1N1199AR

Single Diodes Overview

The GeneSiC Semiconductor 1N1199AR is a silicon standard recovery rectifier diode housed in a DO-4 (DO-203AA) stud mount package. It features a repetitive peak reverse voltage of 50 V and a continuous forward current rating of 12 A. The device operates within a junction temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum forward voltage of 1.1 V at 12 A, a surge non-repetitive forward current capability of 200 A, and a thermal resistance from junction to case of 2.00 °C/W.

Single Diodes Feature Summary

• High surge current capability for handling transient loads
• Stud base configuration with defined polarity options
• Robust thermal performance with low junction-to-case resistance

Single Diodes Applications

• Industrial power supply rectification
• DC motor drive circuits
• Battery charging systems

Single Diodes Procurement Notes

Verify the specific suffix 'R' indicates reverse polarity where the stud functions as the anode rather than the cathode. Confirm the package type matches the required mechanical mounting interface. Ensure the manufacturer designation aligns with current corporate ownership records due to industry consolidation. Cross-reference datasheet revision dates to validate parameter accuracy before integration into final designs.

Single Diodes Selection Notes

Select this component when a 50 V blocking voltage and 12 A continuous current are required in a stud-mount form factor. The standard recovery characteristic suits lower frequency applications compared to fast recovery alternatives. Evaluate the thermal resistance against the system's heat sink capabilities to ensure junction temperatures remain within the specified operational limits during continuous conduction.

Single Diodes Part Context

This device belongs to the 1N1199A through 1N1206AR series of silicon standard recovery diodes. All variants in this family share identical current ratings and thermal characteristics but differ in their maximum reverse voltage capabilities. The series provides a standardized solution for medium-power rectification tasks requiring robust mechanical mounting via the stud terminal.

Single Diodes Replacement Considerations

Direct substitutes within the same series include the 1N1199A (standard polarity). Other voltage-rated variants such as the 1N1200A or 1N1204A may be considered if higher reverse voltage tolerance is needed, provided the mechanical footprint remains compatible.
