Vishay, SFH640-2 Phototransistor Output Optocoupler, Through Hole, 6-Pin DIP

The Vishay SFH640 Optocoupler has a GaAs infrared emitting diode emitter, which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a plastic DIP-6 package. It features a high current transfer ratio, low coupling capacitance, and high isolation voltage. The coupling device is designed for signal transmission between two electrically separated circuits.

Isolation rated voltage: 5000 VRMS
Low coupling capacitance
High common m
