DESCRIPTION
The SFH618A/628A feature a high current transfer ratio, low
coupling capacitance and high isolation voltage. These cou-
plers have a GaAs infrared emitting diode emitter, which is
optically coupled to a silicon planar phototransistor detector,
and is incorporated in a plastic DIP-4 package.
The coupling devices are designed for signal transmission
between two electrically separated circuits.
The couplers are end-stackable with 2.54 mm spacing.
Therefore multicouplers can easily be implemented and con-
ventional multicouplers can be replaced.
Creepage and clearance distances of >8 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.
