DESCRIPTION
The SFH615A feature a variety of transfer ratios, 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 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 mm are achieved
with option 6. This version complies with IEC 60950
DIN VDE 0805) for reinforced insulation up to an operation
voltage of 400 VRMS or DC. Specifications subject to
change.
