DESCRIPTION
AGENCY APPROVALS
The SFH640 has a GaAs infrared emitting diode emitter,
which is optically coupled to a silicon planar phototransistor
detector, and is incorporated in a plastic DIP-6 package.
• UL
It features a high current transfer ratio, low coupling
capacitance, and high isolation voltage.
• CQC GB4943.1-2011
• cUL
• DIN EN 60747-5-5 (VDE 0884-5) available with option 1
• CQC GB8898-2011
The coupling device is designed for signal transmission
between two electrically separated circuits.
