Optocoupler/LED/nixie tube/photoelectric device

The FODM100x series of single-channel DC-sense input optocouplers feature a stretched body SOP 4-pin encapsulation containing a gallium arsenide (GaAs) infrared light-emitting diode optically coupled to a phototransistor. The input-output isolation voltage VISO is rated at 5,000 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
