Product
DC Input Single
-
DC input/single transistor output photocouplers (optocouplers) are optically coupled isolators containing a GaAs infrared light emitting diode and an NPN silicon phototransistor. This type is suitable for applications such as I/O interfaces and signal transmission circuits.
-
Product
DC 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.

Product
AC Input Single
-
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.

Product
Low Input Current
-
Low input current and transistor output photocouplers (optocouplers) are optically coupled isolators containing a GaAs infrared light emitting diode and an NPN silicon phototransistor. This type features a fast response while operating on a low input current.

Product
High Collector To Emitter Voltage
-
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.
