1N2129A

Single Diodes Overview

The GeneSiC Semiconductor 1N2129A is a silicon standard recovery rectifier diode housed in a DO-5 (DO-203AB) stud mount package. It features a repetitive peak reverse voltage of 100 V and supports a continuous forward current of 60 A. The device operates within a junction temperature range of -55 °C to 150 °C, with a thermal resistance from junction to case of 0.65 °C/W. Standard polarity designates the stud as the cathode.

Single Diodes Feature Summary

• High surge capability for handling transient electrical loads
• Non-sensitive to electrostatic discharge events
• Robust stud mount construction for efficient thermal management

Single Diodes Applications

• General purpose power conversion circuits
• Industrial rectification applications
• Medium voltage power processing systems

Single Diodes Procurement Notes

Verify the specific part marking against the datasheet to confirm the 100 V rating and standard polarity configuration. Ensure the mounting surface meets the required thermal interface specifications for the 0.65 °C/W junction-to-case resistance. Confirm that the application environment remains within the specified -55 °C to 150 °C operating temperature limits to maintain device reliability.

Single Diodes Selection Notes

Select this component when a robust stud-mount rectifier is required for high-current applications. The 60 A continuous rating and 100 V blocking voltage suit medium-voltage designs. Consider the DO-5 package dimensions for mechanical integration and verify that the heat sink design can effectively manage the thermal resistance to prevent junction overheating during operation.

Single Diodes Part Context

This component belongs to the 1N2128A through 1N2131AR series of silicon standard recovery diodes. All variants share identical physical packages and thermal characteristics, differing primarily in their voltage ratings which range from 50 V to 200 V. This series provides standardized solutions for general-purpose rectification tasks requiring reliable performance under varying thermal conditions.

Single Diodes Replacement Considerations

Direct substitutes include other 1N2129A units from different manufacturers or compatible parts within the same 1N2128A-1N2131AR family that match the 100 V rating and 60 A current capacity. Verify pinout compatibility, specifically that the stud functions as the cathode, before implementation.
