TIL186-1

Overview

The TIL186-1 is an AC-input optocoupler manufactured by Texas Instruments, designed for applications requiring high-voltage isolation between input and output circuits. It features a Darlington transistor output configuration, providing high current transfer ratio suitable for direct interface with logic inputs. The device utilizes an infrared LED coupled to a photodetector within a single package.

Feature Summary

High-voltage isolation capability between input and output sections
AC input signal compatibility without external rectification
Darlington transistor output for high gain

Applications

AC input signal detection in industrial control systems
Isolation interfaces for microprocessor-based systems
Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix designation to ensure correct pinout and electrical characteristics. Confirm that the Darlington output type matches the load requirements of the target application. Check for automotive or extended temperature variants if operating conditions exceed standard industrial ranges.

Selection Notes

Select this component when AC voltage sensing is required without additional rectifier components. Ensure the isolation voltage rating meets system safety standards. Consider the output saturation voltage and current transfer ratio when driving downstream logic or relay coils directly.

Part Context

This part belongs to the family of AC-input optocouplers from Texas Instruments. These devices are engineered to simplify circuit design by integrating rectification functionality within the optocoupler structure, reducing component count compared to discrete solutions using standard DC-input optocouplers.
