1N5806URS

Overview

The 1N5806URS is a fast recovery rectifier manufactured by Microchip Technology. It features a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current of 2.5 A. The device utilizes a surface-mount D-5A-2 package. Electrical characteristics include a maximum non-repetitive peak surge current of 35 A, a typical reverse leakage current of 1 µA, and a maximum reverse recovery time of 25 ns. The component operates within a junction temperature range from -65 °C to +175 °C.

Feature Summary

• Fast recovery performance suitable for high-frequency switching applications
• Hermetic surface mount construction in the lightweight LCC-2A compatible footprint
• High thermal conductivity with low case resistance for efficient heat dissipation
• Low leakage current and low forward voltage drop for improved efficiency

Applications

• Secondary ultrafast rectification in switch-mode power converters
• Step-down regulators and DC-to-DC converters
• Chopper drives and free-wheeling diode circuits
• Reverse polarity protection systems

Procurement Notes

Verify the specific suffix 'URS' against official Microchip documentation to confirm exact packaging and qualification status. Ensure compatibility with existing PCB footprints designated for the D-5A-2 or LCC-2A package style. Confirm radiation hardness requirements if deploying in space-qualified environments, as standard commercial variants may differ from military specifications.

Selection Notes

Select this component when a hermetic surface-mount rectifier with fast recovery characteristics is required. The 150 V rating and 2.5 A current capacity define its operational limits. Consider the D-5A-2 package dimensions for board layout constraints. Verify that the operating temperature range meets the environmental demands of the target application.

Part Context

This part belongs to the 1N5806 series of ultrafast rectifiers designed for harsh environments. It shares functional similarities with other hermetic surface-mount diodes but offers specific radiation tolerance and thermal performance metrics. The series is commonly utilized in aerospace and defense electronics where reliability under extreme conditions is critical.

Replacement Considerations

Consult official substitution lists for verified equivalents. Generic replacements may not match the hermetic seal or radiation hardness levels.
