Description
The SFH620A (DIP) and SFH6206 (SMD) feature a
high current transfer ratio, low coupling capacitance
and high isolation voltage. These couplers have a
GaAs infrared diode emitter, which is optically coupled to a silicon planar phototransistor detector, and
is incorporated in a plastic DIP-4 or SMD package.
The coupling devices are designed for signal transmission 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
to an operation voltage of 400 V
RMS
or DC.

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.
