FOD4116T

Triac, SCR Output Optoisolators Overview

The FOD4116T is a single-channel Triac output optoisolator manufactured by onsemi. It provides 5000Vrms isolation voltage between input and output. The device features an internal zero-crossing detection circuit for low electromagnetic interference switching. Key electrical parameters include a maximum DC forward current of 30 mA, a typical forward voltage of 1.25 V, and a peak off-state voltage of 600 V. It operates within a temperature range of -55°C to 100°C and is housed in a 6-DIP package.

Triac, SCR Output Optoisolators Feature Summary

• Integrated zero-crossing detection circuitry for noise-immune AC load control
• High isolation voltage rating of 5000Vrms for safety compliance
• Robust static dV/dt rating of 10kV/µs to prevent false triggering

Triac, SCR Output Optoisolators Applications

• Solid-state relays (SSRs)
• AC motor control circuits
• General-purpose AC load switching

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required packaging configuration. Check for RoHS compliance documentation and material declarations. Ensure storage conditions adhere to moisture sensitivity level requirements prior to assembly.

Triac, SCR Output Optoisolators Selection Notes

Select this component when high-voltage isolation and precise timing are required for AC loads. The integrated zero-crossing feature reduces electrical noise compared to random-phase devices. Consider the 600V peak off-state voltage limit for appropriate circuit design margins. Evaluate thermal management requirements based on the specified operating temperature range.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FOD410/4108/4116/4118 series of Triac output optoisolators. It shares functional similarities with the FOD4118T but differs in peak off-state voltage specifications. The series is designed for industrial applications requiring reliable galvanic isolation between control logic and high-voltage AC lines.

Triac, SCR Output Optoisolators Replacement Considerations

The FOD4116TV is a verified active substitute from onsemi. Verify pinout compatibility and ensure the replacement meets the same isolation voltage and current ratings.
