EL3041-V

Overview

The EL3041-V is a single-channel Triac output optocoupler featuring zero voltage crossing capability. It integrates a Gallium Arsenide infrared emitting diode with a Triac output device, designed for interfacing logic systems to AC power lines ranging from 110 to 240 VAC. The component offers high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a minimum off-state peak voltage of 400V, a maximum forward current of 60mA, and a peak surge current of 1A.

Feature Summary

• Zero voltage crossing functionality reduces electromagnetic interference during switching
• High isolation voltage between input and output circuits ensures safety
• Compatible with standard surface mount or DIP packaging options
• Compliant with RoHS standards and lead-free manufacturing processes

Applications

• Interface between logic systems and equipment powered from 110 to 240 VAC lines
• Solid state relay driver circuits
• Motor control applications requiring AC switching
• Lighting control systems for AC loads

Procurement Notes

Verify the specific suffix (e.g., TA, TB) against the required package type, as these indicate different physical footprints such as surface mount or through-hole configurations. Confirm regulatory approvals like UL and VDE are present on the datasheet for the specific variant being procured. Ensure the ordering code matches the exact isolation and voltage ratings required for the target application safety standards.

Selection Notes

Select this component when zero-crossing detection is required to minimize noise in AC switching applications. Consider the 400V blocking voltage rating for compatibility with standard line voltages. Evaluate the thermal management requirements given the operating temperature range up to 100°C. Compare alternative series members if higher voltage ratings or different package styles are needed for the specific board layout constraints.

Part Context

This part belongs to the EL304X series of Triac output optocouplers manufactured by Everlight Electronics. The series includes variants with different peak breakdown voltages, such as 250V, 400V, 600V, and 800V options. These devices are widely used in industrial and consumer electronics for isolated control of AC power devices, providing galvanic isolation between low-voltage control circuits and high-voltage AC loads.

Replacement Considerations

Direct substitutes within the same family include EL3041S1(TA)-V or EL3041S1(TB)-V, which share identical electrical characteristics but may differ in package style. Verify that any replacement maintains the 5000 Vrms isolation rating and zero-crossing feature. Cross-reference pinouts and mechanical dimensions to ensure compatibility with existing PCB layouts.
