1N1184

Single Diodes Overview

The Microchip Technology 1N1184 is a standard recovery rectifier diode designed for high-power applications. It features a maximum DC reverse voltage of 50 V and an average forward rectified current rating of 40 A. The device utilizes a DO-203AB (DO-5) stud mount package, supporting junction temperatures up to 200°C. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 50 V and a typical forward voltage drop of 1.19 V at 90 A. This component is classified as a general-purpose rectifier suitable for industrial power conversion systems.

Single Diodes Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm exact electrical tolerances and packaging variations. Confirm compliance requirements such as RoHS status, as military or space-grade variants may differ from commercial equivalents. Ensure the procurement channel provides valid traceability for the DO-203AB package type and stud mount configuration required for your assembly process.

Single Diodes Selection Notes

Select this component when designing circuits that require reliable rectification of currents exceeding 40 A. The 50 V reverse voltage rating limits its use to low-voltage DC applications. Consider the thermal management needs associated with the DO-5 package and the 200°C junction temperature limit. Evaluate the forward voltage drop at expected load currents to ensure efficiency meets system specifications.

Single Diodes Part Context

The 1N1184 belongs to the 1N118x series of high-current rectifiers manufactured by Microchip Technology. This series shares common design principles focused on ruggedness and high thermal stability. These devices are typically used in conjunction with other components in the same family, such as the 1N1186 or 1N1188, which offer different voltage ratings while maintaining similar current handling capabilities.

Single Diodes Replacement Considerations

Cross-reference with equivalent part numbers from other manufacturers offering 40 A, 50 V rectifiers in the DO-203AB package. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement device meets or exceeds the original 200°C junction temperature rating and reverse leakage specifications.
