1N3881

Single Diodes Overview

The 1N3881 is a silicon fast recovery rectifier diode manufactured by Microchip Technology. It features a single-phase, one-element configuration housed in a DO-203AA (DO-4) metal stud-mount package with one pin. The device supports a maximum average forward output current of 6A and a repetitive peak reverse voltage of 200V. Key electrical parameters include a maximum non-repetitive peak forward surge current of 200A and a maximum forward voltage of 1.4V. The junction temperature range spans from -65°C to 175°C.

Single Diodes Procurement Notes

Verify the specific suffix (e.g., RE3, R) when ordering, as it may indicate packaging or compliance variations. Confirm RoHS status and lead times directly with Microchip Technology or authorized distributors, as production cycles can vary. Ensure the DO-4 stud-mount interface matches your thermal management design requirements before procurement.

Single Diodes Selection Notes

Select this component for applications requiring a 6A continuous current rating with fast recovery characteristics. The 200V reverse voltage rating defines its suitability for low-to-medium voltage DC circuits. Consider the stud-mount package for superior heat sinking compared to standard axial leads. Verify that the 1.4V forward voltage drop aligns with system efficiency targets.

Single Diodes Part Context

This part belongs to the Microchip Technology discrete semiconductor diode portfolio, specifically within the rectifier category. It is part of the legacy 1N388x series, which includes variants with different voltage ratings such as 1N3880 and 1N3883. These components are designed for general-purpose and specialized industrial rectification tasks.

Single Diodes Replacement Considerations

Check datasheets for equivalent parts from other manufacturers offering identical 6A/200V specifications in DO-4 packages. Ensure replacement devices match the fast recovery time and thermal resistance characteristics. Verify pinout compatibility and mounting hole dimensions for direct substitution.
