DESCRIPTION

The SFH620AA, SFH620AGB features a high current

transfer ratio, low coupling capacitance and high isolation

voltage. These couplers have a GaAs infrared emitting 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 lead spacing.

This version complies with IEC 60950 (DIN VDE 0805) for

reinforced insulation up to an operation voltage of 400 VRMS

or DC.
