S6QR

Single Diodes Overview

The GeneSiC Semiconductor S6QR is a silicon standard recovery rectifier housed in a DO-4 stud mount package. It supports repetitive peak reverse voltages of 800 V and 1200 V, with a continuous forward current rating of 6 A. The device features a maximum surge non-repetitive forward current of 167 A and a junction-to-case thermal resistance of 2.50 °C/W. Electrical characteristics include a forward voltage of 1.1 V at 6 A and a reverse leakage current of 10 mA at 25 °C. Operating temperature ranges from -55 °C to +150 °C.

Single Diodes Feature Summary

• Standard polarity configuration where the stud serves as the cathode terminal.
• Reverse polarity variant (R) designates the stud as the anode terminal.
• High surge current capability for handling transient loads.

Single Diodes Applications

• General purpose power supply rectification
• Industrial motor drive circuits
• Battery charging systems

Single Diodes Procurement Notes

Verify the specific voltage rating required, as the datasheet covers both 800 V and 1200 V variants within the S6Q family. Confirm the polarity suffix 'R' if stud-anode configuration is needed, as standard units utilize stud-cathode. Ensure mounting hardware matches the 10-32 UNF thread specification for proper mechanical installation.

Single Diodes Selection Notes

Select this component for applications requiring robust surge handling and high-temperature operation up to 150 °C. The DO-4 package facilitates efficient heat dissipation through direct stud mounting. Consider the reverse polarity option if circuit topology requires the stud connection to be positive relative to the leads.

Single Diodes Part Context

This part belongs to the S6K through S6QR series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. These devices are designed for general-purpose rectification in medium-power applications. The series utilizes a rugged DO-4 stud mount package to ensure reliable performance under demanding electrical and thermal conditions.

Single Diodes Replacement Considerations

Compatible substitutes include other 6 A, 800 V/1200 V standard recovery diodes in DO-4 packages. Verify that replacement parts match the 10-32 UNF stud thread and maintain equivalent thermal resistance and surge current ratings.

Single Diodes FAQ

What is the difference between the standard S6Q and the S6QR?

The S6QR indicates a reverse polarity configuration where the stud acts as the anode, whereas the standard S6Q has the stud configured as the cathode.

What is the maximum operating junction temperature?

The maximum operating junction temperature for the S6QR is +150 °C.
