FFAF05U120DNTU

Diode Arrays Overview

The FFAF05U120DNTU is an ultra-fast recovery power rectifier manufactured by onsemi, formerly Fairchild Semiconductor. It features a dual common cathode configuration housed in a TO-3PF package. The device supports a peak repetitive reverse voltage of 1200 V and an average forward current of 5 A at a case temperature of 100°C. Key electrical characteristics include a maximum instantaneous forward voltage of 3.5 V at 5 A and 25°C, a non-repetitive peak surge current of 30 A, and a maximum reverse recovery time of 100 ns. The component operates within a junction temperature range of -65°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix 'TU' against official documentation to confirm tape-and-reel packaging details, as datasheets may reference standard tube packaging. Confirm RoHS compliance status through current manufacturer declarations. Check for obsolescence notices or lifecycle changes, as the original manufacturer was acquired. Ensure thermal management designs account for the specified junction-to-case thermal resistance.

Diode Arrays Selection Notes

Select this component for applications requiring fast switching speeds and high voltage isolation. Evaluate thermal constraints carefully, as the 5 A rating is dependent on maintaining the case temperature at 100°C or lower. Consider the TO-3PF package dimensions for mechanical fit. Compare reverse recovery characteristics against circuit requirements to ensure compatibility with high-frequency operation without excessive switching losses.

Diode Arrays Part Context

This part belongs to the FFAF series of ultra-fast recovery power rectifiers originally developed by Fairchild Semiconductor. The series is designed for high-efficiency power conversion applications. The TO-3PF package provides robust mounting capabilities for industrial environments. The product line has transitioned under onsemi following corporate acquisitions, maintaining the original technical specifications.
