TIL111S(TA)

Overview

The TIL111S(TA) is a transistor output optocoupler manufactured by Everlight Electronics. It features a single channel with an NPN phototransistor output and provides 5000 Vrms isolation voltage. The device utilizes a surface mount package configuration, specifically identified as 6-SMD in distributor listings, though datasheet references also mention 6-pin DIP variants for the broader TIL111 series. Key electrical parameters include a forward voltage of approximately 1.5V and a fall time of 100 ns. The component is designed for applications requiring high-speed logic output or general signal isolation.

Feature Summary

• Provides galvanic isolation between input and output circuits
• Features a transistor output type with base connection
• Compatible with automatic placement equipment via tape packaging
• Supports infrared and vapor phase reflow solder processes

Applications

• Industrial control systems for signal isolation
• Telecommunication equipment interface circuits
• Microprocessor system input/output isolation
• Switching power supply feedback loops

Procurement Notes

Verify the specific suffix designation (TA vs TB vs V) against the current manufacturer datasheet to confirm pinout and packaging details. Confirm availability status as some distributors list this part as discontinued or limited stock. Ensure the selected variant matches the required isolation voltage and output type specifications for the target application circuit design.

Selection Notes

Select this component when a low-cost, single-channel optocoupler with transistor output is required. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the package type compatibility with the PCB layout, noting discrepancies between SMD and DIP descriptions in various sources. Verify the operating temperature range requirements against the standard industrial limits defined in the official technical data sheet.
