FFA05U120DNTU

Diode Arrays Overview

The FFA05U120DNTU is a fast recovery rectifier manufactured by onsemi, formerly Fairchild Semiconductor. It features a dual common cathode configuration housed in a TO-3P package for through-hole mounting. The device supports a maximum repetitive peak reverse voltage of 1200 V and an average forward current of 5 A. Key electrical parameters include a forward voltage of 3.5 V at rated current, a reverse leakage current of 10 uA, and a maximum surge current of 60 A. The unit operates within a temperature range of -65 °C to +150 °C with a typical recovery time of 100 ns.

Diode Arrays Feature Summary

• Dual common cathode configuration for bridge or push-pull applications
• Fast recovery characteristics suitable for high-frequency switching
• High thermal stability with extended operating temperature range

Diode Arrays Applications

• High-voltage power supply circuits
• Industrial motor drives
• Uninterruptible power supplies (UPS)

Diode Arrays Procurement Notes

Verify the manufacturer designation as onsemi, resulting from the acquisition of Fairchild Semiconductor. Confirm the specific suffix DNTU corresponds to the tube packaging format. Ensure compatibility with existing TO-3P mounting hardware and verify RoHS compliance status against current datasheets before integration into production designs.

Diode Arrays Selection Notes

Select this component when a robust, high-voltage rectifier with moderate current capacity is required. The TO-3P package provides superior heat dissipation compared to smaller surface-mount alternatives. Consider the 1200 V rating for safety margins in mains-connected systems and evaluate the 100 ns recovery time against the specific switching frequency requirements of the target application circuit.

Diode Arrays Part Context

This part belongs to the FFA series of ultrafast recovery diodes designed for demanding power electronics environments. The series utilizes planar passivation technology to ensure reliability under high thermal stress. The transition from Fairchild branding to onsemi reflects corporate restructuring while maintaining established product specifications and manufacturing standards for industrial-grade semiconductor components.

Diode Arrays Replacement Considerations

Consult official cross-reference lists for equivalents such as the FFA10U120DNTU for higher current handling or the FFA05U120DTU if tape-and-reel packaging is preferred. Verify pinout compatibility and thermal resistance values before substituting to ensure system performance remains within design limits.
