100 pcs - SFH618A-5 Vishay, SFH618A-5 Phototransistor Output Optocoupler, Through Hole, 4-Pin DIP

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 circuitsGood CTR linearity depending on forward currentLow CTR degradationLow coupling capacitanceHigh common mode transient immunity
