EL3052S(TA)-V

Overview

The EL3052S(TA)-V is a single-channel triac output optocoupler manufactured by Everlight Electronics. It features a six-pin surface-mount device (SMD) package designed for interfacing electronic controls with power triacs. The component supports random-phase triggering and provides high surge current capabilities for the output stage. It offers an isolation voltage of 5000 Vrms and a peak repetitive off-state voltage of 600 PBV. The operational temperature range spans from -55°C to +100°C, ensuring reliability in various industrial environments.

Feature Summary

• Single-channel triac output configuration for direct load control
• Random-phase triggering capability for AC load management
• High surge current handling capacity at the output terminal
• Robust electrical isolation between input and output circuits

Applications

• Interfacing microcontrollers with resistive loads
• Controlling inductive loads in AC power systems
• Solid-state relay driver circuits
• Industrial automation control modules

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest documentation to confirm pinout and packaging variations. Ensure compliance with RoHS directives as indicated in official product data sheets. Confirm availability status through authorized distributors, as supply constraints may affect immediate procurement. Cross-reference the Mouser part number 638-EL3052SV with the manufacturer's catalog to validate authenticity and technical specifications before ordering.

Selection Notes

Select this component when surface-mount integration is required for AC load switching applications. The random-phase feature allows triggering at any point in the AC cycle, suitable for non-zero-crossing requirements. Verify that the 600 PBV rating meets the peak voltage demands of the connected load. Consider the SMD-6 package dimensions for PCB layout compatibility and thermal management needs within the specified operating temperature range.

Part Context

This device belongs to the EL3052 family of triac output optocouplers from Everlight. It shares functional similarities with through-hole variants like the EL3052M but utilizes a surface-mount form factor. The series is commonly used in appliances and industrial equipment requiring galvanic isolation between low-voltage control logic and high-voltage AC power stages.

Replacement Considerations

Check for equivalent parts such as the EL3052S1(TA) or other random-phase triac drivers from compatible manufacturers. Ensure substitute components match the SMD-6 package outline and maintain similar isolation voltage ratings. Verify that alternative devices support the same surge current capabilities and operational temperature ranges.
