Optocoupler/LED/nixie tube/photoelectric device

The FODM121, FODM124, and FODM2701 series contain Gallium Arsenide Infrared Emitting Diodes that drive phototransistors in compact 4-pin miniature flat enclosures. The lead pitch is 2.54 mm. The FODM2705 series consists of two GaAs IR LEDs connected in anti-parallel for AC operation.

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