EL3051S(TA)-V

Overview

The EL3051S(TA)-V is a random-phase triac driver optocoupler manufactured by Everlight Electronics Co Ltd. It features a six-pin surface-mount package designed for high-voltage isolation applications. The device provides an isolation voltage of 5000Vrms, ensuring robust separation between control and load circuits. Key electrical parameters include a forward voltage of 1.18V typical. It is classified as a Triac & SCR Output Optocoupler suitable for industrial environments.

Feature Summary

• Random-phase triac driver capability for AC load control
• High isolation voltage rating of 5000Vrms
• Surface-mount 6-pin package design

Applications

• Industrial motor control systems
• Solid-state relay modules
• AC power switching circuits

Procurement Notes

Verify the specific suffix TA-V against official Everlight documentation to confirm surface-mount configuration and tape-and-reel packaging requirements. Ensure compliance with RoHS directives and check for any regional supply restrictions or limited availability status before finalizing procurement plans.

Selection Notes

Select this component when random-phase triggering is required for AC loads without zero-crossing synchronization. The 5000Vrms isolation rating supports high-noise industrial environments. Confirm that the 6-SMD footprint fits the target PCB layout and that the forward voltage characteristics align with the driving logic levels.

Part Context

This part belongs to the EL305X series of triac output optocouplers from Everlight. It serves as a solid-state switch interface, replacing mechanical relays in applications requiring fast switching and long life. The SMD variant offers space-saving advantages over through-hole DIP versions while maintaining similar electrical performance standards.

Replacement Considerations

Direct substitutes within the same family include EL3052S(TA)(P5)-V. Verify pinout compatibility and isolation ratings when cross-referencing with other manufacturers' random-phase triac drivers.
