1N3291A

Single Diodes Overview

The GeneSiC Semiconductor 1N3291A is a silicon standard recovery rectifier housed in a DO-8 stud mount package. It features a repetitive peak reverse voltage of 400 V and a continuous forward current rating of 100 A. The device supports an operating temperature range from -55 °C to +150 °C with a maximum junction-to-case thermal resistance of 0.40 °C/W. Electrical characteristics include a forward voltage of 1.5 V at 100 A, a reverse current of 24 mA at 130 °C, and a non-repetitive surge current capability of 2300 A.

Single Diodes Procurement Notes

Verify the specific manufacturer source when sourcing this component, as multiple entities including Microchip list similar part numbers. Confirm that the GeneSiC Semiconductor datasheet specifications match your required electrical parameters. Ensure the DO-8 package dimensions align with your mechanical constraints before finalizing procurement orders.

Single Diodes Selection Notes

Select this component for applications requiring high current handling and wide temperature operation. The 400 V reverse voltage rating suits medium-voltage AC-DC conversion tasks. Consider the 0.40 °C/W thermal resistance for heatsink calculations. Verify compatibility with stud mounting hardware due to the specific terminal configuration provided in the documentation.

Single Diodes Part Context

This diode belongs to the 1N3289A through 1N3294A series of silicon standard recovery rectifiers. The series covers reverse voltage ratings from 200 V to 800 V while maintaining a consistent 100 A forward current capacity across all variants. All devices share the same DO-8 package and thermal characteristics, differing primarily in their blocking voltage capabilities.

Single Diodes Replacement Considerations

Devices within the 1N3289A(R) through 1N3294A(R) series are electrically compatible regarding current and thermal ratings. Substitution requires matching the specific reverse voltage requirement. The 'R' suffix indicates reversed polarity where the stud functions as the anode rather than the cathode.
