VISHAY SFH640 is an optocoupler with good CTR linearity and low CTR degradation. It has a very high collector-emitter breakdown voltage, suitable for telecommunications applications or any DC application requiring a high blocking voltage.
The SFH640 is a phototransistor output optocoupler with a base connection, offering a minimum 300 V collector‑emitter breakdown voltage and low coupling capacitance. It is supplied in a 6‑pin DIP package and complies with RoHS and various safety standards.
The document provides absolute maximum ratings, electrical characteristics, switching times, package dimensions, and environmental compliance information, useful for designers selecting a high‑voltage isolation component.
