EL3052-V

Overview

The EL3052-V is a random-phase triac driver optocoupler manufactured by Everlight Electronics. It features an internal zero-crossing detection circuit for low EMI switching of AC loads. The device provides electrical isolation with a rated isolation voltage of 5000 Vrms and a breakover voltage of 600V. Key electrical parameters include a forward voltage of 1.18V, a minimum static dv/dt rating of 1kV/µs, and a power dissipation capacity of 330 mW. It is housed in a standard 6-DIP package.

Feature Summary

• Integrates a zero-crossing detector to minimize electromagnetic interference during AC load switching
• Provides high-voltage isolation between control circuits and power triacs
• Designed for interfacing electronic controls with resistive and inductive AC loads

Applications

• Interfacing between electronic controls and power triacs
• Control of resistive AC loads
• Control of inductive AC loads

Procurement Notes

Verify the specific suffix (e.g., -V) against the manufacturer's current datasheet to confirm packaging and compliance details. Check official distributor channels for availability status, as supply constraints may apply. Ensure the component meets required isolation voltage ratings for the target application safety standards before procurement.

Selection Notes

Select this component when zero-crossing switching is required to reduce noise in AC control applications. The random-phase driver architecture suits general-purpose triac triggering. Verify that the 600V breakover voltage and 5000Vrms isolation meet the system's electrical safety requirements. Confirm compatibility with the intended load type, whether resistive or inductive.

Part Context
