1N1202

Single Diodes Overview

The Microchip Technology 1N1202 is a standard recovery rectifier diode designed for high-power applications. It features a maximum repetitive reverse voltage of 200 V and an average forward current rating of 25 A. The device utilizes a stud mount configuration within a DO-203AA (DO-4) package. Key electrical characteristics include a maximum forward voltage of 1.1 V at 30 A, a peak non-repetitive surge current capability of 250 A, and a maximum reverse leakage current of 10 µA at 200 V. It operates across a junction temperature range from -65°C to +200°C.

Single Diodes Feature Summary

• High thermal stability with a maximum junction temperature rating of +200°C
• Robust surge handling capability for transient overload protection
• Stud mount construction for efficient heat dissipation in power modules

Single Diodes Applications

• Industrial power supply rectification
• Motor drive circuits
• Welding equipment power stages

Single Diodes Procurement Notes

Verify the specific suffix code (e.g., BR, C) when ordering, as it may indicate variations in packaging or testing standards. Confirm RoHS compliance status, as some variants in this series are explicitly noted as non-compliant. Ensure the mounting hardware matches the stud configuration specified in the mechanical drawings. Request the latest datasheet revision to confirm any manufacturing changes or PCN updates affecting pinout or materials.

Single Diodes Selection Notes

Select this component for applications requiring high current capacity and wide operating temperature ranges. The 200 V rating suits low-voltage AC-to-DC conversion systems. Consider the DO-4 package size for board space constraints. Evaluate thermal management requirements given the stud mount style. Compare surge current ratings against expected load transients to ensure reliability under fault conditions.

Single Diodes Part Context

The 1N1202 belongs to the 1N1202 series of silicon rectifiers manufactured by Microchip Technology. This series is characterized by high current handling and robust construction suitable for industrial environments. The part is classified as a standard recovery rectifier, distinct from fast-recovery or Schottky types. It shares the basic 1N1202 numbering but may have suffixes denoting specific mechanical or testing attributes.

Single Diodes Replacement Considerations

Cross-reference with other 200V 25A stud-mount rectifiers from manufacturers like Vishay or Littelfuse. Verify that replacement parts match the DO-203AA footprint and terminal dimensions. Ensure equivalent thermal resistance and surge current ratings are maintained in alternative components.
