SSUR3140R

Single Diodes Overview

The SSUR3140R is a high-performance ultra-fast rectifier diode manufactured by Microsemi Corporation. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 30 A. The device utilizes a stud mount configuration within the DO-203AA (DO-4) package, facilitating efficient thermal dissipation for power applications. Its switching characteristics are optimized with a recovery time of less than 100 ns, ensuring minimal energy loss during rapid transitions.

Single Diodes Feature Summary

• Ultra-fast recovery characteristics with reverse recovery time under 100 ns
• Robust stud mount construction in DO-203AA package for reliable thermal management
• High surge current capability designed for demanding power conversion environments

Single Diodes Applications

• High-frequency DC-DC converters
• Industrial motor drive circuits
• Uninterruptible power supply (UPS) systems

Single Diodes Procurement Notes

Verify the manufacturer marking on the component body to confirm it matches Microsemi Corporation specifications. Ensure the part number suffix 'R' corresponds to the specific reel or tape-and-reel packaging variant if required by your assembly process. Cross-reference the datasheet revision date to ensure compatibility with your design's electrical constraints.

Single Diodes Selection Notes

Select this component when designing circuits requiring fast switching speeds and high current handling in a stud-mount form factor. The 400 V rating suits medium-voltage AC-DC conversion stages. Consider the thermal resistance of the mounting interface, as the stud mount relies heavily on the heatsink connection for maintaining junction temperature limits during continuous operation.

Single Diodes Part Context

This device belongs to the SSUR3140 series of ultra-fast rectifiers from Microsemi. The series includes variants such as the SSUR3160, offering different voltage ratings while maintaining similar current and speed characteristics. These components are engineered for silicon power rectification in industrial and commercial power electronics.

Single Diodes Replacement Considerations

Direct substitutes include other 30 A, 400 V ultra-fast diodes in stud mount packages. Verify that replacement parts meet the same reverse recovery time specification of less than 100 ns to maintain circuit efficiency.
