Optocoupler/LED/nixie tube/photoelectric device

The FODM121 series, FODM124 and FODM2701 include a Gallium Arsenide Infrared Emitting Diode driving a phototransistor within a compact 4-pin micro-flat encapsulation. Lead spacing is 2.54 mm. The FODM2705 consists of two Gallium Arsenide Infrared Emitting Diodes connected in anti-parallel for AC operation.

The MOC306XM and MOC316XM devices consist of a GaAs infrared light-emitting diode optically coupled to a monolithic silicon detector, performing the function of a zero voltage crossing double-sided triple driver. These devices are suitable for triacs in logic system interfaces from 115/240V AC line powered equipment such as solid state relays, industrial controls, motors, solenoid valves, and consumer equipment.
