1N3901

Single Diodes Overview

The Microchip Technology 1N3901 is a fast recovery rectifier diode designed for high-voltage applications. It features a maximum repetitive peak reverse voltage (VRRM) ranging from 50 to 400 volts, depending on the specific variant within the series. The device supports a continuous forward current rating of 20 amperes and operates with a junction temperature up to 150°C. Housed in the DO-203AB (DO-5) stud mount package, it provides robust performance for industrial power conversion systems requiring reliable high-current rectification.

Single Diodes Procurement Notes

Verify the specific voltage sub-rating required for your design, as the 1N3901 designation covers a range from 50V to 400V VRRM. Confirm that the DO-203AB stud mount package aligns with your thermal management strategy. Ensure compatibility with the 20A current rating under your expected operating conditions. Request the official datasheet to validate electrical parameters before integration.

Single Diodes Selection Notes

Select this component when high current capacity and fast recovery are necessary in a ruggedized form factor. The stud mount option facilitates direct mounting to heatsinks, simplifying thermal management in high-power environments. Consider the voltage derating requirements based on the specific sub-type selected from the 50V to 400V range.

Single Diodes Part Context

This component belongs to the broader family of fast recovery rectifiers produced by Microchip Technology. It shares functional similarities with other high-current diodes but is distinguished by its specific voltage ratings and DO-203AB packaging. The part is often referenced alongside related models like the 1N3899 and 1N3903 within the same product line.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N3901 equivalents such as those from Microsemi or Digitron. Verify pinout compatibility and thermal resistance values. Ensure the substitute part meets or exceeds the 20A current and 150°C junction temperature specifications.
