The Vishay optocoupler with phototransistor output has a GaAlAs infrared emitting diode, which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a 4-pin mini-flat package. It features a high current transfer ratio at low input current, low coupling capacitance, and high isolation voltage. The coupling devices are designed for signal transmission between two electrically separated circuits, specifically for use in automotive, as well as high reliable industrial applications.

It has high CTR with low input current
It is compliant to RoHS directive and lead free
It is AEC-Q101 qualified
