MOC3042SR2VM

Triac, SCR Output Optoisolators Overview

The MOC3042SR2VM is a single-channel optoisolator from the MOC304 series, featuring a Triac output and integrated zero-crossing detection circuit. It utilizes surface-mount technology in a 6-SMD (gull-wing) package. The device provides an isolation voltage of 4170Vrms and supports a maximum DC forward current of 60mA with a typical forward voltage of 1.25V. It operates within a temperature range of -40°C to 85°C and offers a minimum static dV/dt of 1kV/µs.

Triac, SCR Output Optoisolators Feature Summary

• Integrated zero-crossing detection for reduced electromagnetic interference during switching
• High isolation voltage capability for safe signal transfer between circuits
• Surface-mount packaging design suitable for automated assembly processes

Triac, SCR Output Optoisolators Applications

• Solid-state relay driver circuits
• AC power control systems
• Motor speed control applications

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm that the received parts match the specified 6-SMD gull-wing package and MOC304 series designation. Ensure storage conditions comply with manufacturer guidelines to maintain reliability before soldering.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to minimize electrical noise in AC load control. Compare against non-zero-crossing variants like MOC3023 if phase-angle control is needed instead. Verify that the 4170Vrms isolation rating meets the specific safety requirements of the target application environment.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC304 family of Triac drivers designed for general-purpose AC switching. It differs from the MOC3042FR2VM by offering lower isolation voltage but maintaining similar functional characteristics. The SR2 suffix indicates the specific tape-and-reel packaging configuration used for high-volume manufacturing.

Triac, SCR Output Optoisolators Replacement Considerations

MOC3042FR2VM is listed as obsolete. Direct substitutes may include other MOC304 series devices with compatible pinouts and electrical ratings, provided isolation voltage differences are acceptable.
