1N2138AR

Single Diodes Overview

The GeneSiC Semiconductor 1N2138AR is a silicon standard recovery rectifier diode housed in a DO-5 (DO-203AB) stud mount package. It features a maximum repetitive peak reverse voltage of 600 V and supports a continuous forward current of 60 A. The device exhibits a maximum forward voltage of 1.1 V at 60 A and a thermal resistance from junction to case of 0.65 °C/W. It operates within a temperature range of -55 °C to 150 °C.

Single Diodes Feature Summary

• High surge capability for handling transient currents
• Stud base configuration with cathode connection

Single Diodes Applications

• General purpose rectification
• Power supply circuits
• Industrial equipment

Single Diodes Procurement Notes

Verify the specific part marking against the datasheet to confirm the 600 V rating and standard polarity configuration. Ensure the mounting surface meets the thermal requirements specified for the junction-to-case resistance. Confirm that the stud thread matches the application hardware specifications before finalizing procurement.

Single Diodes Selection Notes

Select this component when a high-voltage, high-current rectifier with robust surge tolerance is required. The DO-5 package facilitates efficient heat dissipation through direct mounting to a heatsink. Consider the 1.1 V forward voltage drop for efficiency calculations in high-current applications.

Single Diodes Part Context

This component belongs to the 1N2133A through 1N2138AR series of silicon standard recovery diodes. All variants share identical physical dimensions, thermal characteristics, and current ratings, differing only in their maximum repetitive peak reverse voltage ratings which range from 300 V to 600 V.

Single Diodes Replacement Considerations

Direct substitutes include other 1N2138A or 1N2138AR variants from different manufacturers that meet the same DO-5 package and 600 V/60 A electrical specifications.
