TIL114

Overview

The TIL114 is a single-channel optically coupled isolator manufactured by Isocom Components. It integrates an infrared light-emitting diode with an NPN silicon phototransistor featuring a base terminal for enhanced switching control. The device utilizes a 6-pin DIP through-hole package, providing robust physical mounting for industrial applications. Key electrical specifications include a minimum isolation voltage of 5300Vrms and a collector-emitter breakdown voltage of 30V. Typical response times are characterized by a rise time of 2µs and a fall time of 11µs. The unit operates within a temperature range of -55°C to 100°C.

Feature Summary

• Integrates an infrared LED with an NPN silicon phototransistor that includes a dedicated base terminal for improved switching performance and noise immunity.
• Provides high-voltage electrical isolation between input and output circuits using a dielectric barrier rated at 5300Vrms.
• Designed for through-hole mounting in a standard 6-pin dual in-line package (DIP) configuration.

Applications

• Industrial control systems requiring galvanic isolation
• Solid-state relay driver circuits
• Signal isolation in microprocessor-based interfaces

Procurement Notes

Verify the specific manufacturer designation when sourcing, as component availability may vary across distributors. Confirm that the 6-pin DIP package matches the target PCB footprint requirements. Ensure the operating temperature range aligns with the environmental conditions of the intended application. Cross-reference datasheet parameters such as isolation voltage and current transfer ratio against system design constraints before finalizing procurement.

Selection Notes

Select this component when a phototransistor output with a base terminal is required for faster switching or better linearity compared to standard configurations. Consider the 30V collector-emitter voltage limit to ensure compatibility with low-voltage logic loads. Evaluate the 6-pin package size against available board space. Verify that the 5300Vrms isolation rating meets safety standards for the specific circuit interface being protected.

Part Context

The TIL114 belongs to the TIL11x series of optocouplers from Isocom Components, which also includes variants like the TIL111, TIL116, and TIL117. These devices share a common architectural foundation of combining an infrared emitter with an NPN phototransistor. The series is designed for general-purpose isolation tasks where reliable signal transmission across electrically noisy environments is necessary.

Replacement Considerations

Compatible substitutes include other single-channel NPN phototransistor optocouplers with base terminals and similar isolation ratings, such as the PC817 series or HCPL-2630, provided pinout compatibility and voltage limits are verified.
