EL3022

Overview

The EL3022 is a six-pin DIP random-phase triac driver photocopler manufactured by Everlight Electronics. It integrates an aluminum gallium arsenide infrared emitting diode with a light-sensitive triac output. Key electrical parameters include a maximum isolation voltage of 5000 Vrms and a peak forward current of 60 mA. The device operates within a temperature range of -55°C to +100°C, featuring a maximum power dissipation of 330 mW and a holding current of 250 µA.

Feature Summary

• Random phase triggering capability for AC load control
• High insulation voltage rating for safety isolation
• Integrated infrared LED and light-sensitive triac

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration and pinout compatibility. Confirm that the component meets required isolation standards for the target application environment. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when random phase triggering is required for AC loads without external zero-crossing detection circuitry. Ensure the input current limits are respected to maintain optimal CTR performance. Verify that the package type and thermal characteristics align with the PCB layout constraints.

Part Context

This optotriac belongs to the EL302X series from Everlight Electronics. It is designed for general-purpose AC switching applications where galvanic isolation is necessary. The DIP-6 package facilitates through-hole mounting on standard printed circuit boards.

Replacement Considerations

Consult official substitution guides for compatible triac output optocouplers with matching isolation voltages and trigger currents.
