EL3043S1(TA)

Overview

The EL3043S1(TA) is a Triac and SCR output optocoupler manufactured by Everlight Electronics Co Ltd. It features a single channel with an SMD-6 package configuration. The device provides high isolation voltage of 5000Vrms and supports an operating temperature range from -55°C to +100°C. It is designed for zero-crossing triac driver applications, ensuring low electromagnetic interference during switching operations.

Feature Summary

• Integrated zero-crossing detection circuitry for precise AC load control
• High isolation voltage capability for safe signal transmission
• Surface-mount design suitable for automated assembly processes

Applications

• Solid-state relay drivers
• AC motor speed control circuits
• Lighting dimmer modules

Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against the manufacturer's latest datasheet before ordering. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing process. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when zero-crossing switching is required to minimize electrical noise in AC power control systems. Compare pinout compatibility and thermal performance with alternative SMD-6 optocouplers if space constraints exist. Validate that the isolation voltage rating meets the safety standards of the target equipment.

Part Context

This part belongs to the EL3043 family of Triac output optocouplers. It shares functional similarities with other Everlight devices like the EL3042 but differs in internal circuitry for zero-crossing functionality. The SMD variant offers compact footprint advantages over traditional DIP packages while maintaining equivalent electrical characteristics.

Replacement Considerations

EL3043S1(TA)-V is a verified substitute part number offering identical specifications and pinout compatibility.
