IL4118-X017

Overview

The IL4118-X017 is a phototriac output optocoupler featuring an aluminum gallium arsenide infrared LED optically coupled to a photosensitive zero-crossing TRIAC network. It provides 5300Vrms isolation voltage and operates with a typical forward voltage of 1.3V. The device includes a hold current specification up to 200µA and requires a trigger current of 1.3mA for activation. Packaged in a 6-DIP configuration, it supports RoHS compliance standards.

Feature Summary

• Integrates an AlGaAs IR LED with a photosensitive zero-crossing TRIAC network for precise timing control
• Provides high-voltage isolation capability rated at 5.3kVrms between input and output circuits
• Features built-in zero-crossing detection to minimize electromagnetic interference during switching

Applications

• Solid-state relay driver circuits
• Zero-voltage switching power supplies
• Industrial motor control systems

Procurement Notes

Verify the specific suffix -X017 against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives if required by your manufacturing process. Cross-reference the trigger current and hold current parameters with your circuit design requirements before finalizing procurement.

Selection Notes

Select this component when zero-crossing detection is critical for reducing electrical noise in AC load control applications. The 5.3kVrms isolation rating suits high-voltage industrial environments. Consider the 1.3mA trigger current requirement to ensure adequate drive strength from the controlling logic interface.

Part Context

This part belongs to the IL411x series of optoisolators designed for AC power control. It shares architectural similarities with the IL4116 and IL4117 but distinguishes itself through specific zero-crossing characteristics and packaging options tailored for surface mount or through-hole integration depending on the suffix.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and isolation voltage ratings if considering alternative manufacturers' zero-crossing triac optocouplers.
