Description
The SFH618A (DIP) and SFH6186 (SMD) feature a
high current transfer ratio, low coupling capacitance
and high isolation voltage. These couplers have a
GaAs infrared diode emitter, which is optically cou-
pled to silicon planar phototransistor detector, and is
incorporated in a plastic DIP-4 or SMD package.
The coupling devices are designed for signal trans-
mission between two electrically separated circuits.
For additional information on the available options refer to
Option Information.
