The TIL3020 is a triac output optocoupler — an optically isolated switch that uses an LED to trigger an internal triac, letting a low-voltage DC control signal switch an AC load. The bulk package means it ships loose in a bag, not on a reel; fine for bench builds or repair stock, less convenient for pick-and-place.
The TIL3020 is active and RoHS non-compliant.
