MOC3042M Description

Short technical summary and product information.

The ON Semiconductor MOC3042M is a 6-pin DIP optoisolator featuring a Triac driver output. It is designed to simplify the logic control of 115 VAC power systems. This device includes a zero voltage crossing circuit, making it suitable for applications requiring clean switching of AC loads.

 

Key electrical specifications include a maximum continuous forward current of 60 mA and a maximum LED trigger current of 10 mA. The off-state output terminal voltage is rated at 400 V, with an isolation surge voltage of 7500 Vac(pk). The typical forward voltage is 1.25V, and the typical hold current is 400 µA. It offers a static dV/dt of 1 kV/µs.

 

This optocoupler is mounted through hole and comes in a standard 6-DIP package. The operating temperature range is -40°C to 85°C. The MOC3042M is recognized by UL.

 

Applications for the MOC3042M include solenoid and valve controls, lighting controls, static power switches, AC motor drives, temperature controls, and solid-state relays.
