FFAF15U120DNTU

Diode Arrays Overview

The FFAF15U120DNTU is a fast recovery rectifier manufactured by onsemi, formerly Fairchild Semiconductor. It features a dual common cathode configuration housed in a TO-3PF package for through-hole mounting. The device supports a continuous forward current of 15 A and withstands a repetitive peak reverse voltage of 1200 V. Key electrical characteristics include a maximum forward voltage of 3.5 V, a reverse current of 20 uA, and a typical recovery time of 120 ns. It operates within a temperature range of -65°C to +150°C.

Diode Arrays Procurement Notes

Verify the manufacturer origin carefully, as this component was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm that the specific part number matches the required 15 A rating and TO-3PF package style. Ensure compliance with RoHS directives if applicable to your assembly process. Check for any specific handling requirements due to the through-hole leaded construction.

Diode Arrays Selection Notes

Select this component when a robust, high-voltage rectifier with moderate current capacity is required. The TO-3PF package offers superior heat dissipation compared to smaller surface-mount alternatives. Consider the 120 ns recovery time for efficiency in switching applications. Verify that the 1200 V rating aligns with the peak inverse voltage demands of the target circuit design.

Diode Arrays Part Context

This device belongs to the FFAF series of ultrafast recovery power rectifiers. The series includes variants with different current ratings, such as the 10 A and 20 A versions. These components are designed for demanding power electronics environments requiring reliable performance under high stress conditions.

Diode Arrays Replacement Considerations

Direct substitutes include the FFAF10U120DNTU (10 A) and FFAF20U120DNTU (20 A) from onsemi, provided current margins allow. Other manufacturers may offer equivalent TO-3PF dual common cathode rectifiers with matching 1200 V and 120 ns specifications.
