1N3883

Single Diodes Overview

The Microchip Technology 1N3883 is a standard single rectifier diode housed in the DO-4 (DO-203AA) axial leaded package. It features a maximum DC reverse voltage of 400 V and an average forward rectified current rating of 6 A. The device exhibits a typical forward voltage drop of 1.4 V at 20 A and a reverse leakage current of 15 µA at 400 V. Electrical characteristics include a reverse recovery time of 200 ns, junction capacitance of 115 pF at 10 V and 1 MHz, and a operating junction temperature range from -65°C to +175°C.

Single Diodes Feature Summary

• Designed for general-purpose industrial applications requiring robust power rectification.
• Capable of withstanding high thermal stress with a maximum junction temperature of 175°C.
• Utilizes a screw-terminal mounting style suitable for heavy-duty chassis installations.

Single Diodes Applications

• Industrial power supply rectification
• General purpose AC to DC conversion
• High-voltage DC circuit protection

Single Diodes Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct channels. Confirm that the received units match the specific DO-4 package dimensions and marking codes. Ensure compliance with project requirements regarding non-RoHS status, as this component does not meet RoHS directives. Validate datasheet revisions against the manufacturing change notices provided by the manufacturer prior to final design approval.

Single Diodes Selection Notes

Select the 1N3883 when a 6 A current capacity and 400 V blocking voltage are required in a rugged axial leaded format. Consider the 175°C junction temperature capability for environments exceeding standard commercial limits. Evaluate the 200 ns reverse recovery time to ensure suitability for frequencies below fast-switching thresholds. Compare physical mounting constraints against available PCB or chassis space for the DO-4 terminal configuration.

Single Diodes Part Context

This component belongs to the legacy 1N series of silicon rectifiers manufactured by Microchip Technology. It serves as a high-current alternative to lower-rated variants within the same family. The DO-4 package provides mechanical stability for industrial settings where surface-mount technologies may be insufficient. It represents a standard solution for medium-power rectification tasks in established electronic systems.

Single Diodes Replacement Considerations

Consult official Microchip Technology documentation for verified cross-reference part numbers before substitution. Verify electrical parameters such as peak inverse voltage and forward current ratings match or exceed original specifications. Ensure physical package compatibility and terminal spacing align with existing assembly tooling and board layouts.
