1N3289AR

Single Diodes Overview

The GeneSiC Semiconductor 1N3289AR is a silicon standard recovery rectifier housed in a DO-8 package. It supports a repetitive peak reverse voltage of 200 V and a continuous forward current of 100 A. The device features a maximum surge non-repetitive forward current of 2300 A and an I2t rating of 22000 A²sec for fusing protection. Electrical characteristics include a forward voltage of 1.5 V at 100 A and a reverse current of 24 mA at 130 °C. Thermal resistance from junction to case is 0.40 °C/W. Operating and storage temperatures range from -55 °C to +150 °C.

Single Diodes Feature Summary

• High surge capability with robust I2t rating
• Not ESD sensitive
• Stud base configuration

Single Diodes Applications

• Industrial power conversion systems
• General purpose rectification in high current circuits
• Power supply units requiring stud mounting

Single Diodes Procurement Notes

Verify the specific suffix 'R' indicates reversed polarity where the stud functions as the anode rather than the cathode. Confirm the DO-8 package dimensions match the required mechanical footprint. Ensure thermal management solutions accommodate the specified junction-to-case thermal resistance for reliable operation within the rated temperature range.

Single Diodes Selection Notes

Select this component when a 200 V blocking voltage and 100 A continuous current are required in a stud-mountable form factor. Consider the 1N3291AR variant if a higher 400 V reverse voltage rating is necessary while maintaining identical current and thermal specifications. Evaluate the surge current capacity against potential transient loads in the target application circuit.

Single Diodes Part Context

This part belongs to the 1N3289A through 1N3294A series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. All devices in this series share the same DO-8 package, 100 A current rating, and thermal characteristics, differing primarily in their repetitive peak reverse voltage ratings which range from 200 V to 800 V across the lineup.

Single Diodes Replacement Considerations

The 1N3291AR serves as a direct functional substitute within the same series, offering identical current and thermal performance but with a higher 400 V reverse voltage rating instead of 200 V.

Single Diodes FAQ

What is the terminal configuration for the 1N3289AR?

The 'R' suffix denotes reversed polarity, meaning the stud acts as the anode.

What is the maximum operating temperature?

The maximum operating and storage temperature is +150 °C.
