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 FOD410, FOD4108, FOD4116, and FOD4118 devices consist of an infrared light-emitting diode coupled to a hybrid triac formed using two antiparallel SCRs to form a single triac capable of driving a discrete triac. Triac function. The FOD4116 and FOD4118 utilize a high-efficiency infrared light-emitting diode to provide enhanced trigger sensitivity. These devices use a standard 6-pin dual-inline plug-in (DIP) encapsulation.
