MOC3042SVM

Triac, SCR Output Optoisolators Overview

The MOC3042SVM is a surface-mount triac output optocoupler from the MOC series. It features a single channel with zero-crossing detection for low EMI switching of AC loads. The device provides high isolation voltage and operates within a temperature range of -40°C to 85°C. Key electrical parameters include a maximum forward voltage of 1.5V, a maximum input current of 60mA, and a maximum trigger current of 10mA. It utilizes a 6-pin SMT package and complies with UL 1577 and DIN EN/IEC 60747-5-5 standards.

Triac, SCR Output Optoisolators Procurement Notes

Verify that the specific suffix 'SVM' corresponds to the required surface mount package and tape-and-reel or tube configuration as defined by onsemi. Confirm compliance with relevant safety certifications such as UL 1577 for the intended application environment. Ensure the zero-crossing feature aligns with system requirements for noise reduction in AC switching scenarios.

Triac, SCR Output Optoisolators Selection Notes

Select this component when surface mount technology is required for AC load control with minimal electromagnetic interference. The zero-crossing feature distinguishes it from random-phase variants, making it suitable for sensitive electronic environments. Verify that the 400V blocking voltage and 10mA trigger current meet the specific load characteristics of the target circuit design.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC304XM family of triac output optocouplers. It shares functional similarities with through-hole variants like the MOC3042M but differs in mounting style and package dimensions. The 'SVM' suffix specifically denotes the surface mount version with tin terminal finish, distinguishing it from other packaging options within the same electrical specification family.

Triac, SCR Output Optoisolators Replacement Considerations

Direct replacements must maintain zero-crossing functionality and surface mount compatibility. Equivalent parts may include other MOC304x series devices with matching pinouts and isolation ratings. Verify that substitute components offer identical trigger current specifications and comply with the same safety agency approvals.
