EL3041S(TA)-V

Overview

The EL3041S(TA)-V is a surface-mount Triac output optocoupler featuring an AlGaAs infrared emitting diode optically coupled to a phototriac. It includes integrated zero-crossing detection circuitry for low electromagnetic interference switching. The device offers 5000 Vrms isolation voltage and supports a minimum off-state peak voltage of 400 V. Key electrical parameters include a maximum forward current of 60 mA, a typical holding current of 280 µA, and a static dV/dt rating of 1 kV/µs. It operates within a temperature range of -55 °C to +100 °C.

Feature Summary

• Integrated zero-voltage crossing detection for reduced noise generation
• High insulation strength between input and output circuits
• Surface mount packaging for automated assembly

Applications

• Isolation of AC line voltages for resistive, inductive, or capacitive loads
• Control of motors, solenoids, and high-current TRIACs
• Solid-state relay driver interfaces

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and specific tape-and-reel packaging details prior to ordering. Ensure the procurement source provides valid traceability documentation matching the Everlight Electronics part number EL3041S(TA)-V to prevent counterfeit components.

Selection Notes

Select this component when zero-crossing functionality is required to minimize inrush currents and EMI in AC control applications. The 400 V blocking voltage suits standard 120 VAC and 240 VAC systems. Verify that the 100 mA RMS on-state current meets load requirements. Consider the SMD-6 package constraints for PCB layout and thermal management during design.

Part Context

This device belongs to the EL304X series of Triac output optocouplers manufactured by Everlight Electronics. The series differentiates primarily by peak breakdown voltage ratings, with the EL304X variant specifically rated for 400 V. These devices are designed for general-purpose AC power switching where galvanic isolation and noise reduction are critical system requirements.

Replacement Considerations

Direct pin-compatible replacements within the same family include EL3041S(TB)-V. Cross-brand substitutions require verification of isolation voltage, trigger current thresholds, and zero-crossing timing characteristics to ensure functional equivalence.
