EL3022M

Overview

The EL3022M is a random-phase Triac output optocoupler manufactured by Everlight Electronics. It integrates an AlGaAs LED with a Triac detector in a 6-pin DIP package. Key electrical parameters include a holding current of 250 µA, a maximum LED trigger current of 10 mA, and a peak on-state current of 100 mA RMS. The device provides an isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to 100°C.

Feature Summary

• Integrates an AlGaAs infrared emitting diode with a random-phase Triac detector for isolated switching.
• Provides high isolation voltage capability suitable for safety-critical applications.
• Designed for direct interfacing with microcontrollers and logic circuits.

Applications

• Solid-state relays
• Motor control circuits
• Lighting control systems

Procurement Notes

Verify the specific suffix (e.g., P5) against the manufacturer's datasheet to confirm pinout and packaging details. Ensure the component meets required isolation standards for the target application. Cross-reference the part number with official Everlight documentation to avoid counterfeit or obsolete stock.

Selection Notes

Select this component when random-phase triggering is acceptable for AC load control. Verify that the 100 mA RMS current rating suffices for the load requirements. Confirm that the 5000 Vrms isolation voltage aligns with safety regulations. Consider thermal management if operating near the upper temperature limit.

Part Context

The EL3022M belongs to Everlight's family of Triac output optocouplers designed for AC power switching. It serves as a bridge between low-voltage digital control signals and high-voltage AC loads. The device is commonly used in industrial and consumer electronics where galvanic isolation is necessary.

Replacement Considerations

Check for compatible alternatives such as the EL3022M(P5)-V. Verify pin compatibility and electrical specifications before substitution. Consult the manufacturer's cross-reference guide for approved replacements.
