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.
