1N2129AR

Single Diodes Overview

The GeneSiC Semiconductor 1N2129AR 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 a continuous forward current rating of 60 A. The device supports an operating temperature range from -55 °C to +150 °C with a junction-to-case thermal resistance of 0.65 °C/W. Standard polarity configuration designates the stud as the cathode, while the reverse polarity variant (1N2129AR) designates the stud as the anode.

Single Diodes Feature Summary

• High surge non-repetitive forward current capability
• Not ESD sensitive
• Stud base construction

Single Diodes Applications

• General purpose rectification
• Power supply circuits
• Industrial control systems

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm terminal configuration. The 'A' designation indicates standard polarity where the stud functions as the cathode. The 'R' suffix denotes reverse polarity where the stud serves as the anode. Confirm the required mounting style matches the DO-5 package dimensions before procurement.

Single Diodes Selection Notes

Select this component for applications requiring robust silicon rectification with high thermal stability. The 100 V reverse voltage rating suits low-voltage AC-to-DC conversion tasks. Ensure the cooling solution maintains the case temperature within limits to support the specified 60 A continuous current and 150 °C maximum junction temperature operation.

Single Diodes Part Context

This part belongs to the 1N2128A through 1N2131AR series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. The series offers varying reverse voltage ratings from 50 V to 200 V while maintaining a consistent 60 A forward current capacity across all variants in the lineup.

Single Diodes Replacement Considerations

Direct substitutes include other parts within the 1N2128A through 1N2131AR series that match the 100 V reverse voltage requirement. Verify that any replacement maintains the same DO-5 package footprint and stud polarity configuration.
