1N3297A

Single Diodes Overview

The GeneSiC Semiconductor 1N3297A is a silicon standard recovery rectifier diode housed in a DO-8 (DO-205AA) stud mount package. It features a maximum repetitive peak reverse voltage of 1400 V and a continuous forward current rating of 100 A. The device supports a non-repetitive surge forward current of 2300 A and exhibits a maximum forward voltage of 1.5 V at 100 A. Operating temperatures range from -55 °C to 150 °C, with a thermal resistance junction-to-case of 0.40 °C/W.

Single Diodes Feature Summary

• High surge capability for robust transient handling
• Not ESD sensitive for simplified handling
• Standard polarity configuration with cathode stud

Single Diodes Applications

• General purpose rectification
• Industrial power conversion
• High voltage DC applications

Single Diodes Procurement Notes

Verify the specific suffix designation when ordering, as the datasheet indicates that devices with an 'R' suffix possess reversed polarity where the stud functions as the anode rather than the cathode. Confirm the required voltage rating within the 1000 V to 1400 V family range to ensure compatibility with the system's blocking requirements. Ensure mounting hardware matches the specified thread dimensions for proper mechanical installation.

Single Diodes Selection Notes

Select this component for applications requiring high voltage blocking capabilities up to 1400 V combined with a 100 A continuous current capacity. The DO-8 package facilitates efficient heat dissipation through direct stud mounting to a heatsink. Consider the 0.40 °C/W thermal resistance for thermal management calculations. Verify that the operating environment remains within the specified -55 °C to 150 °C junction temperature limits.

Single Diodes Part Context

This part belongs to the 1N3295A(R) through 1N3297A(R) series of silicon standard recovery diodes. All variants share identical electrical characteristics except for the maximum repetitive peak reverse voltage, which scales across the series. The 1N3297A represents the highest voltage rating variant in this specific lineup, designed for demanding high-voltage rectification tasks.

Single Diodes Replacement Considerations

Direct substitutes include other 1400 V, 100 A stud-mount silicon rectifiers in the DO-8 package. Verify pinout orientation, specifically ensuring the stud connection matches the cathode requirement unless an 'R' variant is used. Thermal resistance and forward voltage specifications should be compared to maintain equivalent performance.
