Optocoupler/LED/nixie tube/photoelectric device

The FODM214 series of single-channel DC-sense input optocouplers feature a compact half-pitch miniature flat 4-pin encapsulation that contains two gallium arsenide (GaAs) infrared light-emitting diodes that are optocoupled to a phototransistor in reverse parallel. coupling. The input-output isolation voltage VISO is rated at 3,750 VACRMS.

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

These devices consist of a gallium arsenide infrared light emitting diode optically coupled to a monolithic silicon phototransistor detector in a small surface mount plastic encapsulation. It is suitable for high-density applications without the need for through-board mounting.
