EL3052S1(TA)

Overview

The EL3052S1(TA) is a Triac and SCR output optocoupler manufactured by Everlight Electronics Co Ltd. It features a random-phase triac driver suitable for AC power control applications. The device provides 5000 Vrms isolation voltage between the input LED and output triac. It operates within a temperature range of -55°C to +100°C. The component is housed in a surface-mount package with a reel factory packaging quantity of 1000 units.

Feature Summary

• Random-phase triac output configuration
• High isolation voltage rating
• Wide operating temperature range

Applications

• AC power control circuits
• Solid-state relay drivers
• Motor speed control systems

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to ensure correct pinout and electrical characteristics. Confirm RoHS compliance status through the provided environmental files. Check current supply availability as stock levels may be restricted or subject to change based on regional distribution channels.

Selection Notes

Select this component when random-phase triggering is required for AC loads rather than zero-crossing switching. Ensure the system design accommodates the specified isolation voltage requirements. Verify that the surface-mount package type aligns with the PCB layout constraints and assembly capabilities of the manufacturing process.

Part Context

This part belongs to the Triac & SCR Output Optocouplers category under the broader Optocouplers subcategory. It is distinct from zero-crossing variants like the EL3041 series. The product line includes various package options and isolation ratings tailored for industrial and consumer electronics power management.
