1N5831

Overview

The 1N5831 is a silicon Schottky barrier rectifier diode manufactured by Microchip Technology. It features a single-element configuration housed in the DO-203AA (DO-4) axial leaded package. The device is rated for a maximum repetitive peak reverse voltage of 40V and supports an average rectified forward current of 25A. It utilizes majority carrier conduction to achieve low power loss and high efficiency, with a guard ring structure provided for transient protection.

Feature Summary

• Schottky barrier technology enabling majority carrier conduction for high efficiency
• Guard ring design incorporated for enhanced transient protection capabilities
• Low forward voltage drop characteristics resulting in reduced power loss

Applications

• General purpose rectification in power supply circuits
• High frequency switching applications requiring fast recovery
• Free-wheeling diodes in inductive load protection

Procurement Notes

Verify component authenticity through official Microchip Technology channels or authorized distributors. Confirm RoHS compliance status as documentation indicates non-compliance. Ensure the DO-4 package variant matches board layout requirements. Validate manufacturing date codes against project timelines to account for potential obsolescence or supply chain delays associated with legacy semiconductor components.

Selection Notes

Select this component when high current handling at low voltage drops is required. The 25A rating suits heavy-duty rectification tasks. Consider thermal management due to bulk package limitations. Compare against modern surface-mount alternatives if space constraints exist. Verify operating temperature range compatibility with environmental conditions.

Part Context

This part belongs to the standard 1N58xx series of Schottky rectifiers. It shares functional similarities with the 1N5829 and 1N5830 but offers higher voltage blocking capability. The DO-4 package provides robust mechanical stability for through-hole mounting. It serves as a legacy solution for industrial equipment maintaining older designs.
