EL3081S(TA)

Overview

The EL3081S(TA) is a surface-mount triac output optocoupler from Everlight Electronics. It integrates a GaAs infrared emitting diode with a zero-crossing triac detector. Key electrical parameters include a peak blocking voltage of 600V, an isolation voltage of 5000Vrms, and a forward current of 60mA. The device operates within a temperature range of -55°C to +100°C and features a 6-SMD Gull Wing package.

Feature Summary

• Integrates zero-voltage crossing circuitry for reduced electromagnetic interference during switching.
• Provides high isolation capability between input and output circuits.
• Designed for direct interface with logic systems controlling AC power loads.

Applications

• Solid-state relays
• Motor control circuits
• Lighting control systems

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm pinout and packaging variations. Ensure compliance with regional safety standards such as UL or VDE requirements for the intended end-use application before finalizing component selection.

Selection Notes

Select this component when a surface-mount solution is required for AC load switching with built-in zero-crossing detection. Consider the 600V blocking voltage rating relative to the line voltage and ensure thermal management supports the specified operating temperature range.

Part Context

This part belongs to the EL308X series of triac output optocouplers. It shares architectural similarities with other models in the family but is distinguished by its specific 600V peak blocking voltage rating and surface-mount gull-wing package configuration.

Replacement Considerations

Cross-reference with EL3083S(TA) for higher voltage ratings or EL3041S1(TA)-V for lower voltage applications. Verify pin compatibility and isolation voltage specifications before substitution.
