DESCRIPTION

The SFH615A feature a variety of transfer ratios, 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 lead spacing.

Creepage and clearance distances of > 8 mm are achieved

with option 6. This version complies with IEC 60950

(DIN VDE 0805) for reinforced insulation up to an operation

voltage of 400 VRMS or DC. Specifications subject to

change.
