Vishay, SFH6156-4 DC Input Phototransistor Output Optocoupler, Surface Mount, 4-Pin SMD

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.

Excellent CTR linearity depending on forward current
Isolation test voltage, 5300 VRMS
Fast switching times
APPLICATIONS:
Switchmode power supply
Telecom
Battery powered equipment
