MOC3083 Datasheet

Triac & SCR Output Optocouplers


The MOC3083 devices consist of a GaAs 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 discrete power triac in the interface of logic systems to equipment powered from 240 VAC lines, such as solid-state relays, industrial controls, motors, solenoids and consumer appliances,etc. MOC3083 Features • Underwriters Laboratories (UL) recognized -file #E90700, Volume 2• VDE recognized - file #102497 - add option V(e.g., MOC3083VM)• Simplifies logic control of 240 VAC power• Zero voltage crossing• dv/dt of 1500V/ps typical, 600V/ps guaranteed• Compatible with Fairchilds FKPF12N80 discrete power triac MOC3083 Applications • Solenoid/valve controls• Lighting controls• Static power switches• AC motor drives• Temperature controls• E.M. contactors• AC motor starters• Solid state relays
