The SFH610A and SFH6106 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 spacing.
Creepage and clearance distances of > 8.0 mm are
achieved with option 6 and option 8. This version complies
with IEC 60950 (DIN VDE 0805) for reinforced insulation up
to an operation voltage of 400 VRMS or DC. Specifications
