FR85M05

Single Diodes Overview

The FR85M05 is a silicon fast recovery rectifier diode manufactured by GeneSiC Semiconductor. It features a maximum DC reverse voltage of 1000 V and an average forward current rating of 85 A. The device utilizes a DO-5 (DO-203AB) package with chassis or stud mount installation. Key electrical characteristics include a maximum reverse recovery time of 500 ns, a forward voltage of 1.4 V at 85 A, and a reverse leakage current of 25 µA at 100 V. The junction operating temperature range extends from -40°C to +150°C.

Single Diodes Feature Summary

• Fast recovery silicon construction optimized for high-speed switching applications
• High thermal stability supporting operation up to 150°C junction temperature
• Robust mechanical design enabling secure chassis or stud mounting

Single Diodes Applications

• High-power industrial motor drives
• Switch-mode power supplies
• DC-DC converter circuits

Single Diodes Procurement Notes

Verify the specific datasheet version to confirm exact pinout dimensions and mounting hole specifications for your chassis design. Ensure the supplier provides traceability documentation consistent with GeneSiC Semiconductor standards. Confirm RoHS compliance status if required by your manufacturing regulations. Cross-reference the part number against official manufacturer lists to avoid counterfeit components.

Single Diodes Selection Notes

Select this component when a single-phase rectifier requires 1000 V blocking capability and 85 A continuous current handling. The 500 ns reverse recovery time makes it suitable for frequencies higher than standard rectifiers but lower than ultra-fast devices. Consider the DO-5 package size for thermal management requirements in your enclosure layout.

Single Diodes Part Context

This part belongs to the GeneSiC Semiconductor FR series of fast recovery rectifiers. It shares the DO-5 package form factor with other high-current variants in the lineup. The series is designed for general-purpose high-power rectification where fast switching performance is critical. It complements lower voltage or lower current options within the same product family.

Single Diodes Replacement Considerations

Check for direct substitutes such as the FR85JR05 for 600 V applications or the FR12M05 for lower current needs. Verify that any replacement maintains the 1000 V reverse voltage rating and compatible mounting interface.
