EL3082

Triac, SCR Output Optoisolators Overview

The EL3082 is a zero-crossing triac driver photocoupler manufactured by Everlight Electronics Co., Ltd. It features a 6-pin DIP package and provides electrical isolation with a 5000Vrms isolation voltage rating. The device integrates an infrared emitting diode on the input side and a zero-crossing triac output stage, designed for precise switching of AC loads at the mains voltage zero-crossing point to minimize electromagnetic interference.

Triac, SCR Output Optoisolators Feature Summary

• Integrated zero-crossing detection circuitry for synchronized AC load switching
• High isolation voltage capability for safe interface between low-voltage control circuits and high-voltage AC lines
• Compact six-pin dual in-line package suitable for standard PCB mounting

Triac, SCR Output Optoisolators Applications

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

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., TB, V) against the manufacturer's current datasheet to confirm packaging and availability status. Check for end-of-life notifications or obsolescence warnings before finalizing design-in decisions. Ensure compliance with RoHS directives as specified in the official documentation.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce noise in AC power applications. Confirm that the input forward current and output peak current ratings meet the specific load requirements. Verify the operating temperature range aligns with the environmental conditions of the target application.

Triac, SCR Output Optoisolators Part Context

This part belongs to the family of triac output optocouplers from Everlight. It is distinct from non-zero-crossing variants like the EL3041, offering reduced EMI during turn-on. The device serves as a critical interface component in industrial and consumer AC power control systems requiring galvanic isolation.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include other zero-crossing triac drivers such as the MOC3041 or PC814C equivalents, provided pinouts and electrical characteristics match. Always verify replacement compatibility with the original datasheet specifications.
