FR12B05

Single Diodes Overview

The GeneSiC Semiconductor FR12B05 is a silicon fast recovery rectifier diode housed in a DO-4 (DO-203AA) stud package. It features a maximum repetitive peak reverse voltage of 100 V and a continuous forward current rating of 12 A at a case temperature of 100 °C or lower. The device exhibits a maximum forward voltage of 0.8 V and a maximum reverse recovery time of 500 ns. It supports an operating and storage temperature range from -55 °C to 150 °C, with a thermal resistance junction-to-case of 2.0 °C/W.

Single Diodes Feature Summary

• High surge capability for handling non-repetitive forward current peaks
• Not ESD sensitive for improved handling safety
• Stud base configuration with standard polarity where the stud serves as the cathode

Single Diodes Applications

• Fast recovery rectification circuits
• High power switching applications requiring high surge tolerance
• Industrial power conversion systems

Single Diodes Procurement Notes

Verify the specific part number against official GeneSiC Semiconductor documentation to confirm electrical ratings and physical dimensions. Ensure the procurement specification matches the required voltage class and package type. Confirm compliance with relevant environmental standards if applicable to the end application.

Single Diodes Selection Notes

Select this component when a 100 V blocking voltage and 12 A continuous current are required in a stud-mount configuration. Consider the 500 ns reverse recovery time for switching frequency limitations. Evaluate the thermal management requirements based on the 2.0 °C/W junction-to-case resistance for proper heat sinking design.

Single Diodes Part Context

This component belongs to the FR12B05 thru FR12JR05 series of silicon fast recovery diodes manufactured by GeneSiC Semiconductor. The series offers various voltage ratings ranging from 100 V to 600 V while maintaining consistent current and package characteristics across the lineup.

Single Diodes Replacement Considerations

Compatible substitutes include other 100 V, 12 A fast recovery diodes in the DO-4 stud package. Verify that replacement parts match the 500 ns reverse recovery time and 0.8 V forward voltage specifications to ensure circuit compatibility.
