MOC3033SR2VM

Triac, SCR Output Optoisolators Overview

The MOC3033SR2VM is a single-channel Triac driver output optocoupler from onsemi's MOC series, designed for surface mount technology (SMT) in a 6-pin SMD package. It integrates an infrared emitting diode coupled to a zero-crossing triac detector, enabling snubberless operation with discrete triacs. Key electrical parameters include a maximum forward voltage of 1.5V, a maximum input current of 60mA, and an isolation voltage of 4170Vrms. The device operates within a temperature range of -40°C to 85°C and features a static dV/dt of 1kV/µs minimum.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a zero-crossing triac detector for precise AC phase control and snubberless driving capability.
• Provides high-voltage isolation between input and output circuits to ensure system safety.
• Designed for surface mount assembly to facilitate automated manufacturing processes.

Triac, SCR Output Optoisolators Applications

• Solid-state relay (SSR) driver circuits
• AC power switching applications
• Motor speed control systems

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required zero-crossing variant. Check for RoHS compliance status and lead time availability as supply chain conditions may vary. Ensure storage conditions adhere to moisture sensitivity level requirements prior to assembly.

Triac, SCR Output Optoisolators Selection Notes

Select this component when snubberless triac driving with zero-crossing detection is required in a compact surface mount form factor. Consider the 4170Vrms isolation rating for high-voltage separation needs. Evaluate the 60mA maximum input current against the driving circuit capabilities. Ensure the operating temperature range aligns with the environmental conditions of the target application.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC303x series of Triac driver optocouplers, which are widely used for controlling AC loads. The SR2VM suffix indicates a specific surface mount package configuration with zero-crossing functionality. It is distinct from DIP versions like the MOC3033M and serves as a modern alternative for PCB space-constrained designs.

Triac, SCR Output Optoisolators Replacement Considerations

The MOC3033SVM is listed as a direct substitute by the manufacturer. Verify pinout compatibility and parameter equivalence before replacement. Other generic Triac driver optocouplers may require circuit modifications due to differences in isolation voltage or trigger characteristics.
