Optocoupler Triac AC-OUT 1-CH 400VDRM 6-Pin PDIP White Bulk

The MOC303XM and MOC304XM devices consist of a AlGaAs infrared emitting diode optically coupled to a monolithic silicon detector performing the function of a zero voltage crossing bilateral triac driver.
They are designed for use with a triac in the interface of logic systems to equipment powered from 115VAClines such as teletypewriters, CTRs, solid-state relays, industrial controls, printers, motors, solenoids and consumer appliances, etc.
