ONSEMI MOC3042-M Optocoupler, Triac Output, DIP, 6 Pins, 7.5 kV, Zero Crossing,

The ONSEMI MOC3042-M is a 400V Zero Crossing TRIAC Driver Output Optocoupler that combines an AlGaAs infrared emitting diode with a monolithic silicon detector, performing the function of a zero voltage crossing bilateral TRIAC driver. It is engineered for use with a TRIAC in the interface of logic systems to equipment powered from 115VAC lines, including teletypewriters, CRTs, solid-state relays, printers, and solenoids.

This optocoupler simplifies logic control of 115VAC power, featuring zero voltage crossing for reduced inrush current and improved system reliability. It offers a typical dv/dt of 2000V/µs and a guaranteed 1000V/µs, along with a 400V peak blocking voltage, making it suitable for a range of power switching applications.

Key Features

• Zero voltage crossing for clean switching
• High dv/dt immunity: 2000V/µs typical, 1000V/µs guaranteed
• 400V peak blocking voltage
