IL4218-X017

Overview

The IL4218-X017 is a phototriac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a high isolation voltage of 5300 Vrms and an off-state voltage of 850 V. The device operates with a maximum continuous output current of 300 mA and supports a forward current of up to 60 mA. It utilizes a 6-DIP package with a width of 0.400 inches (10.16 mm). The component functions without a zero-crossing circuit and maintains a static dV/dt rating of 10 kV/µs. Operating temperatures range from -55°C to +100°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits.

Applications

• Solid-state relay control
• Motor drive isolation
• Power supply feedback loops

Procurement Notes

Verify the specific suffix X017 against official Vishay documentation to confirm pinout and packaging dimensions. Ensure compatibility with required isolation standards such as UL, VDE, or CSA before integration. Confirm that the non-zero-crossing characteristic aligns with the application's switching requirements.

Selection Notes

Select this component when high isolation voltage and robust noise immunity are required in triac control applications. The absence of a zero-crossing circuit allows for phase-angle firing control, making it suitable for dimming or speed control systems where precise timing is necessary rather than soft switching.

Part Context

This part belongs to the Vishay Triac & SCR Output Optocouplers category. It is designed for industrial applications requiring reliable galvanic isolation. The device integrates an infrared emitting diode with a phototriac detector on a single chip.

Replacement Considerations

Consult official Vishay substitution guides for direct replacements. Verify that any alternative component matches the 5300 Vrms isolation rating and 6-DIP package dimensions to ensure mechanical fit.
