Vishay Semiconductors
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 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.

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 (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).
Note
Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluation. Typical values are for information only and are not part of the testing requirements.
