EL3022S(TA)-V

Overview

The EL3022S(TA)-V is a single-channel random-phase triac output optocoupler manufactured by Everlight Electronics. It features a gallium arsenide infrared LED coupled to a triac detector within a 6-SMD gull-wing package. The device provides an isolation voltage of 5000 Vrms and supports a maximum repetitive peak off-state voltage of 400 V. Key electrical parameters include a forward current of 10 mA, a forward voltage of 1.18 V, and a power dissipation of 330 mW. It operates within a temperature range of -55°C to +100°C.

Feature Summary

• Random-phase triac output configuration for non-zero-crossing applications
• High isolation voltage capability of 5000 Vrms
• Compact surface-mount 6-SMD gull-wing packaging

Applications

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

Procurement Notes

Verify the specific suffix TA against official Everlight documentation to confirm the exact reel quantity and tape specifications. Ensure the component status remains active as supply chain conditions may change. Cross-reference the datasheet revision date with your design requirements to confirm parameter stability before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount solution is required for AC load switching without zero-crossing detection. The random-phase triggering allows for immediate conduction upon gate signal application. Consider the 400 V blocking voltage limit for low-voltage AC loads. Verify thermal management capabilities for the SMD package in high-density PCB layouts.

Part Context

This part belongs to the EL302X series of triac output optocouplers from Everlight. It serves as the surface-mount equivalent to through-hole DIP variants like the EL3022. The series is designed for general-purpose AC power control applications requiring galvanic isolation between low-voltage control logic and high-voltage AC lines.

Replacement Considerations

Direct pin-compatible replacements within the same family include other EL3022 variants with different packaging or suffixes. Verify that substitute parts maintain the 5000 Vrms isolation rating and 400 V off-state voltage. Check for any changes in the trigger current characteristics when swapping between different manufacturers.
