Vishay, VOS628A-X001T AC Input Phototransistor Output Optocoupler, Surface Mount, 4-Pin SSOP

The Vishay The Vishay optocoupler with phototransistor output has a GaAs infrared emitting diode emitter, which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a 4-pin 50 mil lead pitch mini-flat package. It features a high current transfer ratio at low input current, low coupling capacitance, and high isolation voltage. The coupling devices are designed for signal transmission between two electrically separated circuits.

It is compliant to RoHS directive and lead free
It has high CTR with low input current
