IL4118-X007

Overview

The IL4118-X007 is a phototriac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a 5300Vrms isolation voltage and integrates a zero-crossing detection circuit for precise AC switching control. The device utilizes a surface-mount 6-SMD package and supports an operating temperature range from -55°C to 100°C. Key electrical specifications include a maximum DC forward current of 60 mA, a typical forward voltage of 1.3V, and a blocking voltage of 800 V. It is designed for applications requiring high dv/dt immunity and reliable triac triggering.

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm pinout and packaging variations. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference datasheet parameters such as holding current and trigger current with your target application requirements before finalizing procurement decisions.

Selection Notes

Select this component when zero-crossing functionality is mandatory to minimize inrush currents and electromagnetic interference. Compare the 6-SMD footprint against available board space constraints. Evaluate the 800 V blocking voltage against peak line voltages to ensure adequate safety margins for your specific AC mains or industrial power environment.

Part Context

This part belongs to the IL4118 family of phototriac optocouplers. It serves as a surface-mount alternative to through-hole variants like the IL4118-X007. The device shares architectural similarities with other Vishay isolation products but is distinctively characterized by its integrated zero-crossing detector and high dv/dt rating.
