IL4116

Overview

The IL4116 is a zero-crossing phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates a GaAs infrared LED with a photosensitive thyristor system featuring integrated noise suppression. The device provides an isolation voltage of 5300Vrms and supports a maximum output voltage of 400V. It operates within a temperature range of -40°C to 100°C and is available in a 6-DIP package.

Feature Summary

• Integrated zero-crossing detection for low electromagnetic interference switching
• High isolation voltage capability for safety-critical applications
• Built-in noise suppression to prevent false triggering

Applications

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

Procurement Notes

Verify the specific suffix (e.g., X007T) against the datasheet to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required isolation voltage and package type for the target design. Cross-reference RoHS compliance status with current manufacturing notices.

Selection Notes

Select this component when zero-crossing switching is required to minimize electrical noise and inrush current. The integrated noise suppression makes it suitable for noisy industrial environments. Verify that the input forward current requirements align with the driving circuit capabilities.

Part Context

The IL4116 belongs to a family of optically coupled GaAs IRLEDs paired with photosensitive thyristors. This series is designed for AC power control applications where precise timing and noise immunity are essential. It serves as a robust interface between low-voltage logic circuits and high-voltage AC loads.

Replacement Considerations

Check for direct pin-compatible alternatives such as the IL4117 or IL4118 if different isolation ratings or package options are needed. Verify that substitute components maintain the same zero-crossing functionality and noise suppression characteristics.
