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 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.

The HCPL05XX and HCPL04XX optocouplers consist of an AlGaAs LED optically coupled to a high-speed photodetector transistor in a compact 8-pin small footprint encapsulation.
