Description
The SFH615A (DIP) and SFH6156 (SMD) feature a
variety of transfer ratios, low coupling capacitance
and high isolation voltage. These couplers have a
GaAs infrared diode emitter, 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.
The couplers are end-stackable with 2.54 mm lead
spacing.
Creepage and clearance distances of > 8.0 mm are
achieved with option 6. This version complies with
IEC 60950 (DIN VDE 0805) for reinforced insulation
up to an operation voltage of 400 V
RMS
or DC.
Specifications subject to change.
Order Information
For additional information on the available options refer to
Option Information.
See TAPE AND REEL Section for 4-pin optocouplers T0 with 90
rotation.

= 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.
