Optocoupler/LED/nixie tube/photoelectric device

The FOD814 consists of two anti-parallel GaAs infrared light-emitting diodes that drive the output of a silicon phototransistor in a 4-pin dual column plug-inencapsulation. The FOD817 series contains Gallium Arsenide Infrared Emitting Diodes driving silicon phototransistors in a 4-pin dual column plug-inencapsulation.

The MOC3081M, MOC3082M, and MOC3083M devices consist of a GaAs infrared emitting diode optically coupled to a monolithic silicon detector, performing the function of a zero-voltage crossing double-sided triac driver. These devices can be used with discrete power triacs to interface logic systems with 240 VAC line-powered devices such as solid state relays, industrial controls, motors, solenoid valves, and consumer equipment.
