1N3890

Single Diodes Overview

The GeneSiC Semiconductor 1N3890 is a silicon fast recovery rectifier diode housed in a DO-4 (DO-203AA) stud mount package. It supports a repetitive peak reverse voltage of 100 V and a DC blocking voltage of 100 V, with an RMS reverse voltage rating of 70 V. The device handles a continuous forward current of 12 A and withstands a maximum surge non-repetitive forward current of 90 A. Electrical characteristics include a forward voltage of 1.4 V at 12 A and a maximum reverse recovery time of 200 ns. Thermal resistance from junction to case is 2.0 °C/W. Operating and storage temperatures range from -55 °C to 150 °C.

Single Diodes Feature Summary

• High surge capability for handling transient current loads
• Fast recovery performance suitable for high-frequency switching applications
• Robust thermal management via stud mount configuration

Single Diodes Applications

• Power supply circuits requiring fast recovery rectification
• Industrial motor drive systems
• Inverter and converter topologies

Single Diodes Procurement Notes

Verify the specific polarity variant required during procurement. Standard versions feature a cathode stud, while 'R' suffix devices have reversed leads with an anode stud. Confirm compliance with relevant environmental directives such as RoHS and REACH through official manufacturer documentation before finalizing orders.

Single Diodes Selection Notes

Select this component when a 100 V reverse voltage rating and 12 A continuous current capacity are necessary. Ensure the mounting surface can accommodate the stud interface and maintain thermal resistance below 2.0 °C/W. Verify that the application environment stays within the specified -55 °C to 150 °C operating temperature range.

Single Diodes Part Context

This part belongs to the 1N3889 through 1N3893 series of silicon fast recovery diodes. All variants share identical physical dimensions, thermal characteristics, and current ratings, differing only in their maximum reverse voltage capabilities. The 1N3890 specifically targets applications requiring a 100 V blocking voltage threshold.

Single Diodes Replacement Considerations

Compatible substitutes include the 1N3889, 1N3891, and 1N3892, provided the voltage ratings align with circuit requirements. Ensure the replacement maintains the same DO-4 package style and lead configuration to fit existing mechanical layouts.
