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.
