MOC3033SR2M

Triac, SCR Output Optoisolators Overview

The MOC3033SR2M is a single-channel Triac output optocoupler manufactured by onsemi, designed for interfacing logic systems with AC power devices. It features an integrated zero-crossing detection circuit to minimize electromagnetic interference during switching. The device provides high isolation voltage of 4170Vrms and supports a peak repetitive off-state voltage of 250 V. Key electrical parameters include a maximum DC forward current of 60 mA, a typical forward voltage of 1.25 V, and a maximum LED trigger current of 5 mA. It maintains a holding current of 400 µA and offers a minimum static dV/dt rating of 1 kV/µs. The component operates within a temperature range of -40°C to 85°C and is housed in a 6-SMD鸥翼 package.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix SR2M to confirm surface mount packaging and tape-and-reel availability. Ensure compatibility with RoHS3 and REACH regulations as specified by the manufacturer. Cross-reference UL certification details for safety compliance in end-product designs. Confirm lead times due to potential supply chain variability. Validate pinout alignment with PCB footprint requirements before integration.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce electrical noise in AC control applications. The 250 V off-state voltage rating limits suitability for higher voltage mains; verify against system requirements. Consider the 6-SMD form factor for space-constrained surface mount designs. Evaluate the 4170Vrms isolation barrier for appropriate safety standards. Compare trigger current specifications against available logic drive levels.

Triac, SCR Output Optoisolators Part Context
