EL3042S1(TA)

Overview

The EL3042S1(TA) is a zero-cross triac output optocoupler manufactured by Everlight Electronics Co Ltd. It features a single channel with surface mount SMD-6 packaging and provides 5000Vrms isolation voltage. The device operates within a temperature range of -55°C to +100°C. It includes an integrated zero-crossing detector for precise AC phase control applications.

Feature Summary

• Integrated zero-crossing detection circuitry
• High isolation voltage rating
• Surface mount package design

Applications

• AC power switching controls
• Solid state relays
• Motor speed controllers

Procurement Notes

Verify the specific suffix TA against the manufacturer datasheet to confirm tape and reel packaging specifications. Ensure compliance with RoHS directives and check for any regional supply restrictions or alternative package options before finalizing procurement orders.

Selection Notes

Select this component when zero-crossing functionality is required for low noise AC switching. Compare peak blocking voltage ratings against load requirements. Verify thermal management needs for the operating environment and ensure the SMD footprint matches the PCB layout constraints.

Part Context

This part belongs to the EL304X series of zero-cross triac drivers. It shares functional similarities with other Everlight optocouplers but is distinct in its specific zero-crossing timing characteristics and surface mount form factor compared to through-hole variants.
