IL4116-X009T

Overview

The IL4116-X009T is a single-channel phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an integrated zero-crossing detection circuit for precise AC load control. The device utilizes a gallium arsenide infrared-emitting diode optically coupled to a phototriac within a surface-mount package. Key electrical specifications include a maximum continuous output current of 300 mA, a peak off-state voltage (VDRM) of 600 V, and a high isolation voltage rating of 5300 Vrms. It operates within a temperature range of -55°C to +100°C.

Feature Summary

• Integrated zero-crossing detection circuitry for synchronized AC switching
• High isolation voltage capability for safe signal transfer
• Phototriac output designed for direct AC load driving

Applications

• Solid-state relay (SSR) modules
• AC motor speed control circuits
• Lighting dimmer applications

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm pinout and packaging details. Ensure the selected variant matches the required thermal management and isolation standards for the target application environment.

Selection Notes

Select this component when zero-crossing switching is required to minimize electromagnetic interference in AC systems. Confirm that the 600 V blocking voltage and 300 mA current ratings exceed the peak loads expected in the circuit design.

Part Context

This part belongs to Vishay's IL series of triac output optocouplers. These devices are engineered for industrial applications requiring robust galvanic isolation between low-voltage control logic and high-voltage AC power stages.

Replacement Considerations

IL410-X009T: Similar triac output with zero-crossing but different internal configuration.
