SFH619A product information
Optocoupler, Photodarlington Output, High Gain, 300 V BVCEO
The SFH619A 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.
