Optocoupler/LED/nixie tube/photoelectric device

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 MOC301XM and MOC302XM series are opto-isolated triac driver devices. These devices consist of a GaAs infrared light-emitting diode and a photosensitive silicon bidirectional switch that functions like a triac. These devices are suitable for use as an interface between electronic control and power triacs to control resistive and inductive loads operating at 115 VAC.

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 provides excellent common-mode rejection up to 50,000 V/µs.

The MOC306XM and MOC316XM devices contain a GaAs infrared light-emitting diode optically coupled to a monolithic silicon detector that performs the function of a voltage zero-crossing detection bidirectional triac driver.
