DESCRIPTION
The SFH615XXX features a large assortment of 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
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 60950
(DIN VDE 0805) for reinforced insulation up to operation
voltage of 400 VRMS or DC.
