Description
SFH6286-2
CTR 63 - 200 %, SMD-4
The SFH628A (DIP) and SFH6286 (SMD) feature a
high current transfer ratio, low coupling capacitance
and high isolation voltage. These couplers have a
GaAs infrared emitting diode, which is optically cou-
pled to a silicon planar phototransistor detector, and
is incorporated in a plastic DIP-4 or SMD package.

The coupling devices are designed for signal trans-
mission between two electrically separated circuits.
For additional information on the available options refer to
Option Information.
The couplers are end-stackable with 2.54 mm lead
spacing.
Absolute Maximum Ratings
T
= 25 °C, unless otherwise specified
amb
Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the devise. 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.
