EL3051S1(TA)

Overview

The EL3051S1(TA) is a random-phase triac driver optocoupler manufactured by Everlight. It features a single channel with a photo-triac output and offers 5000Vrms isolation voltage. The device operates within a temperature range of -55°C to +100°C. It utilizes a 6-SMD surface-mount package configuration designed for compact circuit integration.

Feature Summary

• Random-phase triac output capability for AC load control
• High insulation voltage rating of 5000Vrms
• Extended operating temperature range suitable for industrial environments

Applications

• AC motor speed control systems
• Solid-state relay applications
• Lighting dimmer circuits

Procurement Notes

Verify the specific suffix TA against official Everlight documentation to confirm surface-mount packaging and tape-and-reel delivery format. Ensure the selected variant matches the required pinout and thermal characteristics for the target PCB layout. Cross-reference datasheet revisions to confirm material compliance and process change notifications prior to final procurement authorization.

Selection Notes

Select this component when random-phase triggering is required for AC loads without zero-crossing detection constraints. Compare the 5000Vrms isolation rating against system safety requirements. Evaluate the 6-SMD footprint compatibility against available board space. Consider the -55°C to +100°C operational range relative to ambient environmental conditions during design phase.

Part Context

This part belongs to the EL305x series of triac output optocouplers from Everlight. It shares functional similarities with other members like the EL3052S1(TA), differing primarily in internal gate drive characteristics and specific phase-triggering profiles. The SMD variant provides an alternative to through-hole DIP packages for automated assembly processes.
