1N5831

Overview

The GeneSiC Semiconductor 1N5831 is a silicon Schottky barrier rectifier housed in a DO-4 stud mount package. It provides a continuous forward current of 25 A and supports a repetitive peak reverse voltage up to 40 V. The device features a low forward voltage drop and high surge capability, with a non-repetitive peak forward surge current rating of 800 A. Operating junction temperatures range from -55 °C to +150 °C, ensuring reliability in demanding power conversion environments.

Feature Summary

• Utilizes majority carrier conduction for low power loss and high efficiency
• Incorporates guard ring technology for enhanced transient protection
• Designed with high surge capacity to withstand electrical stress

Applications

• General purpose rectification circuits
• Power supply input stages
• DC-DC converter freewheeling paths

Procurement Notes

Verify the specific manufacturer source when ordering, as multiple vendors produce this standard part number. Confirm the terminal configuration matches the application requirements, noting that standard polarity designates the stud as the cathode while reversed polarity variants exist. Ensure the package type aligns with the thermal management strategy for the intended installation.

Selection Notes

Select this component for applications requiring robust current handling in a compact stud-mount form factor. The silicon construction offers a balance between performance and cost for general-purpose rectification. Consider the thermal resistance characteristics when designing heat dissipation solutions to maintain safe operating temperatures under continuous load conditions.

Part Context

This device belongs to the 1N5829 through 1N5831 series of silicon power Schottky diodes. These components are engineered for high-efficiency rectification in industrial and commercial power electronics. The series shares common packaging and mechanical dimensions, allowing for standardized mounting solutions across different voltage ratings within the same product family.

Replacement Considerations

Direct substitutes include the 1N5829 and 1N5830, which share identical current ratings and package styles but differ in maximum reverse voltage specifications. Verify voltage compatibility before substitution to ensure the replacement device can handle the circuit's peak inverse voltage without breakdown.
