1N4051R

Single Diodes Overview

The 1N4051R is a standard recovery silicon power rectifier manufactured by Microchip Technology. It features a glass passivated die and a glass-to-metal seal construction for robust performance. The device is designed for stud mounting in the DO-205AB (DO-9) package. Key electrical specifications include a maximum repetitive peak reverse voltage of 500 V and an average forward rectified current rating of 275 A. This component is engineered to handle high surge currents, making it suitable for demanding industrial power applications requiring reliable high-voltage rectification.

Single Diodes Feature Summary

• High surge current capability for robust operation
• Stud mount design in DO-205AB package

Single Diodes Applications

• Industrial power supply rectification
• High-current DC power conversion systems
• General purpose silicon power rectifier circuits

Single Diodes Procurement Notes

Verify the manufacturer marking on the component body to confirm Microchip Technology origin, as this package style is produced by multiple vendors. Ensure the DO-205AB package dimensions match your thermal management requirements. Confirm that the 500V reverse voltage rating meets your circuit's peak inverse voltage demands before integration.

Single Diodes Selection Notes

Select this component when a 275 A current capacity and 500 V blocking voltage are required in a stud-mount configuration. The glass-to-metal seal offers superior environmental protection compared to plastic encapsulated alternatives. Consider the thermal resistance characteristics of the DO-9 package for heatsink design compatibility in high-power density applications.

Single Diodes Part Context

This part belongs to the general-purpose silicon power rectifier category. It utilizes standard recovery technology rather than fast or ultra-fast recovery variants. The DO-205AB package is a legacy industry-standard form factor often used in heavy-duty industrial equipment where high current handling is critical.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers producing DO-9 500V 275A rectifiers such as Vishay or Powerex. Verify pinout compatibility and thermal interface requirements when substituting with aftermarket equivalents from different suppliers.
