DESCRIPTION
The SFH61XA features a high current 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 phototransis-
tor 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.
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 opera-
tion voltage of 400 V
RMS
 or DC.
