1N2159

Single Diodes Overview

The Microchip Technology 1N2159 is a general-purpose silicon power rectifier diode designed for high-current applications. It features a maximum average forward rectified current of 25A and a repetitive peak reverse voltage of 500V. The device utilizes a DO-5 (DO-203AB) axial leaded package with screw-type mounting terminals, ensuring robust mechanical stability in industrial environments. It operates within a junction temperature range of -65°C to +200°C and exhibits a maximum non-repetitive surge current capability of 400A at 8.3ms. Key electrical characteristics include a maximum DC reverse leakage current of 10µA at rated voltage and a typical forward voltage drop of 1.19V at full load.

Single Diodes Feature Summary

• High thermal stability with an extended operating junction temperature range up to 200°C

• DC motor drive systems

Single Diodes Procurement Notes

Verify the manufacturer origin carefully, as the 1N2159 designation has been produced by multiple entities including Microchip, New Jersey Semi-Conductor, and Central Semiconductor. Confirm the specific datasheet version matches your design requirements regarding tolerance and testing standards. Ensure the package type corresponds to DO-5/DO-203AB specifications. Check for any specific ordering suffixes that may indicate packaging variations or material compliance status before finalizing procurement.

Single Diodes Selection Notes

Select this component when a standard axial rectifier with screw-mounting capability is required for currents up to 25A. Consider the 500V reverse voltage rating against the peak inverse voltage present in the circuit. Evaluate the thermal management needs given the 200°C junction limit. Compare the forward voltage drop against efficiency requirements. Ensure the physical dimensions of the DO-5 package fit the available board space and mounting hardware constraints.

Single Diodes Part Context

The 1N2159 belongs to the family of standard silicon power rectifiers defined by JEDEC TO-220/DO-5 form factors. These components are widely used in legacy and modern industrial equipment requiring reliable AC-to-DC conversion. The part number follows the standard EIAJEDEC numbering system for silicon rectifiers. Microchip Technology continues to support this part alongside other manufacturers who produce equivalent generic designs under the same identifier.

Single Diodes Replacement Considerations

Equivalent parts include the 1N54xx series for lower current applications, though the 1N54xx lacks screw mounting. Direct replacements must match the 25A current rating and 500V reverse voltage. Verify that substitute components support the DO-5 package style if mechanical retention via screws is mandatory. Check if alternative manufacturers offer identical electrical parameters and thermal characteristics.
