1N1124R

Single Diodes Overview

The Microchip Technology 1N1124R is a high-reliability power rectifier qualified per MIL-PRF-19500/260. It features a glass passivated die and glass-to-metal seal construction within a DO-203AA (DO-4) stud-mount package. The device supports a peak repetitive reverse voltage of 200 V, an average forward current of 3.3 A at 150°C case temperature, and a peak surge forward current of 25 A. Electrical characteristics include a maximum forward voltage of 2.2 V at 10 A and a maximum reverse leakage current of 5 µA at 25°C.

Single Diodes Feature Summary

• Glass passivated die with glass-to-metal seal construction for enhanced durability
• Qualified to MIL-PRF-19500/260 standards for high reliability applications
• Stud-mount installation in a DO-203AA (DO-4) package

Single Diodes Applications

• High reliability power rectification circuits
• Military and aerospace electronic systems
• Industrial equipment requiring robust diode performance

Single Diodes Procurement Notes

Verify the specific revision level and manufacturing lot traceability against the latest MIL-PRF-19500/260 requirements before procurement. Confirm that the supplier provides appropriate documentation regarding the glass-to-metal seal integrity and environmental testing results. Ensure storage conditions align with the specified range to maintain component reliability throughout the supply chain process.

Single Diodes Selection Notes

Select this component when a ruggedized rectifier with proven military qualification is required. The 200 V rating suits low-voltage high-current applications where standard commercial parts may lack sufficient thermal or mechanical resilience. Consider the 3.3 A continuous current capability at elevated temperatures as a primary constraint for circuit design.

Single Diodes Part Context

This part belongs to the 1N1124 series of high-reliability power rectifiers manufactured by Microchip Technology. It shares the same physical package and general electrical architecture as the non-R version but adheres to strict military quality standards. The series includes variants with different voltage ratings up to 1000 V.

Single Diodes Replacement Considerations

Direct replacements must meet MIL-PRF-19500/260 specifications. Verify compatibility with existing mounting hardware and thermal management solutions due to the fixed stud-mount form factor.
