IL4208-X007

Overview

The Vishay IL4208-X007 is a single-channel phototriac output optocoupler designed for high-speed applications. It features a low input current requirement and high dV/dt immunity, making it suitable for driving triacs and SCRs in noisy environments. The device provides an isolation voltage of 5300 Vrms and operates within a temperature range of -55°C to 100°C. It is available in surface-mount packaging with six pins.

Feature Summary

• High dV/dt immunity for reliable operation in noisy environments
• Low input current requirement for efficient drive capability
• Phototriac output configuration for direct AC load control

Applications

• Solid-state relays
• Motor control circuits
• Lighting control systems

Procurement Notes

Verify the specific suffix (X007) against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference certification marks such as UL, CSA, and VDE if required for end-product compliance. Confirm availability through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when high-speed switching and noise immunity are critical for triac or SCR gate driving. The low input current reduces power consumption in the control circuitry. Consider the surface-mount package for automated assembly processes. Evaluate thermal management requirements given the wide operating temperature range and potential heat dissipation in solid-state relay applications.

Part Context

This part belongs to the IL420 series of optocouplers from Vishay Semiconductor Opto Division. The series is characterized by its ability to handle high dv/dt rates, which prevents false triggering in AC power control applications. The IL4208 variant specifically offers a phototriac output, distinguishing it from logic-output variants like the IL420.

Replacement Considerations

Direct replacements may include other Vishay IL4208 variants with different suffixes indicating package or reel variations. Generic equivalents should be evaluated based on isolation voltage, forward current, and output characteristics. Verify pinout compatibility before substitution.
