DESCRIPTION
• Low coupling capacitance
The SFH691AT has a GaAs infrared emitting diode emitter,
which is optically coupled to silicon planar phototransistor
detector, and is incorporated in a 4 pin 100 mil lead pitch
miniflat package. It features a high current transfer ratio, low
coupling capacitance, and high isolation voltage.
• End stackable, 0.100" (2.54 mm) spacing
The coupling devices are designed for signal transmission
between two electrically separated circuits.
• High density mounting or space sensitive PCBs
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• PLCs
• Telecommunication
AGENCY APPROVALS
• UL1577, file no. E52744 system code U
• cUL tested to CSA Bulletin 22.2 5A
• FIMKO
• DIN EN 60747-5-5 (VDE 0884)
• CQC GB4943.1-2011 (suitable for installation altitude
below 2000 m)

Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
(1) Refer to reflow profile for soldering conditions for surface mounted devices.
