TCLT1114

Overview

The TCLT1114 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor with a base lead for enhanced switching performance and sensitivity. The device provides galvanic isolation of 5000Vrms between input and output circuits. Key electrical parameters include a collector-emitter voltage of 80V, a maximum forward current of 60mA, and a typical forward voltage of 1.6V. The package configuration is a 6-pin SOP (SOP-6L5).

Feature Summary

• Provides high-voltage galvanic isolation of 5000Vrms for safe signal transmission across potential differences.
• Integrates a phototransistor with a dedicated base terminal to facilitate faster switching speeds and improved control over saturation characteristics.

Applications

• Industrial automation systems requiring reliable signal isolation.
• Automotive electronic circuits demanding robust voltage separation.
• General-purpose digital communication interfaces needing noise immunity.

Procurement Notes

Verify the specific ordering suffix against the official Vishay datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets required safety certifications such as UL1577 or VDE standards for the intended application environment. Cross-reference the pinout diagram with the PCB footprint design to prevent installation errors during assembly.

Selection Notes

Select this component when high-speed switching is critical compared to standard transistor output couplers due to the base lead feature. Ensure the isolation voltage rating of 5000Vrms aligns with the system's safety requirements. Consider the SOP-6L5 package dimensions for space-constrained designs where through-hole alternatives are unsuitable.

Part Context

The TCLT1114 belongs to Vishay's family of transistor output optoisolators designed for general-purpose isolation applications. It complements other models in the series by offering a balance of speed and isolation strength. The inclusion of a base lead distinguishes it from basic phototransistor outputs, allowing for external biasing to optimize response times in high-frequency digital circuits.
