AC input/single transistor output photocouplers (optocouplers) are optically coupled isolators containing GaAs infrared light emitting diodes and an NPN silicon phototransistor. This type consists of two infrared light emitting diodes connected in inverse-parallel, and operates directly on AC input current.
