1N3881R

Single Diodes Overview

The GeneSiC Semiconductor 1N3881R 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 200 V and supports a continuous forward current of 6 A. The device exhibits a maximum forward voltage of 1.4 V and a reverse recovery time of 200 ns. 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
• Not ESD sensitive for simplified handling
• Reversed polarity configuration where the stud functions as the anode

Single Diodes Applications

• Fast recovery rectification circuits
• Free wheeling diode applications
• Industrial power conversion systems

Single Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm terminal configuration. Confirm that the reversed polarity variant matches the intended circuit design requirements. Ensure compatibility with existing mounting hardware for the DO-4 package. Validate thermal management solutions align with the specified junction-to-case thermal resistance limits.

Single Diodes Selection Notes

Select this component for applications requiring high-speed switching characteristics combined with moderate current handling capabilities. The stud mount format facilitates efficient heat dissipation through direct chassis mounting. Consider the specific polarity orientation during layout planning to ensure correct electrical connection.

Single Diodes Part Context

This part belongs to the 1N3879 through 1N3883 series of silicon fast recovery diodes. The series offers various voltage ratings while maintaining consistent current and recovery specifications across the lineup. These components are designed for general-purpose high-power rectification tasks.

Single Diodes Replacement Considerations

Compatible substitutes include the 1N3881 without the R suffix, noting the standard polarity difference. Other series members like the 1N3880 or 1N3882 may be used if voltage ratings differ suitably.
