1N4050

Single Diodes Overview

The Microchip Technology 1N4050 is a silicon power rectifier diode designed for high-current applications. It features a glass-to-metal seal construction and a glass-passivated die for enhanced durability. The device offers a reverse voltage rating of 400V and supports a maximum average forward current of 275A at 120°C. It utilizes a DO-9 (DO-205AB) package with stud mounting capabilities, ensuring stable switching characteristics and good thermal behavior under rough service conditions.

Single Diodes Feature Summary

• Glass-to-metal seal construction for robust physical integrity
• Soft recovery characteristics to minimize switching noise
• High surge current capability for demanding power environments
• Stud mount design facilitating efficient heat dissipation

Single Diodes Applications

• AC-to-DC circuit conversion systems
• Rough service industrial power supplies
• General purpose single diode rectification in high-power electronics

Single Diodes Procurement Notes

Verify the manufacturer origin carefully, as multiple entities including International Rectifier and Powerex have historically produced this part number. Confirm the specific suffix or revision if available, as packaging and minor electrical tolerances may vary between original Microchip/Microsemi production and other licensed manufacturers. Ensure the DO-9 package type matches your mechanical constraints.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier with high current handling is required. The 400V rating suits low-voltage AC rectification tasks. Consider the stud mount requirement for installation; it necessitates appropriate heatsinking infrastructure. Compare against higher voltage variants like the 1N4051 if system requirements exceed 400V reverse blocking needs.

Single Diodes Part Context

This device belongs to the general-purpose silicon power rectifier series. It is characterized by its ability to handle significant forward currents while maintaining reliable operation in harsh electrical environments. The DO-9 package is a legacy form factor often used in heavy-duty industrial equipment where space is less constrained than thermal management efficiency.

Single Diodes Replacement Considerations

The 1N4051 serves as a direct substitute with a higher 500V reverse voltage rating but identical current and package specifications. Other equivalents include the 1N4052 (600V). Verify that the replacement maintains the same stud mount configuration and thermal resistance characteristics.
