DESCRIPTION

The SFH615A-3X018T 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.

FEATURES

• Excellent CTR linearity depending on forward

current

• Isolation test voltage, 5300 VRMS
