The SFH6156-3 is a 1-channel 4-pin 10mA high reliability Phototransistor Output Optocoupler has a GaAs infrared diode emitter, which is optically coupled to a silicon planar phototransistor detector. The SFH6156 features a variety of transfer ratios, low coupling capacitance and high isolation voltage. The coupling device is designed for signal transmission between two electrically separated circuits.
Excellent CTR linearity depending on forward current
