UFR3020R

Single Diodes Overview

The UFR3020R is a fast recovery rectifier manufactured by Microchip Technology, designed for high-speed switching applications. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 30 A. The device exhibits a typical reverse recovery time of 35 ns and a maximum non-repetitive surge current capability of 500 A. Operating junction temperatures range from -65°C to +175°C, with a specified maximum reverse leakage current of 15 µA at rated voltage.

Single Diodes Feature Summary

• Fast recovery characteristics suitable for high-frequency power conversion
• High thermal stability supporting extended operating temperature ranges
• Robust surge current handling capability for transient protection

Single Diodes Applications

• High-frequency DC-DC converters
• Free-wheeling diodes in motor drives
• Isolated output rectification in switch-mode power supplies

Single Diodes Procurement Notes

Verify the specific suffix 'R' against official Microchip documentation to confirm tray packaging requirements. Ensure compatibility with existing board layouts for the DO-4 package. Confirm RoHS status as this series may not be compliant. Validate lead times directly with authorized distributors due to potential supply chain variability.

Single Diodes Selection Notes

Select this component when a 200 V rating and 30 A continuous current are required in a through-hole configuration. Compare the 35 ns recovery time against circuit switching frequencies to minimize reverse recovery losses. Ensure the DO-4 package fits the mechanical constraints of the target assembly.

Single Diodes Part Context

This part belongs to the UFR/FRR family of fast recovery rectifiers from Microchip Technology. It shares electrical specifications with the standard UFR3020 but differs in packaging format. The family is characterized by low reverse recovery charge and high thermal performance for industrial power electronics.

Single Diodes Replacement Considerations

Direct substitutes include the UFR3020 (bulk packaging) or UT3020 if available. Verify pinout compatibility and thermal resistance values before substitution. Cross-reference datasheets for exact reverse recovery time variations.
