MOC3012XSMT&R

Triac, SCR Output Optoisolators Overview

The MOC3012XSMT&R is a zero-crossing triac output optocoupler manufactured by Isocom Components. It features an infrared LED coupled to a silicon bidirectional trigger diode (DIAC) and a triac, designed for AC power switching applications. The device provides electrical isolation between control circuits and high-voltage loads. Key specifications include a peak repetitive off-state voltage of 400V and a gate trigger voltage typically around 1.6V. It operates within a temperature range of -40°C to +105°C and is housed in a surface-mount SOIC-6 package.

Triac, SCR Output Optoisolators Feature Summary

• Zero-crossing detection capability minimizes electromagnetic interference during switching
• Integrated DIAC ensures precise triggering at the AC line voltage zero point
• High isolation voltage rating protects low-voltage control circuitry from high-voltage transients

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'XSMT&R' against official Isocom Components documentation to confirm surface mount packaging and tape-and-reel delivery format. Ensure compatibility with standard SOIC-6 footprint designs. Cross-reference datasheet parameters such as leakage current and thermal resistance with your system requirements before finalizing procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce noise in AC power systems. Compare its 400V blocking voltage against the peak line voltage of the application. Consider the surface mount form factor for automated assembly processes. Verify that the gate trigger characteristics align with the driving microcontroller or logic level outputs.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC301x series of zero-crossing optocouplers. It shares functional similarities with other industry-standard devices but is specifically identified under Isocom Components branding.
