EL3023-V

Overview

The EL3023-V is a single-channel Triac and SCR output optocoupler manufactured by Everlight Electronics. It features a random-phase Triac driver phototransistor input coupled to a four-layer silicon structure. The device provides high isolation with an insulation voltage of 5000 Vrms and supports a peak off-state voltage of 400 V. Key electrical parameters include a maximum forward current of 60 mA, a forward voltage of 1.18 V, and a power dissipation of 330 mW. It operates within a temperature range of -55°C to +100°C and utilizes a DIP-6 package for through-hole mounting.

Feature Summary

• Provides galvanic isolation between control circuits and high-voltage AC loads via a Triac output stage.
• Features a random-phase output configuration suitable for general AC switching applications without zero-crossing detection.
• Offers robust electrical isolation capability rated at 5000 Vrms to protect low-voltage control circuitry.

Applications

• Solid-state relay (SSR) modules
• AC motor speed control circuits
• Lighting dimmer switches

Procurement Notes

Verify the specific suffix requirements when ordering, as packaging and tape/reel configurations may vary between standard DIP and surface-mount variants. Confirm compliance with RoHS directives and regional safety certifications such as UL or VDE before finalizing procurement specifications. Ensure that the selected variant matches the required thermal management and mechanical mounting constraints for the target assembly process.

Selection Notes

Select this component for applications requiring isolation between low-power logic signals and higher-power AC loads. Consider the 400 V blocking voltage limit when designing circuits to ensure adequate margin against transient spikes. Evaluate the 60 mA forward current requirement for the LED side to determine appropriate series resistance values. Verify that the operating temperature range aligns with the environmental conditions of the intended deployment scenario.

Part Context

The EL3023-V belongs to the broader EL3023 series of optocouplers designed for industrial and consumer AC control applications. This series typically includes variations in packaging and output characteristics to suit different manufacturing needs. The device serves as a critical interface component in systems where electrical separation is mandatory for safety and noise immunity, bridging microcontroller outputs with mains-powered devices.

Replacement Considerations

Cross-reference with other random-phase Triac output optocouplers from Everlight or alternative manufacturers offering similar 5000 Vrms isolation and DIP-6 packaging. Ensure that substitute parts match the pinout configuration and electrical ratings, particularly the peak off-state voltage and trigger current specifications, to maintain circuit functionality without redesign.
