1N3883

Single Diodes Overview

The GeneSiC Semiconductor 1N3883 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 400 V and a continuous forward current of 6 A. The device features a maximum reverse recovery time of 200 ns and a forward voltage of 1.4 V at 6 A. It operates within a junction temperature range of -55 °C to 150 °C, with a thermal resistance from junction to case of 2.5 °C/W.

Single Diodes Feature Summary

• High surge capability for robust transient handling
• Fast recovery characteristics suitable for high-speed switching applications
• Stud mount configuration facilitates direct heatsink attachment

Single Diodes Applications

• Industrial power supply circuits
• Motor drive systems
• Inverter bridge configurations

Single Diodes Procurement Notes

Verify the specific manufacturer source, as production rights for this part number have transitioned between entities including GeneSiC Semiconductor, Microchip Technology, and Navitas Semiconductor. Confirm RoHS compliance status, as documentation indicates variations across different manufacturing origins. Ensure the correct polarity variant is selected based on whether the stud functions as the cathode or anode.

Single Diodes Selection Notes

Select this component when a 400 V blocking voltage and 6 A continuous current rating are required in a stud-mount form factor. The 200 ns reverse recovery time makes it appropriate for general-purpose industrial rectification where moderate switching speeds are sufficient. Evaluate thermal management requirements against the 2.5 °C/W junction-to-case resistance for your specific mounting conditions.

Single Diodes Part Context

The 1N3883 belongs to the 1N3879 through 1N3883R series of silicon fast recovery diodes. This family shares identical electrical ratings and physical dimensions, differing primarily in their maximum repetitive peak reverse voltage ratings which range from 50 V to 400 V. All variants utilize the same DO-4 package and thermal characteristics.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 400 V, 6 A fast recovery diodes in the DO-4 package. Verify that any substitute matches the 200 ns reverse recovery time and 1.4 V forward voltage specifications to ensure circuit compatibility.
