1N3909A

Single Diodes Overview

The Microchip Technology 1N3909A is a high-reliability fast recovery rectifier diode designed for demanding applications. It features a maximum DC reverse voltage (Vr) of 50 V and an average forward rectified current (Io) rating of 50 A. The device utilizes a DO-203AB (DO-5) axial leaded package suitable for stud or chassis mounting. Key electrical characteristics include a maximum reverse leakage current of 15 µA at 50 V, a forward voltage drop of 1.4 V at 50 A, and a reverse recovery time (trr) of 150 ns. The component operates within a junction temperature range of -65°C to 150°C.

Single Diodes Feature Summary

Fast recovery performance with a specified reverse recovery time of 150 ns for efficient switching operations.
High current handling capability rated at 50 A average forward rectified current.
Qualified per MIL-PRF-19500/308 standards for high reliability in critical environments.
Robust thermal management supporting a maximum junction temperature of 150°C.

Single Diodes Applications

High-power industrial rectification circuits
Military and aerospace power supply systems
Heavy-duty motor drive inverters

Single Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variations such as 'R' or 'AR' may indicate different packaging or qualification levels than the base part number. Confirm RoHS compliance status, as this specific variant is noted as non-compliant in available distributor data. Ensure the procurement channel provides traceability documentation required for military-grade components qualified under MIL-PRF-19500/308.

Single Diodes Selection Notes

Select the 1N3909A when a standard silicon rectifier with fast recovery characteristics is required for high-current applications. The 50 A current rating and 50 V breakdown voltage define its operational limits. Consider the DO-203AB package size for mechanical integration. Compare against the broader 1N3909 series variants if specific packaging or additional qualification certifications are necessary for the target system.

Single Diodes Part Context

The 1N3909A belongs to the 1N3909 family of high-reliability fast recovery rectifiers manufactured by Microchip Technology. This series includes multiple voltage ratings ranging from 50 V to 400 V across devices like the 1N3910 through 1N3913. These components are distinguished by their rugged construction and suitability for harsh environments, often serving as replacements for legacy military-specification diodes in modern designs.
