FFA10U40DNTU

Diode Arrays Overview

The FFA10U40DNTU is a fast recovery rectifier manufactured by Fairchild Semiconductor, now part of onsemi. It features a dual common cathode configuration housed in a TO-3P package for through-hole mounting. The device supports a continuous forward current of 10 A and withstands a repetitive peak reverse voltage of 400 V. Key electrical characteristics include a maximum forward voltage of 3.5 V, a reverse leakage current of 10 uA, and a typical reverse recovery time of 100 ns. It operates within a temperature range of -65°C to +150°C junction temperature.

Diode Arrays Procurement Notes

Verify the manufacturer status carefully as Fairchild Semiconductor was acquired by onsemi. Confirm that the specific part number matches the required pinout and package dimensions for your PCB layout. Check for any recent product change notifications regarding material composition or manufacturing location changes that may affect compliance or performance specifications.

Diode Arrays Selection Notes

Select this component when a dual diode arrangement is required in a single package to save board space. Ensure the circuit design accounts for the 100 ns reverse recovery time to minimize switching losses. Verify that the thermal management solution can handle the power dissipation at the specified 10 A load within the allowed junction temperature limits.

Diode Arrays Part Context

This component belongs to the FFA series of ultra-fast recovery power rectifiers. These devices are designed for use in high-efficiency power conversion applications where low reverse recovery charge is critical. The TO-3P package provides robust mechanical mounting and efficient heat dissipation capabilities compared to smaller surface-mount alternatives.

Diode Arrays Replacement Considerations

Check for equivalents such as the FFPF10U40DNTU from onsemi, ensuring package compatibility. Verify that any substitute maintains the same dual common cathode configuration and meets the 400V/10A ratings.
