1N3883R

Single Diodes Overview

The GeneSiC Semiconductor 1N3883R is a silicon fast recovery rectifier housed in a DO-4 (DO-203AA) stud mount package. It features a maximum repetitive peak reverse voltage of 400 V and supports a continuous forward current of 6 A. The device exhibits a maximum reverse recovery time of 200 ns and a forward voltage of 1.4 V at 6 A. It withstands a non-repetitive surge current of 90 A and operates within a junction temperature range of -55 °C to 150 °C. The 'R' designation indicates reversed polarity where the stud functions as the anode.

Single Diodes Feature Summary

• High surge capability for robust transient handling
• Fast recovery characteristics with minimal switching losses
• Stud base construction for efficient thermal dissipation

Single Diodes Applications

• Industrial power supply circuits
• Motor drive rectification stages
• Inverter bridge configurations

Single Diodes Procurement Notes

Verify the specific manufacturer source, as production rights may have transferred between entities such as GeneSiC and Microchip Technology. Confirm that the 'R' suffix correctly denotes the reversed polarity configuration required by your circuit design. Ensure compliance with applicable environmental regulations prior to procurement.

Single Diodes Selection Notes

Select this component when a high-voltage fast recovery diode with stud mounting is required. The 400 V rating suits medium-voltage applications, while the 200 ns recovery time balances switching speed and cost. Verify that the thermal resistance allows adequate heat sinking for the expected load conditions.

Single Diodes Part Context

This part belongs to the 1N3879 through 1N3883 series of silicon fast recovery diodes. The series shares identical electrical ratings except for the reverse voltage breakdown level. The 1N3883 variant specifically provides the highest voltage rating within this standard lineup.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' equivalents rated for 400 V, 6 A, and 200 ns recovery in a DO-4 package. Verify pinout compatibility, particularly regarding the stud polarity, before substitution.
