EL3042M-V

Overview

The EL3042M-V is a Triac and SCR output optocoupler manufactured by Everlight Electronics. It features a PhotoTriac output designed for interfacing logic systems with equipment powered from AC lines ranging from 110 to 380 VAC. The device provides high isolation voltage of 5000 Vrms between input and output channels. It is housed in a 6-pin DIP package suitable for through-hole mounting.

Feature Summary

• Designed for interface applications between logic systems and AC-powered equipment
• Provides high electrical isolation between input and output circuits
• Utilizes a PhotoTriac output structure for direct triac triggering

Applications

• Solid-state relay interfaces
• Motor control circuits
• Lighting control systems

Procurement Notes

Verify component authenticity against official Everlight documentation. Confirm that the specific suffix matches the required isolation and packaging specifications. Ensure compliance with relevant safety certifications such as UL and VDE before integration into final products.

Selection Notes

Select this component when interfacing low-voltage logic signals with medium-to-high voltage AC loads. Consider the 5000 Vrms isolation rating for safety requirements. Evaluate the thermal characteristics and peak current capabilities relative to the driven triac's gate requirements.

Part Context

This part belongs to the EL304X series of Triac output optocouplers. It shares architectural similarities with other members like the EL3041 and EL3043, differing primarily in specific electrical ratings or internal circuit configurations such as zero-crossing detection.

Replacement Considerations

Compatible substitutes include the EL3041 and EL3043 from the same manufacturer family. Verify pinout compatibility and ensure the alternative part meets the required isolation voltage and output current specifications.
