1N1125A

Single Diodes Overview

The Microchip Technology 1N1125A is a silicon rectifier diode housed in a DO-4 (DO-203AA) threaded stud-mount package. It features a maximum repetitive peak reverse voltage of 300 V and an average forward rectified current rating of 12 A. The device supports a maximum operating temperature of +200°C, ensuring reliability in high-temperature environments.

Single Diodes Feature Summary

• Utilizes a rugged DO-4 threaded stud-mount package for secure mechanical attachment
• Capable of withstanding high junction temperatures up to +200°C
• Designed for standard recovery applications in power conversion circuits

Single Diodes Applications

• Industrial power supply systems
• High-temperature rectification circuits
• General-purpose power control equipment

Single Diodes Procurement Notes

Verify the specific manufacturer source, as components may be produced by Microchip Technology or authorized partners like SSDI. Confirm that the DO-4 package includes the required threaded mounting hardware. Ensure the revision level matches the design requirements before procurement.

Single Diodes Selection Notes

Select this component when a robust stud-mount configuration is necessary for thermal management and mechanical stability. The 12 A current rating and 300 V blocking capability suit moderate-power industrial applications. Consider the +200°C temperature limit for harsh environment deployments where standard packages would fail.

Single Diodes Part Context

This part belongs to the standard silicon rectifier family, characterized by durable metal-glass or epoxy-sealed DO-4 packages. These devices are engineered for industrial durability rather than consumer electronics, prioritizing thermal resistance and mechanical integrity over miniaturization.

Single Diodes Replacement Considerations

Verify pinout compatibility and thermal resistance characteristics against alternatives. Ensure substitute parts maintain the 12 A current rating and 300 V reverse voltage specifications. Confirm that the replacement also utilizes a DO-4 threaded stud mount for direct physical integration.
