IL4116-X009

Overview

The IL4116-X009 is a phototriac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a single channel with an isolation voltage of 5300Vrms and operates within a temperature range of -55°C to +100°C. The device utilizes a surface-mount 6-SMD, gull wing package. Key electrical characteristics include a maximum forward current of 60 mA, a typical forward voltage of 1.3 V, and a peak repetitive off-state voltage of 850 V. The component supports a maximum continuous output current of 300 mA and includes a zero-crossing circuit for precise switching applications.

Feature Summary

• Integrated zero-crossing detection circuitry for reduced electromagnetic interference during AC switching
• High-voltage insulation capability rated at 5300Vrms between input and output sections
• Phototriac output stage designed for direct control of triac or SCR gates in power circuits

Applications

• Solid-state relay (SSR) driver circuits
• AC motor speed control systems
• Lighting dimmer modules

Procurement Notes

Verify the obsolete status of this specific part number before initiating procurement processes. Confirm availability through authorized distributors or secondary market suppliers, as original manufacturing may have ceased. Ensure that any substitute components meet the required isolation voltage and zero-crossing specifications to maintain system safety and performance integrity.

Selection Notes

Select this component for applications requiring galvanic isolation with synchronized AC switching. The zero-crossing feature minimizes electrical noise and stress on connected loads. Consider the 6-SMD package constraints for PCB layout. Evaluate thermal management requirements given the 500 mW power dissipation rating under operating conditions.

Part Context

This device belongs to Vishay's family of phototriac output optoisolators. It shares functional similarities with the IL4118-X009T but differs in packaging and specific electrical ratings. The series is designed for industrial and consumer AC power control applications where high isolation voltage and low input current are critical design parameters.

Replacement Considerations

The IL4116-X009 is listed as obsolete. Potential substitutes include the IL4118-X009T, which offers similar zero-crossing functionality but in a tape-and-reel package. Verify pin compatibility and electrical limits when considering alternative parts from the same manufacturer or other vendors.
