TIL113S(TB)-V

Overview

The TIL113S(TB)-V is a single-channel photodarlington output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode and a photodarlington transistor within a surface-mount package to provide electrical isolation between input and output circuits. The device features a high isolation voltage of 5000 Vrms, ensuring robust safety standards for signal transmission. Key electrical parameters include a typical current transfer ratio of 300% at a forward current of 10 mA, a maximum DC forward current of 60 mA, and a dark current maximum of 100 nA. It operates within a temperature range of -55°C to +100°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using an infrared LED and photodarlington transistor configuration.
• Features a high current transfer ratio to ensure efficient signal transmission with low input drive requirements.
• Offers high insulation voltage capability to protect sensitive electronics from high voltage transients.

Applications

• Digital logic signal transmission and level shifting
• Power supply control and switching circuits
• Electrical isolation between different circuit systems

Procurement Notes

Verify the specific suffix designation against official Everlight documentation to confirm pinout and packaging variations. Confirm RoHS compliance status through the manufacturer's latest environmental reports. Ensure the selected variant matches the required surface mount footprint for PCB integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when high current transfer efficiency is required for driving loads directly. Consider the operating temperature range if deployed in extreme environments. Evaluate the isolation voltage requirements against system safety standards. Compare package dimensions against available board space constraints before finalizing the design.

Part Context

This component belongs to the family of transistor output optocouplers designed for general-purpose isolation applications. It serves as a bridge for transferring digital signals across isolated boundaries while maintaining electrical safety. The photodarlington output structure provides higher gain compared to standard phototransistor variants, making it suitable for applications requiring significant output current from minimal input drive.

Replacement Considerations
