DESCRIPTION

The VOS628A series 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.

FEATURES

? High CTR with low input current

? Low profile package (half pitch)

? High collector emitter voltage VCEO = 80 V

? Isolation test voltage = 3750 VRMS

? Low coupling capacitance

? High common mode transient immunity
