1N3889R

Single Diodes Overview

The GeneSiC Semiconductor 1N3889R is a silicon fast recovery rectifier diode housed in a DO-4 (DO-203AA) stud mount package. It features a repetitive peak reverse voltage of 50 V and a continuous forward current rating of 12 A. The device exhibits a maximum forward voltage of 1.4 V at 12 A and a maximum reverse recovery time of 200 ns. It supports a surge non-repetitive forward current of 90 A and operates within a junction temperature range of -55 °C to +150 °C. The thermal resistance from junction to case is 2.0 °C/W.

Single Diodes Feature Summary

• High surge capability for handling transient current loads
• Fast recovery characteristics with low reverse recovery time
• Stud mount construction for efficient thermal dissipation

Single Diodes Applications

• High power rectification circuits
• Free wheeling diode applications
• Industrial power supplies

Single Diodes Procurement Notes

Verify the specific suffix 'R' indicates reversed polarity where the stud functions as the anode rather than the standard cathode configuration. Confirm the manufacturer designation, as sourcing data may list Navitas Semiconductor or GeneSiC Semiconductor for this component family. Ensure the DO-4 package dimensions match the required mounting hardware specifications before procurement.

Single Diodes Selection Notes

Select this component when a 50 V blocking voltage and 12 A continuous current are required in a stud-mount form factor. The 200 ns recovery time suits general fast recovery applications. Consider the reversed polarity configuration if the circuit design requires the stud terminal to serve as the anode connection point.

Single Diodes Part Context

This part belongs to the 1N3889 series of silicon fast recovery diodes manufactured by GeneSiC Semiconductor. The series includes variants with different voltage ratings up to 400 V, all sharing similar current and thermal characteristics. The DO-4 package provides a robust mechanical interface for high-power industrial environments.

Single Diodes Replacement Considerations

Cross-reference with Vishay VS-1N3889 for equivalent electrical performance in a DO-4 package. Verify polarity orientation differences between standard and reversed ('R') suffixes when substituting.
