MOC3071TVM

Triac, SCR Output Optoisolators Overview

The MOC3071TVM is a random-phase triac driver optocoupler manufactured by onsemi. It features an infrared LED coupled to a zero-crossing detection circuit and a triac output, providing isolation for AC load control applications. The device operates with a peak repetitive off-state voltage of 400V and supports continuous forward current up to 100mA for the input LED. It offers high common-mode transient immunity and is designed for reliable switching in industrial and consumer electronics environments.

Triac, SCR Output Optoisolators Feature Summary

• Integrates zero-crossing detection circuitry to minimize electromagnetic interference during AC switching operations
• Provides galvanic isolation between control logic and high-voltage AC loads via internal optical coupling
• Features robust construction with high common-mode transient immunity for stable performance in noisy environments

Triac, SCR Output Optoisolators Applications

• Solid-state relay drivers for industrial machinery
• AC motor speed control circuits
• Lighting dimmer switches and controllers
• Heating element control systems

Triac, SCR Output Optoisolators Procurement Notes

Verify that the specific suffix 'TVM' corresponds to the tube packaging variant as indicated by distributor listings. Confirm RoHS compliance status through the official datasheet or product compliance documents before finalizing procurement. Ensure the ordering quantity aligns with the factory pack quantity of 1000 units typically associated with this packaging style.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce electrical noise and stress on AC loads. It is suitable for applications requiring moderate isolation voltage and reliable triac triggering. Consider thermal management if driving multiple devices in close proximity, although the internal structure minimizes external heat generation compared to non-isolated solutions.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3071M series of triac driver optocouplers. It shares functional similarities with other members like the MOC3061 but includes integrated zero-crossing detection. The T/V/M suffixes typically denote package type (DIP) and packaging format (Tube), distinguishing it from tape-and-reel variants such as the MOC3071SR2VM.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes include the MOC3061M for non-zero-crossing applications, though switching characteristics differ. For identical zero-crossing functionality, verify pinout compatibility with other manufacturers' random-phase triac drivers. Always check isolation voltage ratings and peak current capabilities against the original design requirements.
