MOC3073SR2VM

Triac, SCR Output Optoisolators Overview

The MOC3073SR2VM is a single-channel Triac and SCR output optocoupler manufactured by onsemi. It features a PhotoTriac output without a zero-crossing circuit, housed in a 6-pin MDIP surface-mount package. Key electrical parameters include an isolation voltage of 4170 Vrms, a maximum forward current of 60 mA, and an off-state output voltage (VDRM) of 800 V. The device operates within a temperature range of -40°C to +85°C and has a power dissipation rating of 330 mW.

Triac, SCR Output Optoisolators Feature Summary

• Provides electrical isolation between control circuits and high-voltage AC loads using a non-zero-crossing Triac output.

Triac, SCR Output Optoisolators Applications

• Solid-state relay driver circuits
• AC motor speed control systems
• Lighting dimmer applications

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SR2VM' against the official onsemi datasheet to confirm the tape-and-reel packaging configuration. Ensure that the required insulation voltage ratings meet the safety standards for the intended application environment. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Triac, SCR Output Optoisolators Selection Notes

Select this component when phase-angle control is required rather than zero-crossing switching. Verify that the load current does not exceed the Triac's peak current capabilities. Confirm that the 6-SMD package footprint matches the PCB design constraints. Check that the operating temperature range suits the environmental conditions of the final assembly.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC3073M series of Triac output optocouplers. It is designed for general-purpose AC power switching applications where galvanic isolation is necessary. The series offers various packaging options including through-hole and surface-mount configurations to accommodate different manufacturing processes.

Triac, SCR Output Optoisolators Replacement Considerations

Check for direct substitutes such as MOC3073SVM or MOC3073M depending on the required packaging type. Ensure any replacement maintains the same 800 V off-state voltage and 4170 Vrms isolation rating. Verify pinout compatibility if replacing with a different package style.
