1N4001

Single Diodes Overview

The MDD 1N4001 is an axial lead general purpose silicon rectifier housed in a JEDEC DO-41 molded plastic package. It features a maximum repetitive peak reverse voltage of 50V and a maximum average forward rectified current of 1.0A at 75°C ambient temperature. The device supports a peak forward surge current of 30A under single half-sine-wave conditions. Electrical characteristics include a maximum instantaneous forward voltage of 1.10V at 1.0A, a typical junction capacitance of 15pF, and a thermal resistance of 50°C/W. Operating and storage temperature ranges extend from -55°C to +150°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific part code DO411N4001A105 against the original MDD 1N4001 designation to ensure correct component matching. Confirm that the packaging configuration matches the required AMMO pack or tape/box format containing 5000 pieces per reel. Ensure compliance with RoHS and RoHS III standards is documented for the specific production batch prior to integration into manufacturing processes.

Single Diodes Selection Notes

Select this component when a standard 50V rated silicon rectifier is required for low-frequency applications. The DO-41 axial lead form factor facilitates through-hole mounting on printed circuit boards. Verify that the 1.0A continuous current rating and 30A surge capacity align with the circuit's operational and transient requirements. Consider the 150°C maximum junction temperature limit for thermal management planning in enclosed environments.

Single Diodes Part Context

This component belongs to the DO-41 series of general purpose silicon rectifiers manufactured by MDD. The series includes variants with higher reverse voltage ratings, such as the 1N4002 through 1N4007 types. These devices are designed for general rectification tasks where cost-effectiveness and reliability are prioritized over high-speed switching characteristics. The DO-41 package provides a robust mechanical structure suitable for automated assembly processes.

Single Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N4001 diodes in the DO-41 package, such as those from onsemi or Diodes Inc., provided they meet the same electrical specifications. Cross-reference part numbers like DO411N4001A105 should be validated against the original MDD datasheet to confirm pinout and dimensional compatibility.
