DESCRIPTION

The SFH620A (DIP) and SFH6206 (SMD) 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 or SMD 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 to an operation

voltage of 400 VRMS or DC.
