1N3211R

Single Diodes Overview

The GeneSiC Semiconductor 1N3211R is a silicon standard recovery rectifier diode housed in a DO-5 stud mount package. It features a repetitive peak reverse voltage of 300 V and a continuous forward current rating of 15 A. The device supports an operating junction temperature range from -55 °C to +150 °C with a thermal resistance of 0.65 °C/W. The 'R' suffix indicates reverse polarity, where the stud terminal functions as the anode. Maximum surge non-repetitive forward current is rated at 297 A.

Single Diodes Feature Summary

• High surge current capability for robust transient handling
• Reverse polarity configuration with stud as anode
• Not sensitive to electrostatic discharge

Single Diodes Applications

• General purpose rectification in power supplies
• Industrial motor drive circuits
• Battery charging systems

Single Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm polarity orientation. Confirm that the component meets required environmental standards for the intended application. Check availability status as distribution channels may vary. Ensure mounting hardware compatibility with the DO-5 stud configuration prior to procurement.

Single Diodes Selection Notes

Select this component when a 300 V blocking voltage and 15 A continuous current are required in a stud-mount form factor. The reverse polarity variant is suitable for designs requiring the chassis or heatsink to connect to the anode. Evaluate thermal management requirements based on the specified junction-to-case thermal resistance.

Single Diodes Part Context

This part belongs to the 1N3208 through 1N3211R series of silicon standard recovery diodes. The series offers voltage ratings ranging from 50 V to 300 V while maintaining a consistent 15 A current capacity across all variants. All members share identical physical dimensions and thermal characteristics within the DO-5 package.

Single Diodes Replacement Considerations

Direct substitutes include other 1N3211R equivalents from different manufacturers offering identical 300 V/15 A specifications and DO-5 packaging. Verify pinout compatibility, specifically the stud-anode configuration, before substitution.
