16CTQ080

Overview

The Vishay 16CTQ080 is a Schottky rectifier featuring a center tap configuration with two independent anodes and a common cathode. It provides a maximum average forward current of 16 A (8 A per leg) and a maximum DC reverse voltage of 80 V. The device utilizes silicon technology in a TO-220AB package, supporting junction temperatures from -55 °C to 175 °C. Key electrical characteristics include a maximum forward voltage drop of 0.72 V at 8 A and 25 °C, and a peak non-repetitive surge current capability of 850 A.

Feature Summary

• Center tap configuration with dual anodes and a common cathode for efficient power conversion
• Proprietary barrier technology optimized for low reverse leakage current at elevated temperatures
• Guard ring structure designed to enhance ruggedness and ensure long-term reliability
• High purity, high temperature epoxy encapsulation providing enhanced mechanical strength and moisture resistance

Applications

• Switching power supplies
• DC-DC converters
• Freewheeling diodes
• Reverse battery protection circuits

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard production version lacks lead-free certification, while the PbF suffix indicates compliance with RoHS standards. Confirm the package style matches the required mounting specifications. Ensure the voltage rating aligns with the system's peak reverse voltage requirements before procurement.

Selection Notes

Select this component for applications requiring high-frequency operation and low forward voltage drop. The TO-220AB package facilitates flange mounting for effective thermal management. Consider the thermal resistance values when designing heatsinking solutions. Verify that the operating junction temperature remains within the specified range during continuous duty cycles.

Part Context

This device belongs to the Vishay 16CTQ series of Schottky rectifiers. The series includes variants with different voltage ratings, such as 60 V and 100 V options. All models share the same physical package and general structural features. The series is designed for industrial level qualification and high-power applications.

Replacement Considerations

Direct substitutes within the same series include the 16CTQ060 and 16CTQ100. These parts share identical current ratings and package dimensions but differ in maximum reverse voltage. Ensure the replacement voltage rating meets or exceeds the original circuit requirements.
