Optocoupler/LED/nixie tube/photoelectric device

The FODM217 series of single-channel DC sense input optocouplers contain a gallium arsenide (GaAs) infrared light-emitting diode in a compact half-pitch miniature flat 4-pin encapsulation. The input-output isolation voltage VISO is rated at 3,750 VACRMS.

The MOC3051M and MOC3052M consist of a GaAs infrared light-emitting diode optically coupled to a non-zero-crossing silicon diac (triac). These devices will come from a 115 V

The MOC3081M, MOC3082M, and MOC3083M 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.
