Description
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.
The coupling devices are designed for signal trans-
mission between two electrically separated circuits.

Absolute Maximum Ratings
T_amb = 25 °C, unless otherwise specified
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 Rating for extended periods of the time can adversely affect reliability.
