1N2128AR

Single Diodes Overview

The GeneSiC Semiconductor 1N2128AR is a silicon standard recovery rectifier diode housed in a DO-5 stud mount package. It features a repetitive peak reverse voltage of 50 V and a continuous forward current rating of 60 A. The device supports an operating junction temperature range from -55 °C to +150 °C with a thermal resistance of 0.65 °C/W. It exhibits a maximum forward voltage of 1.1 V at 60 A and can withstand a non-repetitive surge current of 1050 A.

Single Diodes Feature Summary

• High surge current capability for robust transient handling
• Stud base configuration for efficient thermal dissipation
• Not sensitive to electrostatic discharge

Single Diodes Applications

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

Single Diodes Procurement Notes

Verify the specific suffix designation against official documentation, as it determines terminal polarity. Confirm that the stud mounting surface requirements align with the application's thermal management design. Ensure the selected component matches the exact voltage and current ratings required by the circuit specifications before procurement.

Single Diodes Selection Notes

Select this component when a high-current, low-voltage rectifier with stud mounting is required. The 50 V rating suits applications with lower reverse voltage stress. Consider the 0.65 °C/W thermal resistance for heatsink sizing. Verify compatibility with the system's operating temperature range and surge current demands during normal 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 covers voltage ratings from 50 V to 200 V within the same DO-5 package form factor. GeneSiC Semiconductor has been acquired by Navitas Semiconductor, which continues to support these power device platforms.

Single Diodes Replacement Considerations

The datasheet lists the 1N2129AR as a related variant within the same series. Both share identical current and thermal characteristics but differ in reverse voltage ratings. Verify polarity configurations, as the 'R' suffix indicates reversed stud polarity compared to the standard version.
