EL3022S1(TA)-V

Overview

The EL3022S1(TA)-V is a single-channel Triac output optocoupler manufactured by Everlight Electronics. It features a GaAs infrared emitting diode optically coupled to a Triac detector, providing random-phase triggering capability. The device offers high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum forward current of 60 mA, a typical forward voltage of 1.18 V, and a peak off-state voltage of 400 V. The unit operates within a temperature range of -55°C to +100°C and is housed in a 6-SMD surface-mount package.

Feature Summary

• Random-phase Triac output for AC load control
• High insulation voltage of 5000 Vrms
• Surface-mount 6-SMD package design

Applications

• Solid-state relay (SSR) modules
• AC motor speed control circuits
• Lighting dimmer applications

Procurement Notes

Verify the specific suffix TA against the manufacturer datasheet to confirm pinout and packaging configuration. Ensure compliance with RoHS3 standards as indicated in distributor records. Confirm availability status due to potential supply restrictions mentioned in recent inventory data. Cross-reference the component number with official Everlight documentation to validate authenticity before integration into production designs.

Selection Notes

Select this component for applications requiring random-phase triggering without zero-crossing detection. Compare the 400 V peak off-state voltage against circuit requirements to ensure adequate margin. Consider the 6-SMD footprint for PCB layout constraints. Evaluate the 5000 Vrms isolation rating for safety compliance in mains-connected designs. Verify thermal dissipation capabilities within the specified operating temperature range.

Part Context

This part belongs to the EL302X series of Triac output optocouplers from Everlight. The series includes variants such as EL3023 and EL3022, distinguished by specific trigger characteristics and packaging options. These devices are designed for general-purpose AC switching applications where galvanic isolation is required between control logic and high-voltage AC loads.

Replacement Considerations

Direct substitutes may include other random-phase Triac optocouplers with similar 5000 Vrms isolation and 6-SMD packages. Verify compatibility of trigger current specifications and peak voltage ratings. Check for equivalent certification approvals such as UL and VDE when replacing in certified equipment.
