1N2131RA

Single Diodes Overview

The Microchip Technology 1N2131RA is a standard recovery rectifier diode housed in a DO-5 (DO-203AB) stud mount package. It features a maximum repetitive peak reverse voltage of 200 V and an average forward current rating of 70 A. The device exhibits a maximum forward voltage drop of 1.3 V at rated current and supports a surge current of up to 900 A. Operating temperatures range from -65°C to +190°C, with a low leakage current of 10 mA.

Single Diodes Feature Summary

• Glass passivated die construction for enhanced reliability
• Stud mount configuration for efficient thermal management
• High surge current capability for robust performance

Single Diodes Applications

• Industrial power supply circuits
• Battery charging systems
• DC power distribution units

Single Diodes Procurement Notes

Verify the specific manufacturer source, as Vishay also produces a VS-1N2131RA variant with a 60 A rating compared to Microchip's 70 A rating. Confirm the exact datasheet version and electrical tolerances match your design requirements before procurement. Ensure mounting hardware compatibility with the DO-5 stud package.

Single Diodes Selection Notes

Select this component when high thermal conductivity via stud mounting is required. Compare the 70 A continuous current rating against load demands. Verify that the 200 V reverse voltage provides sufficient margin for circuit transients. Consider the 1.3 V forward voltage drop for efficiency calculations in high-current applications.

Single Diodes Part Context

This part belongs to the standard silicon junction rectifier category. It utilizes glass passivation to protect the PN junction. The DO-5 package is a legacy but robust form factor designed for high-power dissipation through direct chassis mounting.

Single Diodes Replacement Considerations

Check for equivalent parts from other manufacturers offering identical 200 V / 70 A specifications in a DO-5 package. Note that Vishay's VS-1N2131RA has a lower 60 A rating and may not be a direct substitute for all designs.
