1N3294AR

Single Diodes Overview

The GeneSiC Semiconductor 1N3294AR is a silicon standard recovery rectifier housed in a DO-8 stud mount package. It features a repetitive peak reverse voltage of 800 V and a continuous forward current rating of 100 A. The device supports a surge non-repetitive forward current of 2300 A under half-sine wave conditions. Electrical characteristics include a maximum forward voltage of 1.5 V at 100 A and a reverse current of 17 mA at rated voltage and 130 °C. Thermal resistance from junction to case is 0.40 °C/W, with an operating temperature range spanning -55 °C to +150 °C.

Single Diodes Feature Summary

• High surge current capability for robust transient handling
• Non-ESD sensitive construction for simplified assembly
• Standard polarity configuration with cathode stud

Single Diodes Applications

• Industrial power supply rectification
• Motor drive circuits
• Inverter bridge configurations

Single Diodes Procurement Notes

Verify the specific suffix designation against official documentation to confirm terminal orientation, as the 'R' variant indicates reversed polarity where the stud functions as the anode rather than the cathode. Confirm RoHS compliance status directly with the manufacturer or authorized distributor records prior to procurement. Ensure thermal interface materials are compatible with the specified junction-to-case thermal resistance for proper heat dissipation.

Single Diodes Selection Notes

Select this component when an 800 V blocking voltage is required alongside a 100 A continuous current capacity in a stud-mount form factor. The DO-8 package facilitates direct mounting to heatsinks. Consider the 0.40 °C/W thermal resistance for thermal management calculations. Verify that the application environment remains within the -55 °C to +150 °C junction temperature limits during operation.

Single Diodes Part Context

This part belongs to the 1N3289A(R) through 1N3294A(R) series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. The series covers reverse voltage ratings from 200 V to 800 V, all sharing identical 100 A forward current ratings and DO-8 packaging. The 1N3294AR represents the highest voltage variant in this specific lineup.

Single Diodes Replacement Considerations

Direct substitutes within the same series include the 1N3293AR (600 V). Cross-manufacturer replacements must match the 800 V VRRM, 100 A IF, DO-8 package dimensions, and 0.40 °C/W thermal resistance specifications.
