IL420-X009T

Overview

The IL420-X009T is a high-voltage, high-speed phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with a Triac output and operates without an integrated zero-crossing circuit. The device provides robust electrical isolation of 5300Vrms between input and output terminals. It supports a maximum forward current of 60mA for the LED input and handles a RMS on-state current of 300mA at the output. The component is designed for operation within a temperature range of -55°C to 100°C.

Feature Summary

• High voltage isolation capability of 5300Vrms ensures safe separation between control and power circuits.
• Fast switching performance with a turn-on time of 35µs and minimum static dV/dt of 10kV/µs.
• Low input trigger current requirement of 2mA maximizes for efficient drive from logic interfaces.
• Wide operating temperature range allows reliable function in extreme thermal environments.

Applications

• Solid state relays requiring high isolation and fast response
• Motor control circuits for AC load switching
• Industrial automation systems utilizing triac-based outputs

Procurement Notes

Verify the specific suffix X009T against official Vishay documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required isolation standards such as UL or VDE if applicable to your design. Cross-reference datasheet parameters like holding current and breakover voltage against system requirements before finalizing procurement decisions.

Selection Notes

Select this component when high dv/dt immunity and rapid triac triggering are critical. The absence of a zero-crossing feature makes it suitable for phase-control applications rather than noise-sensitive switching. Evaluate the 300mA RMS output capacity against load requirements and ensure adequate heat dissipation for continuous operation within the specified temperature limits.

Part Context

This part belongs to the IL420 series of phototriac optocouplers. It shares core architectural similarities with other variants in the family but differs in packaging and reel configuration due to the X009T designation. The series is recognized for its reliability in industrial environments where high voltage isolation and speed are prioritized over zero-crossing precision.

Replacement Considerations

Direct substitutes include IL420-X009 and IL420GI I. Verify pinout compatibility and exact electrical parameter matches for all replacement candidates. Consult Vishay PCN documents for any recent manufacturing changes affecting form, fit, or function.
