Vishay, VO618A-3 Phototransistor Output Optocoupler, Through Hole, 4-Pin

The Vishay Optocoupler feature a high current transfer ratio, low coupling capacitance and high isolation voltage. 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 transmission between two electrically separated circuits. The couplers are end-stackable with 2.54 mm spacing. Creepage and clearance distances of > 8.0 mm are achieved with option 6 and 8.
