Description
The SFH618A (DIP) and SFH6186 (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 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
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.
