Vishay, SFH619A Photodarlington Output Optocoupler, Surface Mount, 4-Pin DIP

The Vishay Optocoupler has a GaAs infrared emitting diode emitter, which is optically coupled to a silicon photodarlington detector, and is incorporated in a plastic DIP-4 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.

High collector emitter voltage, VCEO = 300 V
Low coupling capacitance
High common mode transient immunity
Isolation rated voltage 5000 VRMS
Standard plastic DIP-4 package
