Optocoupler/LED/nixie tube/photoelectric device

The FOD852 includes a Gallium Arsenide Infrared Emitting Diode within a 4-pin dual inline plug-inencapsulation driving a silicon photo Darlington output (with integrated base emitter resistor).

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 for increased trigger sensitivity. These devices use a standard 6-pin dual-inline plug-in (DIP) encapsulation.

The HCPL4502M, HCPL4503M, HCPL2503M, 6N135M, 6N136M, HCPL2530M, and HCPL2531M optocouplers consist of an AlGaAs LED coupled to a high-speed photodetector transistor. By reducing the base-collector capacitance of the input transistor, a separate connection for photodiode biasing increases speed by several orders of magnitude over conventional phototransistor optocouplers. The HCPL4503M is not internally connected to the phototransistor base to help improve noise immunity, and the internal noise shield provides best-in-class common-mode rejection up to 50,000V/µs.
