DESCRIPTION
The SFH615A features a large variety of transfer ratio,
low coupling capacitance and high isolation voltage.
These couplers have a GaAs infrared emitting diode
emitter, which is optically coupled to a silicon planar
phototransistor detector, and is incorporated in a plas-
tic DIP-4 package.
The coupling devices are designed for signal transmis-
sion 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
950 (DIN VDE 0805) for reinforced insulation up to an
operation voltage of 400 V
RMS
or DC.
Specifications subject to change.
