1N3879R

Single Diodes Overview

The Microchip Technology 1N3879R is a silicon rectifier diode housed in the DO-203AA (DO-4) axial leaded package. It features a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current rating of 6 A. The device exhibits a maximum forward voltage drop of 1.4 V at 20 A and a reverse recovery time of 200 ns. Operating junction temperature ranges from -65°C to 175°C, with a non-repetitive peak forward surge current capacity of 75 A.

Single Diodes Feature Summary

• Designed for fast recovery applications requiring rapid switching capabilities
• Constructed as a single-element silicon rectifier for standard power conversion tasks
• Features terminal installation compatibility via the DO-4 axial leaded housing

Single Diodes Applications

• Fast recovery rectification circuits
• General-purpose power supply rectification
• Free-wheeling diode configurations in inductive loads

Single Diodes Procurement Notes

Verify the specific manufacturer source when ordering, as International Rectifier (Infineon) also produces this part number. Confirm RoHS compliance status, as the Microchip variant is explicitly noted as non-compliant. Ensure the DO-4 package dimensions match your PCB footprint requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component for low-voltage, high-current applications requiring moderate switching speeds. The 50 V rating limits suitability to low-side rectification or clamping roles. Evaluate thermal management needs given the 6 A continuous current rating and the thermal resistance inherent to the DO-4 through-hole package.

Single Diodes Part Context

This component belongs to the standard rectifier diode category within Microchip's discrete semiconductor portfolio. It serves as a legacy replacement for older general-purpose silicon rectifiers. The DO-4 package provides robust mechanical stability for industrial environments compared to smaller surface-mount alternatives.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N3879 equivalents. Verify pinout orientation and physical lead spacing compatibility. Confirm that substitute parts meet the same 50 V reverse voltage and 6 A current specifications.
