1N5806USE3/TR

Overview

The Microchip Technology 1N5806USE3/TR is a single fast recovery rectifier designed for surface mount applications. It features a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current of 2.5 A. The device exhibits a low forward voltage drop of 975 mV at the rated current and a rapid reverse recovery time of 25 ns. It operates within a junction temperature range of -65 °C to +175 °C and has a maximum surge current rating of 35 A.

Feature Summary

• Ultrafast switching capability with minimal reverse recovery time for high-frequency efficiency
• Low leakage current in the off-state to reduce power loss
• Hermetic-free lead-free construction compliant with environmental standards
• Robust thermal performance suitable for high-temperature environments

Applications

• Secondary ultrafast rectification in switch-mode power supplies
• Free-wheeling diode circuits in DC-to-DC converters
• Reverse polarity protection in electronic systems
• High-frequency chopper drive applications

Procurement Notes

Verify the specific suffix 'USE3/TR' to confirm the lead-free status and tape-and-reel packaging format. Ensure the order quantity aligns with the manufacturer's standard reel size requirements. Cross-reference the datasheet revision date to confirm compliance with current RoHS directives. Confirm that the D-5A-2 package footprint matches the target PCB design constraints before finalizing procurement.

Selection Notes

Select this component when a surface mount fast recovery rectifier is required with a 150 V blocking voltage and 2.5 A continuous current capacity. It is appropriate for designs prioritizing low reverse recovery charge and high thermal stability. Consider the D-5A-2 package dimensions for layout compatibility. This part serves as a direct replacement for through-hole variants where space savings and automated assembly are necessary.

Part Context

This device belongs to the 1N5806 series of ultrafast rectifiers manufactured by Microchip Technology. It shares electrical characteristics with other members of the family but differs in package type and mounting style. The series is engineered for reliability in harsh environments, offering superior performance compared to standard recovery diodes. It is widely used in industrial and commercial power conversion equipment requiring compact form factors.

Replacement Considerations

The 1N5806U is a compatible surface mount alternative within the same product family. Verify pinout compatibility and ensure the substitute meets the same thermal and voltage specifications.
