1N3293R

Single Diodes Overview

The Vishay General Semiconductor 1N3293R is a general-purpose standard recovery rectifier diode rated for 600 V reverse voltage and 100 A average forward current. It utilizes a DO-205AA (DO-8) chassis mount package with stud mounting capabilities. The device features a maximum forward voltage of 1.5 V at 100 A and a junction temperature range of -40°C to 200°C. Reverse leakage current is specified at 24 mA when tested at 300 V.

Single Diodes Feature Summary

• High thermal stability with a junction temperature rating up to 200°C
• Robust mechanical design suitable for chassis and stud mounting applications
• Standard recovery characteristics optimized for general-purpose power conversion

Single Diodes Applications

• Industrial power supply rectification
• Motor drive inverter circuits
• Welding equipment power stages

Single Diodes Procurement Notes

Verify the specific suffix 'R' against the manufacturer datasheet to confirm it denotes the correct variant, as suffixes can indicate packaging or specific testing criteria. Confirm RoHS compliance status directly from the official documentation, as availability and regulatory status may vary by production batch. Ensure the chassis mount interface matches the intended heatsink design.

Single Diodes Selection Notes

Select this component for high-current applications requiring robust mechanical mounting rather than surface-mount solutions. The 100A rating and 200°C junction capability make it suitable for harsh industrial environments. Compare the forward voltage drop against system efficiency requirements and ensure the cooling solution supports the thermal dissipation needs of a DO-205AA package.

Single Diodes Part Context

This part belongs to the 1N329x series of high-power silicon rectifiers manufactured by Vishay. These components are designed for heavy-duty industrial use, offering high surge current handling and reliable operation under demanding electrical conditions. The series typically includes variants with different reverse voltage ratings while maintaining similar current and package specifications.

Single Diodes Replacement Considerations

The 1N3293 is listed as a similar alternative part number. Verify pinout compatibility and exact electrical parameters before substitution. Other manufacturers producing equivalent 100A 600V stud-mount diodes should be evaluated for thermal resistance and mechanical fit.
