1N4044

Single Diodes Overview

The Powerex 1N4044R is a high-power rectifier diode designed for general-purpose applications. It features a single silicon element with a maximum repetitive peak reverse voltage of 50 V and a maximum output current of 275 A. The device supports a non-repetitive peak forward current of 5000 A and operates within a temperature range of -65 °C to 190 °C. It utilizes a metal post/stud mount package with high-current cable terminals, ensuring robust performance in demanding electrical environments.

Single Diodes Feature Summary

• High current handling capability with 275 A continuous output
• Robust thermal stability operating up to 190 °C
• Durable metal post/stud mount construction

Single Diodes Applications

• General purpose rectification
• High current power conversion systems

Single Diodes Procurement Notes

Verify the specific suffix (e.g., R) against official datasheets to confirm terminal configuration and mounting style. Confirm that the 50 V rating aligns with system requirements. Ensure mechanical compatibility with stud mount hardware. Check for any specific qualification status or environmental certifications required by the application.

Single Diodes Selection Notes

Select this component when high current capacity and elevated temperature operation are critical. The metal package and stud mount design facilitate efficient heat dissipation compared to plastic packages. Verify that the 50 V reverse voltage meets the circuit's peak inverse voltage needs while providing adequate margin.

Single Diodes Part Context

This part belongs to the 1N40xx series of rectifier diodes but represents a significantly higher power variant than standard small-signal versions. While other manufacturers produce similar 1N40xx parts in DO-41 packages, the Powerex version is distinguished by its heavy-duty metal construction and high current ratings suitable for industrial power supplies.

Single Diodes Replacement Considerations

Direct substitutes must match the 275 A current, 50 V rating, and stud mount form factor. Generic 1A rectifiers are not compatible due to massive current differences.
