Overview
The IL4108-X007 is a phototriac output optocoupler featuring an integrated zero-crossing detection circuit and high dv/dt immunity. It provides electrical isolation with a rated isolation voltage of 5300 Vrms. The device operates with a maximum forward current of 60 mA and a typical forward voltage of 1.16 V. It supports an output voltage of up to 800 V and dissipates 500 mW of power. The component is available in surface-mount packaging.
Feature Summary
- Integrated zero-crossing detection circuit for precise AC switching control
- High dv/dt immunity to prevent false triggering during rapid voltage changes
- Phototriac output designed for direct drive of triacs and SCRs
Applications
- Solid-state relay (SSR) driver circuits
- AC motor speed control systems
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required isolation voltage ratings for the target safety application. Cross-reference datasheet revision dates to confirm compliance with current regulatory standards.
Selection Notes
Select this component when zero-crossing switching is required to minimize electromagnetic interference and inrush currents. The high dv/dt rating makes it suitable for noisy industrial environments. Verify that the load current remains within the phototriac's continuous and surge current limits defined in the electrical characteristics table.
Part Context
This part belongs to Vishay’s family of phototriac output optocouplers. It shares functional similarities with other models like the IL4108-X007T, differing primarily in packaging or reel configuration. These devices are engineered for reliable isolation in AC power control applications requiring low input current drive.
Replacement Considerations
Direct substitutes may include other Vishay phototriac optocouplers with matching zero-crossing features. Verify pinout compatibility and isolation voltage ratings before substitution. Consult official replacement lists for qualified equivalents.
