Overview
The IL4108-X009 is a phototriac output zero-crossing optocoupler manufactured by Vishay Semiconductor Opto Division. It features a gallium arsenide infrared LED coupled to a triac output with an integrated zero-crossing detection circuit. The device provides high isolation voltage of 5300 Vrms and supports surface mount installation in a 6-SMD package. Key electrical parameters include a maximum forward current of 60 mA, peak off-state voltage of 600 V, and maximum continuous output current of 300 mA. Operating temperature range spans from -55°C to +100°C.
Feature Summary
- Integrated zero-crossing detection circuit for reduced electromagnetic interference
- High common-mode transient immunity suitable for noisy environments
- Low input current requirement for efficient drive capability
Applications
- Solid-state relay driver circuits
- AC motor control systems
- Industrial process control interfaces
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging variants such as tape-and-reel options if available. Check for end-of-life notifications or discontinuance notices prior to final design approval to ensure long-term supply stability.
Selection Notes
Select this component when zero-crossing switching is required to minimize inrush currents and noise generation in AC loads. Ensure the load current does not exceed the 300 mA continuous rating. Verify that the system operating temperature remains within the specified -55°C to +100°C range for reliable performance.
Part Context
This part belongs to Vishay's IL410 series of phototriac output optocouplers designed for AC power switching applications. The series offers various isolation voltages and package configurations to meet diverse industrial requirements while maintaining consistent zero-crossing functionality.
Replacement Considerations
Consult official Vishay documentation for qualified alternative part numbers within the same product family. Verify pinout compatibility and electrical parameter equivalence before substitution.
