This datasheet provides detailed information on the SFH618A/628A couplers, including features, applications, specifications, characteristics, charts and pinouts.
The SFH618A and SFH628A are optocouplers designed for signal transmission between two electrically separated circuits. They feature a GaAs infrared emitting diode emitter optically coupled to a silicon planar phototransistor detector, housed in a plastic DIP-4 package. These devices are specified for high current transfer ratio (CTR) and low coupling capacitance.
