1N2138AR

Single Diodes Overview

The 1N2138AR is a high-reliability silicon rectifier diode manufactured by Microchip Technology (formerly Microsemi). It features a single-element configuration with a maximum average forward rectified current of 60A and a repetitive peak reverse voltage of 600V. The device utilizes a DO-5 metal package, also known as DO-203AB, designed for stud mounting. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 900A and a maximum forward voltage of 1.3V. The component is classified as a general-purpose rectifier with high surge capability.

Single Diodes Procurement Notes

Verify the manufacturer origin carefully, as this component has been produced by multiple entities including GeneSiC Semiconductor and America Semiconductor under the same part number. Confirm the specific datasheet version and pinout compatibility before integration. Ensure the procurement source provides valid traceability documentation to guarantee the authenticity and quality standards of the silicon die and packaging materials used in production.

Single Diodes Selection Notes

Select this component when a ruggedized, stud-mount rectifier is required for high-current applications. The DO-5 package offers superior heat dissipation compared to standard axial leads. Consider the 600V rating and 60A continuous current limits to ensure adequate margin for the specific circuit load. Verify that the mounting hardware supports the mechanical requirements of the stud terminal configuration.

Single Diodes Part Context

This diode belongs to the legacy Microsemi rectifier portfolio, often associated with MIL-SPEC or industrial-grade specifications. It is functionally equivalent to other 60A/600V DO-5 rectifiers. The part number may appear in databases linked to International Rectifier or GeneSiC due to corporate acquisitions and manufacturing transfers. It represents a standard solution for high-power discrete rectification tasks.

Single Diodes Replacement Considerations

Direct substitutes include the 1N2138APBF from Infineon and generic equivalents from America Semiconductor. Verify that replacement parts maintain the identical DO-5 package dimensions and stud mounting hole patterns. Ensure the alternative supplier's datasheet confirms the 60A current rating and 600V reverse voltage specifications match the original design requirements.
