VISHAYSFH618A-5Optocoupler
The Vishay SFH618A feature a high current transfer ratio, low coupling capacitance and high isolation voltage. These coupler have a GaAs infrared diode emitter, which is optically coupled to silicon planar phototransistor detector, and is incorporated in a plastic DIP-4 package. The coupling device are designed for signal transmission between two electrically separated circuits Good CTR linearity depending on forward current Low CTR degradation Low coupling capacitance High common mode transient immunity
