1N2258R

Single Diodes Overview

The Microchip Technology 1N2258R is a standard rectifier diode designed for general-purpose applications. It features a DO-4 (DO-203AA) stud-mount package, facilitating robust thermal management and secure mechanical installation in high-power environments. The device is characterized by a repetitive peak reverse voltage of 600V and an average forward current rating of 22A. Key electrical specifications include a maximum DC reverse leakage current of 10µA at rated voltage and a forward voltage drop of 1.2V at full load. These parameters define its operational limits and efficiency characteristics.

Single Diodes Feature Summary

• Utilizes a stud-mount configuration for enhanced thermal dissipation and mechanical stability
• Engineered for general-purpose rectification with high surge current capability
• Constructed using silicon planar technology for reliable long-term operation

Single Diodes Applications

• Industrial power supply rectification circuits
• Battery charging systems requiring high current handling
• DC power conversion equipment

Single Diodes Procurement Notes

Verify the specific datasheet revision to confirm exact electrical tolerances and marking codes. Ensure the mounting surface preparation meets the manufacturer's torque and thermal interface requirements. Confirm that the DO-4 package dimensions align with the intended chassis or heatsink design before finalizing procurement.

Single Diodes Selection Notes

Select this component when a rugged, stud-mounted rectifier is required for currents up to 22A. The 600V reverse voltage rating suits medium-voltage AC-to-DC conversion tasks. Consider the thermal resistance of the DO-4 package and the necessity of an insulating washer if mounting to a grounded heatsink.

Single Diodes Part Context

This part belongs to Microchip's legacy rectifier lineup, often serving as a direct replacement for older military-grade or industrial-standard diodes. The 'R' suffix typically denotes a specific variant within the 1N series, maintaining compatibility with established designs while offering modern manufacturing reliability.

Single Diodes Replacement Considerations

Public sources indicate it replaces the 1N2258R designation from other manufacturers. Verify pinout and thermal pad configurations against existing designs to ensure mechanical compatibility during retrofitting.
