MOC3020SR2M

Triac, SCR Output Optoisolators Overview

The MOC3020SR2M is a random-phase triac driver optocoupler manufactured by onsemi. It features a single channel with a Triac output, housed in a 6-SMD surface-mount package. The device provides an isolation voltage of 4170Vrms and supports a maximum DC forward current of 60 mA. It operates within a temperature range of -40°C to 85°C and includes no zero-crossing circuitry. Key electrical parameters include a peak off-state voltage of 400 V, a typical holding current of 100 µA, and a typical forward voltage of 1.15 V.

Triac, SCR Output Optoisolators Feature Summary

• Provides galvanic isolation between control circuits and high-voltage AC loads via optical coupling.
• Features a random-phase triggering mechanism for immediate triac activation upon signal input.
• Designed for surface-mount assembly in compact electronic applications.

Triac, SCR Output Optoisolators Applications

• Isolating low-voltage control signals from high-voltage AC loads
• Driving triacs in solid-state relay circuits
• AC power switching applications

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SR2M' to ensure the correct tape-and-reel packaging configuration. Confirm that the non-zero-crossing characteristic aligns with the application requirements, as this variant differs from zero-crossing models. Check for RoHS compliance status and ensure the operating temperature range meets environmental constraints.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase triggering is required rather than zero-crossing behavior. Ensure the 400V blocking voltage is sufficient for the target AC line voltage. Verify that the 6-SMD footprint fits the PCB layout and that the 4170Vrms isolation rating satisfies safety standards for the intended interface.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC302X series of triac driver optocouplers. It shares the same functional architecture as other variants in the family but differs in packaging and specific electrical tolerances. The series is designed for general-purpose AC power control applications requiring reliable isolation.
