1N4049R

Single Diodes Overview

The Powerex Inc. 1N4049R is a silicon rectifier diode designed for high-current industrial applications. It features a single element configuration with a maximum average rectified current of 275 A and a repetitive peak reverse voltage of 300 V. The device utilizes a stud mount package (DO-205AB/DO-9) with a metal body, supporting operation temperatures from -65 °C to 190 °C. Key electrical characteristics include a maximum non-repetitive peak forward current of 5000 A and a maximum forward voltage of 1.35 V.

Single Diodes Feature Summary

• High thermal stability with an operating temperature range extending up to 190 °C
• Robust mechanical construction using a metal post/stud mount package for secure chassis installation
• Capable of handling significant surge currents up to 5000 A non-repetitive peak forward current

Single Diodes Applications

• Welders
• Power supplies
• Motor controls
• Battery chargers
• General industrial current rectification

Single Diodes Procurement Notes

Verify the specific datasheet version from Powerex Inc. or authorized distributors to confirm exact pinout orientation and mounting torque specifications. Ensure the procurement channel provides original manufacturer documentation to validate the component's authenticity and technical compliance before integration into high-power systems.

Single Diodes Selection Notes

Select this component when a single-phase rectifier with 275 A continuous current capacity and 300 V blocking voltage is required. The stud mount form factor necessitates compatible heatsinking infrastructure. Evaluate thermal management requirements carefully due to the high power dissipation associated with the specified current ratings in industrial environments.

Single Diodes Part Context

This part belongs to the standard rectifier diode category within Powerex Inc.'s discrete semiconductor portfolio. It serves as a general-purpose high-current solution, distinct from low-voltage or fast-recovery variants. The DO-9 package is a legacy industry standard often replaced by modern equivalents but remains prevalent in existing industrial equipment designs requiring robust mechanical mounting.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-9 stud mount diodes rated for 275 A and 300 V. Verify that substitute parts match the physical mounting dimensions and terminal configurations to ensure compatibility with existing chassis layouts without requiring mechanical redesign.
