TIL111

Overview

The TIL111 is a single-channel optocoupler featuring an infrared LED coupled to an NPN silicon phototransistor with a base terminal. It provides 5300Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. The device supports a maximum forward current of 60mA and offers a minimum current transfer ratio of 20%. Packaged in a 6-pin DIP through-hole configuration, it is designed for robust signal transmission across isolated circuits.

Feature Summary

• Integrates an infrared emitting diode with an NPN silicon phototransistor output stage
• Provides high-voltage electrical isolation between input and output circuits
• Includes a dedicated base terminal on the phototransistor for enhanced switching control

Applications

• General-purpose digital signal isolation
• Microprocessor interface circuits
• Solid-state relay driver applications

Procurement Notes

Verify the specific manufacturer part number against official Isocom Components documentation to ensure authenticity. Confirm that the package style matches the required 6-pin DIP form factor. Check datasheet specifications for current transfer ratio and isolation voltage ratings prior to integration into final designs.

Selection Notes

Select this component when a phototransistor output with a base pin is required for improved noise immunity or faster switching speeds compared to standard configurations. Ensure the application voltage does not exceed the collector-emitter rating and that the isolation requirements are met by the 5300Vrms specification.
