DESCRIPTION

The SFH6156 features a variety of transfer ratios, low

coupling capacitance and high isolation voltage. This

coupler has a GaAs infrared diode emitter, which is optically

coupled to a silicon planar phototransistor detector, and is

incorporated in a plastic SMD package.

The coupling devices are designed for signal transmission

between two electrically separated circuits.
