FOD4116TV

Triac, SCR Output Optoisolators Overview

The FOD4116TV is a zero-crossing triac driver optoisolator manufactured by Fairchild Semiconductor. It integrates an infrared LED with a triac output stage to provide high-voltage isolation between control and load circuits. The device features a 5000 Vrms insulation voltage rating and operates within a temperature range of -25°C to 85°C. Packaged in a standard 6-pin DIP configuration, it is designed for applications requiring precise timing and noise immunity in AC power switching systems.

Triac, SCR Output Optoisolators Feature Summary

• Zero-crossing detection capability ensures triac triggering occurs at the AC voltage zero point to minimize electromagnetic interference.
• High isolation voltage rating provides robust electrical separation between low-voltage control logic and high-voltage AC loads.
• Integrated triac output stage simplifies circuit design by eliminating the need for external discrete switching components.

Triac, SCR Output Optoisolators Applications

• Solid-state relay (SSR) input stages
• AC motor speed control circuits
• Lighting dimmer switch interfaces

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package marking matches the specific suffix TV for tape-and-reel packaging if applicable. Check datasheet revisions for any updates to mechanical dimensions or thermal characteristics prior to integration into final assembly designs.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce electrical noise in AC line applications. Ensure the load current does not exceed the internal triac ratings. Consider the 6-pin DIP package constraints for PCB layout. Verify that the control side voltage levels are compatible with the integrated infrared LED forward voltage requirements.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FOD411x family of zero-crossing triac drivers from Fairchild Semiconductor. The series includes variants such as the FOD4116 and FOD4118, which share similar functional architectures but may differ in specific electrical parameters or packaging options. These devices are widely used in industrial and consumer AC power control applications.

Triac, SCR Output Optoisolators Replacement Considerations

Check for equivalent zero-crossing triac drivers from other manufacturers. Verify pinout compatibility and insulation voltage ratings before substitution. Note that some datasheets indicate this product line may be obsolete; confirm availability and lifecycle status with suppliers.
