AC Input Phototransistor
Small Outline Surface Mount
Optocoupler
The MOC256 is an AC input phototransistor optocoupler. The device consists
of two infrared emitters connected in antiâparallel and coupled to a silicon NPN
phototransistor detector. They are designed for applications requiring the
detection or monitoring of AC signals. These devices are constructed with a
standard SOICâ8 footprint.
