WebDC Input Darlington. DC input/Darlington transistor output photocouplers (optocouplers) are optically coupled isolators containing a GaAs infrared light emitting diode and an NPN silicon Darlington connected phototransistor. This type can operate on a low-current DC input because of its Darlington configuration.
