The TIL3012 is a TRIAC output optocoupler, a device that provides galvanic isolation between a low-voltage control side and an AC load side. It is used to switch AC loads — such as solenoids, relays, small motors, or lamps — from a logic-level signal without a direct electrical connection. Typical applications include industrial controls, solid-state relay modules, and AC motor starters where isolation between the controller and the power circuit is required.
Packaging and handling note
Supplied in bulk packaging — loose parts in a tube or tray, not tape-and-reel. This suits bench-level assembly, prototype runs, or repair stock where pick-and-place is not used. For automated lines, verify that the part can be hand-loaded or request alternate packaging if available.
