AC Input Phototransistor Small Outline Surface Mount Optocoupler MOC256 MOC256 The MOC256 MOC256 is an AC input phototransistor optocoupler. The device consists of two infrared emitters connected in anti­parallel 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 SOIC­8 footprint.

Always design to the specified minimum/maximum electrical limits (where applicable). Current Transfer Ratio (CTR) = IC/IF x 100%. This specification guarantees that the higher of the two IC readings will be no more than 3 times the lower at IF = 10 mA. Input­Output Isolation Voltage, VISO, is an internal device dielectric breakdown rating. For this test, pins 1 and 2 are common, and pins 5, 6 and 7 are common.
