1N2138RA

Single Diodes Overview

The Microchip Technology 1N2138RA is a standard recovery rectifier diode designed for high-power applications. It features a maximum average forward rectified current of 60 A and a repetitive peak reverse voltage of 600 V. The device utilizes a glass passivated die construction to ensure reliability under harsh conditions. It is housed in a DO-5 (DO-203AB) chassis package, facilitating stud mount installation for efficient thermal management. The component supports a maximum operating temperature of +190°C and includes a surge rating capability.

Single Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N2138RA designation appears across multiple vendors including Vishay and Microchip. Confirm that the received component matches the required electrical specifications, particularly the 60A current rating and 600V blocking voltage. Ensure the package type corresponds to the DO-5 chassis form factor required for your mounting infrastructure before finalizing procurement.

Single Diodes Selection Notes

Select this component when a rugged, stud-mountable silicon rectifier is required for high-current DC conversion. The choice depends on the need for a standard recovery profile rather than ultra-fast switching. Consider the thermal resistance of the chassis mount solution and ensure the system can accommodate the physical dimensions of the DO-5 package while maintaining adequate heat dissipation paths.

Single Diodes Part Context

This component belongs to the family of general-purpose silicon rectifier diodes used in industrial electronics. It serves as a fundamental building block for converting AC to DC in power stages where moderate switching speeds are acceptable. The DO-5 package variant is specifically engineered for applications requiring direct mounting to heatsinks or chassis plates for superior thermal performance compared to leaded packages.

Single Diodes Replacement Considerations

Cross-reference with VS-1N2138RA from Vishay Semiconductors, which shares identical electrical ratings and package style. Verify pinout compatibility and thermal characteristics when substituting between manufacturers to ensure seamless integration without redesigning the mounting hardware.
