Optocoupler/LED/nixie tube/photoelectric device

Foot length 4mm

The FOD814 consists of two Gallium Arsenide infrared emitting diodes in a 4-pin dual-wire encapsulation, connected in anti-parallel, driving a silicon phototransistor output. The FOD817 series includes a Gallium Arsenide Infrared Emitting Diode driving a Silicon Phototransistor within a 4-pin 2-in-line encapsulation.

The MOC3071M, MOC3072M, and MOC3073M consist of a GaAs infrared light-emitting diode optically coupled to a non-zero crossing silicon triac (triac). These devices isolate low voltage logic from the 240 VAC line and provide random phase control of high current triacs or thyristors. These devices feature enhanced static dv/dt capability to ensure stable switching performance for inductive loads.

The 6N135M, 6N136M, HCPL4503M, HCPL2530M, and HCPL2531M optocouplers consist of an AlGaAs LED optically coupled to a high-speed phototransistor. A separate connection for photodiode biasing reduces the base-collector capacitance of the input transistor and is orders of magnitude faster than conventional phototransistors. The HCPL4503M has no internal connection to the phototransistor base, improving noise immunity. Internal interference shielding with excellent common-mode rejection up to 50,000 V/µs.
