1N4048

Single Diodes Overview

The Microchip Technology 1N4048 is a standard recovery rectifier diode designed for general-purpose power supply applications. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 1 A. The device utilizes a DO-205AB (DO-9) stud mount package, providing robust mechanical stability for high-power environments. Key electrical characteristics include a maximum RMS voltage of 280 V and a non-repetitive peak forward surge current capability of 30 A at 60 Hz. Operating temperatures range from -65 °C to +175 °C junction temperature.

Single Diodes Procurement Notes

Verify the specific suffix or variant against the official datasheet to ensure compatibility with required voltage and current ratings. Confirm that the mounting hardware matches the stud mount specification. Check for RoHS compliance status if environmental regulations apply to your design. Ensure the supplier provides valid traceability documentation for critical power applications.

Single Diodes Selection Notes

Select this component when a 400 V reverse voltage rating and 1 A continuous current are required in a stud mount configuration. Consider the thermal resistance of the mounting surface to maintain junction temperature within limits. Evaluate the reverse recovery time requirements against the switching frequency of the application circuit.

Single Diodes Part Context

This part belongs to Microchip's legacy rectifier portfolio, often associated with the former International Rectifier or similar acquired lines. It serves as a rugged solution for medium-power AC-to-DC conversion where board space allows for through-hole or chassis mounting. It is distinct from surface-mount alternatives like the SMA or SMB packages.

Single Diodes Replacement Considerations

Direct substitutes must match the 400 V rating, 1 A current, and DO-205AB package. Verify pinout and terminal dimensions for mechanical fit. Cross-reference with other manufacturers' 1N4048 equivalents ensuring identical electrical specifications.
