EL3053S1(TB)-V

Overview

The EL3053S1(TB)-V is a Triac and SCR output optocoupler manufactured by Everlight Electronics Co Ltd. It features a random-phase TRIAC driver designed for surface mount applications in a 6-SMD package. The device provides electrical isolation with a rated voltage of 5000Vrms across one channel. Key electrical characteristics include a maximum on-state RMS current of 100mA, a typical hold current of 250µA, and a maximum LED trigger current of 5mA. This component serves as a compact interface solution for controlling AC loads.

Feature Summary

• Random-phase TRIAC driver configuration suitable for zero-crossing detection circuits
• High isolation voltage rating of 5000Vrms for enhanced safety in mains applications
• Surface mount SMD-6P packaging for automated assembly processes

Applications

• Solid state relay (SSR) modules
• Motor speed control systems
• Lighting dimmer circuits

Procurement Notes

Verify the specific suffix 'V' against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications. Ensure that the 6-SMD footprint matches the target PCB design. Cross-reference the 5000Vrms isolation rating with system safety requirements. Confirm RoHS compliance status through official environmental documents before finalizing procurement orders.

Selection Notes

Select this component when high-voltage isolation is required between control logic and AC power stages. The random-phase capability allows triggering at any point in the AC cycle, making it distinct from zero-crossing variants. Evaluate the 100mA RMS current limit against the load requirements. Consider the SMD form factor for space-constrained designs requiring robust triac gate drive.

Part Context

This part belongs to the family of Triac and SCR output optocouplers offered by Everlight. It complements other models like the EL3053S1(TA)-V, which typically utilizes a DIP package instead of the SMD configuration found in the TB variant. These devices are categorized under general-purpose optoisolators designed for industrial and consumer electronics control applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult the manufacturer's official replacement guide or cross-reference tools for verified alternatives. Direct pin-to-pin replacements may require verification of isolation voltage and current ratings.
