16CTU04S

Overview

The Vishay 16CTU04S is an ultrafast rectifier featuring a dual common-cathode configuration within a D2PAK package. It utilizes FRED Pt technology to deliver optimized forward voltage drop and rapid recovery characteristics. The device supports a peak repetitive reverse voltage of 400 V and provides an average rectified forward current of 8 A per leg. Key electrical parameters include a maximum reverse recovery time of 60 ns, a typical forward voltage of 1.3 V at 8 A, and a junction temperature range extending up to 175 °C.

Feature Summary

• FRED Pt platinum-doped lifetime control ensures high ruggedness and reliability
• Ultrafast recovery time minimizes switching losses and over-dissipation
• Planar structure design guarantees low leakage current and low forward voltage drop

Applications

• Output rectification stage of switch-mode power supplies (SMPS)
• Uninterruptible power supply (UPS) systems
• DC-to-DC converters
• Freewheeling diodes in low voltage inverters
• Chopper motor drives

Procurement Notes

Verify the specific ordering suffix to confirm the required packaging format, such as tube or tape and reel orientation. Confirm lead-free status if RoHS compliance is mandatory for the assembly process. Ensure thermal management requirements align with the specified junction-to-case thermal resistance values during system integration.

Selection Notes

Select this component for applications requiring fast switching speeds and high efficiency in power conversion circuits. The D2PAK package offers robust mechanical mounting suitable for heatsink attachment. Consider the 175 °C operating temperature rating for environments demanding higher thermal margins compared to standard silicon rectifiers.

Part Context

This part belongs to the Vishay FRED Pt series of ultrafast recovery rectifiers. It shares core semiconductor technology with the TO-262 packaged variant, designated as 16CTU04-1. Both models utilize identical internal die specifications but differ in external casing styles to accommodate different board layout and thermal dissipation strategies.

Replacement Considerations

The 16CTU04-1 serves as the direct functional equivalent utilizing the TO-262 case style instead of the D2PAK footprint.
