The MOC119 device consists of a gallium arsenide infrared emitting diode optically coupled to a monolithic silicon photodarlington detector. The chip to Pin 6 connection has been eliminated for better performance when used in high noise environments.
It is designed for use in applications requiring high improved noise immunity.

• Provides Higher Output Collector Current (IC) with Lower Values of Input Drive Current (IF)
• To order devices that are tested and marked per VDE 0884 requirements, the
   suffix ”V” must be included at end of part number. VDE 0884 is a test option.

Applications
• Appliance, Measuring Instruments
• Interfacing and coupling systems of different potentials and impedances
• Monitor and Detection Circuits
