Description
The SFH617A (DIP) feature a high current transfer
ratio, low coupling capacitance and high isolation volt-
age. These 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 trans-
mission between two electrically separated circuits.
