High Collector To Emitter Voltage

Renesas Electronics Corp.

High collector-to-emitter voltage photocouplers (optocouplers) are optically coupled isolators containing a GaAs infrared light emitting diode and an NPN silicon Darlington connected phototransistor. The isolation voltage during input and output and the voltage between the collector and the emitter of the transistor are both high.
