1N3893R

Single Diodes Overview

The GeneSiC Semiconductor 1N3893R is a silicon fast recovery rectifier diode housed in a DO-4 (DO-203AA) stud mount package. It features a maximum repetitive peak reverse voltage of 400 V and a continuous forward current rating of 12 A. The device exhibits a maximum reverse recovery time of 200 ns and a forward voltage drop of 1.4 V at 12 A. It supports an operating junction temperature range from -55°C to 150°C with a thermal resistance of 2.0 °C/W.

Single Diodes Feature Summary

• High surge capability for handling transient currents
• Reversed polarity configuration where the stud functions as the anode
• Not sensitive to electrostatic discharge

Single Diodes Applications

• High frequency power conversion circuits
• Free-wheeling applications in inductive loads
• Industrial motor drive systems

Single Diodes Procurement Notes

Verify the specific suffix designation to confirm the reversed polarity configuration, as standard variants differ in terminal orientation. Ensure the mounting surface preparation meets the thermal interface requirements for the specified junction-to-case thermal resistance. Confirm compliance with environmental regulations applicable to your region before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a high-voltage fast recovery rectifier is required in a stud-mount form factor. The 400 V rating suits medium-voltage AC-DC conversion stages. Consider the 12 A current capacity against your circuit's RMS load requirements. Verify that the system can accommodate the physical dimensions of the DO-4 package and the necessary insulation for stud mounting.

Single Diodes Part Context

This part belongs to the 1N3889 through 1N3893R series of silicon fast recovery diodes manufactured by GeneSiC Semiconductor. The series shares identical electrical characteristics regarding current and recovery speed, differentiated primarily by their voltage ratings ranging from 50 V to 400 V. The 'R' suffix specifically denotes the reversed polarity variant within this product line.

Single Diodes Replacement Considerations

Direct replacements must match the 400 V reverse voltage, 12 A current rating, and DO-4 package style. Verify that substitute parts maintain the 200 ns maximum reverse recovery time and compatible thermal resistance specifications to ensure equivalent performance in existing designs.
