MOC3020 opto triac
