DESCRIPTION

The 110 °C rated SFH617A (DIP) feature a high current

transfer ratio, 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 spacing.

Creepage and clearance distances of > 8.0 mm are

achieved with option 6.
