FFA15U20DNTU

Diode Arrays Overview

The FFA15U20DNTU is an ultrafast recovery power rectifier manufactured by onsemi, originally developed by Fairchild Semiconductor. It features a dual common cathode configuration housed in a TO-3P package for through-hole mounting. Key electrical specifications include a peak repetitive reverse voltage of 200 V and an average rectified forward current of 15 A at a case temperature of 100°C. The device exhibits a maximum instantaneous forward voltage of 1.2 V at 15 A and 25°C, with a non-repetitive peak surge current capability of 150 A. Reverse recovery time is specified at 40 ns under standard test conditions.

Diode Arrays Procurement Notes

Verify component authenticity and datasheet revision status due to the transition from Fairchild Semiconductor to onsemi. Confirm that the specific ordering suffix matches the required packaging format. Ensure compliance with RoHS directives if applicable to the manufacturing lot. Check for any lifecycle notices regarding obsolescence or last-time buy notifications before finalizing procurement plans.

Diode Arrays Selection Notes

Select this component for designs requiring fast switching speeds and low reverse recovery charge. The TO-3P package provides robust thermal performance for high-current applications. Evaluate the 200 V rating against circuit voltage spikes to ensure adequate margin. Consider the 15 A continuous current limit relative to thermal management strategies and ambient operating temperatures.

Diode Arrays Part Context

This part belongs to the FFA series of ultrafast recovery rectifiers, designed for high-frequency power electronics. Originally released by Fairchild Semiconductor, the product line was integrated into onsemi's portfolio following corporate acquisition. The FFA15U20DNTU represents a specific variant within this family, optimized for general-purpose rectification tasks requiring rapid turn-off capabilities.

Diode Arrays Replacement Considerations

Consult official cross-reference lists for verified substitutes. Equivalent parts must match the 200 V reverse voltage, 15 A current rating, and TO-3P package dimensions. Verify that alternative components maintain similar reverse recovery times and forward voltage characteristics to ensure circuit compatibility.
