1N2057R

Single Diodes Overview

The Microchip Technology 1N2057R is a single silicon rectifier diode designed for high-power applications. It features a 200 V repetitive peak reverse voltage and supports an average forward rectified current of 275 A. The device utilizes a stud mount configuration within the DO-205AB (DO-9) package, facilitating efficient thermal management through direct mounting to heatsinks. This component is engineered for robust performance in industrial power conversion systems requiring reliable unidirectional current flow under significant electrical loads.

Single Diodes Feature Summary

• High current handling capability with 275 A average forward rectified current rating
• Robust voltage blocking with 200 V repetitive peak reverse voltage specification
• Durable stud mount construction in DO-205AB package for secure mechanical attachment
• Designed for efficient heat dissipation via direct chassis or heatsink mounting

Single Diodes Applications

• Industrial power supply rectification circuits
• Motor drive inverter bridge configurations
• Welding equipment power stages
• DC-to-AC inversion systems

Single Diodes Procurement Notes

Verify the specific manufacturer source, as this part number has been produced by multiple entities including International Rectifier and Microsemi. Confirm that the received unit matches the required DO-205AB package dimensions and stud thread specifications. Ensure the datasheet corresponds to the actual batch, as historical variations may exist between original IR and subsequent Microchip/Microsemi production runs. Request detailed electrical test reports if operating near maximum ratings.

Single Diodes Selection Notes

Select this component when a standard 200V, 275A rectifier is required in a stud-mount form factor. Consider the thermal resistance characteristics of the DO-205AB package relative to your heatsinking solution. Evaluate the forward voltage drop at rated current to ensure system efficiency meets design targets. Verify compatibility with existing PCB or busbar layouts that accommodate stud-mounted components rather than surface-mount alternatives.

Single Diodes Part Context

The 1N2057R belongs to the family of high-current silicon rectifier diodes originally established by International Rectifier. Following corporate acquisitions, the product line transitioned through Microsemi to Microchip Technology. These devices are standardized under the JEDEC TO-205AB outline, commonly referred to as DO-9, ensuring mechanical interchangeability across manufacturers who produce equivalent specifications for heavy-duty power electronics.

Single Diodes Replacement Considerations

Equivalent parts include the 1N2057AR and 1N2057RA from various manufacturers such as Ruttonsha, Vishay, and Powerex. Verify that substitute components maintain identical voltage and current ratings along with compatible physical mounting dimensions.
