MOC3031VM

Triac, SCR Output Optoisolators Overview

The MOC3031VM is a single-channel, through-hole optocoupler from the onsemi MOC series. It features an internal zero-crossing circuit and a photoTriac output rated for 250V VDRM. The device provides 5250Vrms isolation voltage and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum forward current of 60mA, a forward voltage of 1.25V, and a maximum trigger current of 15mA. It is housed in a 6-pin PDIP package.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a zero-crossing detection circuit to minimize electromagnetic interference during switching.
• Provides high-voltage isolation between input and output circuits via a photoTriac architecture.
• Designed for robust operation across extended industrial temperature ranges.

Triac, SCR Output Optoisolators Applications

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official datasheets. Confirm that the specific suffix matches the required zero-crossing functionality and voltage ratings. Ensure compliance with relevant safety certifications such as UL and VDE before integration into final products.

Triac, SCR Output Optoisolators Selection Notes

Select this component when AC load switching with low noise is required. The integrated zero-crossing feature distinguishes it from random-phase variants. Consider the 250V output rating and 5250V isolation level against system requirements. Verify availability status as product lifecycle stages may affect long-term supply.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC303XM family of Triac and SCR output optocouplers. It shares architectural similarities with models like the MOC3031M but includes specific packaging and testing variations indicated by the VM suffix. The family is designed for general-purpose AC power control applications requiring galvanic isolation.
