EL3042S1(TA)-V

Overview

The EL3042S1(TA)-V is a Triac and SCR output optocoupler manufactured by Everlight Electronics. It features a single channel configuration with a minimum breakover voltage of 400 V and a maximum RMS isolation voltage of 5000 V. The device operates within a temperature range of -55 °C to +100 °C. Key electrical parameters include a maximum forward current of 0.06 A, a typical input trigger current of 15 mA, and a peak surge current of 1 A. It utilizes a surface mount 6-pin package and incorporates zero voltage crossing technology for the triac driver.

Feature Summary

• Integrated zero voltage crossing circuitry for the triac output stage
• High insulation voltage rating between input and output circuits
• Compliant with lead-free and RoHS environmental standards

Applications

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

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the received parts match the specific EL3042S1(TA)-V designation and packaging details. Ensure compliance with relevant safety certifications such as UL and VDE approvals documented in the official datasheet before integration into final products.

Selection Notes

Select this component when high isolation voltage and zero-crossing functionality are required for AC load switching. The 400 V breakover voltage suits low-voltage AC applications. Consider the surface mount package type for automated assembly processes. Verify thermal management requirements against the specified operating temperature range during design.

Part Context

This part belongs to the EL304X series of Triac output optocouplers from Everlight Electronics. The series includes variants with different breakover voltages, such as the EL303X (250 V) and EL306X (600 V). All members share common features like high isolation voltage and zero-crossing capabilities, tailored for various AC power control needs.

Replacement Considerations

Direct substitutes within the same family include EL3041S1(TA)-V and EL3043S1(TA). These alternatives share identical pinouts and functional characteristics but may differ in specific breakover voltage ratings or minor electrical tolerances. Verify compatibility with existing PCB layouts and thermal constraints.
