MOC3071SM

Triac, SCR Output Optoisolators Overview

The MOC3071SM is a random-phase Triac driver optocoupler manufactured by onsemi. It features a single channel with an isolation voltage of 4170Vrms and a peak repetitive off-state voltage of 800V. The device operates within a temperature range of -40°C to 85°C. Key electrical parameters include a maximum DC forward current of 60mA, a typical holding current of 540µA, and a minimum static dV/dt of 1kV/µs. It is housed in a 6-SMD鸥翼 (gull-wing) surface-mount package.

Triac, SCR Output Optoisolators Feature Summary

• Provides galvanic isolation between control circuitry and high-voltage AC loads via a non-zero crossing Triac output.
• Designed for direct interface with microcontrollers or logic circuits to drive power Triacs in AC switching applications.

Triac, SCR Output Optoisolators Applications

• AC motor speed control systems
• Solid-state relay (SSR) designs
• General-purpose AC power switching modules

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SM' corresponds to the 6-SMD gull-wing package configuration rather than through-hole variants. Confirm RoHS compliance status and REACH declaration alignment with project requirements. Cross-reference the manufacturer part number against distributor catalogs to ensure correct component identification before ordering.

Triac, SCR Output Optoisolators Selection Notes

Select this component when non-zero phase angle firing is required for AC power control. Ensure the 800V blocking voltage meets the load requirements. Verify that the surface-mount footprint matches the PCB layout constraints. Consider thermal management capabilities within the specified operating temperature range during system design.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC3071M series of Triac driver optocouplers. It serves as a solid-state alternative to mechanical relays for AC load switching. The series provides reliable isolation and noise immunity for industrial and consumer electronics applications requiring precise AC power regulation.

Triac, SCR Output Optoisolators Replacement Considerations

Check datasheets for compatible alternatives such as the MOC3071M or MOC3072SVM. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure replacement parts meet the same isolation voltage and package type specifications.
