IL410-X008T

Overview

The IL410-X008T is a phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an integrated zero-crossing detection circuit and high dV/dt immunity, designed for reliable switching of AC loads. The device utilizes a 6-SMD surface-mount package and provides electrical isolation with a rated insulation voltage of 5300 Vrms. Key specifications include a low input forward current requirement and a triac output capable of handling standard AC line voltages. This component is engineered for applications requiring precise timing control and noise immunity in power switching environments.

Feature Summary

• Integrated zero-crossing detection circuitry for synchronized AC load switching
• High dV/dt immunity to prevent false triggering during rapid voltage transients
• Low input forward current requirement for efficient drive capability
• Surface-mount SMD-6 package design for compact board integration

Applications

• Solid-state relays (SSRs) for AC load control
• Motor speed controllers and soft-start circuits
• Lighting dimmers and phase-control systems
• Industrial AC power switching modules

Procurement Notes

Verify the specific suffix X008T against the manufacturer's latest datasheet to confirm packaging details and reel specifications. Ensure compatibility with your assembly process regarding the SMD-6 footprint. Cross-reference safety agency approvals such as UL or VDE if required for end-product certification. Confirm that the 5300 Vrms isolation rating meets your system's safety clearance requirements.

Selection Notes

Select this component when zero-crossing switching is mandatory to minimize electromagnetic interference and inrush current. The high dV/dt rating makes it suitable for noisy industrial environments where standard triac outputs might fail. Compare input current requirements against your microcontroller or driver capabilities. Ensure the thermal management plan supports the power dissipation characteristics within the SMD-6 package constraints.

Part Context

This part belongs to Vishay's IL410 series of phototriac optocouplers. The series is characterized by its integration of zero-crossing logic directly on the chip, distinguishing it from basic phototriac outputs. The X008T suffix typically denotes specific tape-and-reel packaging configurations used for automated surface-mount assembly processes.

Replacement Considerations

Check for direct equivalents like the IL4108-X007T which shares similar functional characteristics but may differ in packaging or specific electrical tolerances. Verify pinout compatibility before substitution. Ensure any replacement maintains the 5300 Vrms isolation rating and zero-crossing functionality.
