1N3889

Single Diodes Overview

The GeneSiC Semiconductor 1N3889 is a silicon fast recovery rectifier diode housed in a DO-4 stud mount package. It supports a repetitive peak reverse voltage of 50 V and a continuous forward current of 12 A. The device features a maximum reverse recovery time of 200 ns and a thermal resistance from junction to case of 2.0 °C/W. Operating temperatures range from -55 °C to +150 °C, with a non-repetitive surge forward current capability of 90 A.

Single Diodes Feature Summary

• High surge current capability for robust transient handling
• Fast recovery characteristics suitable for high-speed switching applications
• Stud mount construction facilitates efficient heat dissipation

Single Diodes Applications

• High frequency power supply circuits
• Inverter and converter topologies
• Free-wheeling rectification in motor drives

Single Diodes Procurement Notes

Verify the specific suffix designation when ordering, as it indicates terminal polarity configuration. Confirm that the supplier provides official datasheets matching the GeneSiC Semiconductor specifications. Ensure the component meets required thermal management standards for the intended operating environment before finalizing procurement.

Single Diodes Selection Notes

Select this component for applications requiring moderate reverse voltage blocking with high current capacity. The DO-4 package allows direct mounting to heatsinks for effective thermal management. Consider the 200 ns recovery time when designing for switching frequencies where faster alternatives might be necessary.

Single Diodes Part Context

This part belongs to the 1N3889 through 1N3893R series of silicon fast recovery diodes. The series shares identical electrical ratings except for the maximum repetitive peak reverse voltage, which varies across the lineup. All variants utilize the same DO-4 stud mount package and thermal characteristics.

Single Diodes Replacement Considerations

Direct substitutes within the same series include the 1N3890, 1N3891, and 1N3892, which offer higher reverse voltage ratings while maintaining identical current and recovery specifications.
