6TQ045

Overview

The Vishay 6TQ045 is a Schottky rectifier in the 6TQ series, rated for a maximum DC reverse voltage of 45 V and an average forward current of 6 A. It utilizes proprietary barrier technology to ensure low reverse leakage at high temperatures, supporting junction operation up to 175 °C. The device features a TO-220AC package with the case connected to the cathode. Key electrical characteristics include a maximum forward voltage drop of 0.60 V at 6 A and 25 °C, and a peak non-repetitive surge current capability of 690 A.

Feature Summary

• Optimized for low reverse leakage current at elevated temperatures using proprietary barrier technology

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the ordering suffix matches the required lead-free specification (PbF) if applicable. Review the official datasheet for thermal management requirements and mounting torque specifications to ensure proper installation and operational safety within the specified temperature range.

Selection Notes

Select this component when designing circuits requiring high-frequency operation and low forward voltage drop. Ensure the application operates within the 45 V reverse voltage limit and 6 A average current rating. Consider the thermal resistance from junction to case for heatsink design, particularly for duty cycles exceeding 50 percent. Verify compatibility with the TO-220AC footprint and cathode-connected base configuration.

Part Context

The 6TQ045 belongs to the Vishay 6TQ... Schottky Rectifier series, which includes variants with 35 V and 40 V ratings. These devices are manufactured by Vishay High Power Products and are housed in the TO-220AC package. The series is engineered for robust performance in industrial environments, offering high reliability through specialized encapsulation and guard ring technologies.

Replacement Considerations

Direct substitutes within the same series include the 6TQ035 and 6TQ040, which share identical current ratings and packaging but differ in reverse voltage capabilities. When replacing, verify that the circuit's peak reverse voltage requirements align with the substitute's rating.
