MOC3012SR2VM

Triac, SCR Output Optoisolators Overview

The MOC3012SR2VM is a single-channel Triac output optocoupler manufactured by onsemi. It features a gallium arsenide infrared LED coupled to a silicon photo-Thyristor (SCR) for isolation. The device provides an isolation voltage of 4170Vrms and supports a peak repetitive off-state voltage of 250V. It operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum DC forward current of 60mA, a typical forward voltage of 1.15V, and a maximum LED trigger current of 5mA. The component is housed in a 6-SMD鸥翼 package.

Triac, SCR Output Optoisolators Feature Summary

• Offers robust insulation capabilities suitable for industrial control environments

Triac, SCR Output Optoisolators Applications

• Solid-state relay driver circuits
• Industrial process control systems
• Motor control interfaces

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'R2' confirms the reel packaging format required for surface-mount assembly processes. Confirm that the 4170Vrms isolation rating meets the safety standards applicable to your target market, such as UL or IEC certifications. Ensure the 250V blocking voltage aligns with the load requirements of the controlled Triac or SCR. Check for RoHS compliance status if environmental regulations are a constraint for the final product assembly.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a non-zero-crossing Triac driver is needed for phase-angle control applications. The 6-SMD鸥翼 package facilitates automated surface-mount placement. Consider the 5mA maximum trigger current when designing the input LED drive circuit to ensure reliable switching. Verify that the operating temperature range of -40°C to +85°C covers the environmental conditions of the intended application site.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC301 series of Triac and SCR output optocouplers from onsemi. It is functionally similar to the MOC3012SM but differs in packaging configuration. The series is designed for general-purpose isolation between low-voltage control logic and high-voltage power stages. It serves as a critical interface component in AC power switching systems.

Triac, SCR Output Optoisolators Replacement Considerations

The MOC3012SR2M is a direct equivalent in terms of electrical specifications and pinout, differing primarily in packaging availability. For obsolete stock, the MOC3021S-TA1 from LITEON is listed as a similar alternative, though verification of specific electrical parameters and pin compatibility is required before substitution.
