Vishay, SFH617A-4 Phototransistor Output Optocoupler, Through Hole, 6-Pin DIP

The Vishay SFH617A is the couplers have a GaAs infrared diode emitter, which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a plastic DIP-4 package. The coupling devices are designed for signal transmission between two electrically separated circuits.

Low saturation voltage
Fast switching times
