FR12D05

Single Diodes Overview

The GeneSiC Semiconductor FR12D05 is a silicon fast recovery rectifier housed in a DO-4 through-hole package. It features a maximum repetitive peak reverse voltage of 600 V and a continuous forward current rating of 12 A at Tj = 25 °C. The device exhibits a typical forward voltage of 1.4 V and a maximum reverse leakage current of 25 µA. Its non-repetitive surge forward current capability reaches 180 A, with a specified recovery time of 500 ns.

Single Diodes Feature Summary

• High surge current capability for robust transient handling
• Fast recovery characteristics suitable for high-frequency switching applications
• Glass passivated chip junction ensuring high reliability

Single Diodes Applications

• High frequency inverters
• Free wheeling diodes
• Polarity protection circuits

Single Diodes Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout configuration, as standard polarity defines the stud as the cathode while reversed polarity variants exist. Confirm RoHS compliance status and packaging quantity directly with authorized distributors or the manufacturer before procurement.

Single Diodes Selection Notes

Select this component when a 600 V blocking voltage and 12 A continuous current are required in a DO-4 axial leaded package. Ensure the application operates within the specified thermal limits and accounts for the 500 ns recovery time in high-speed switching designs.

Single Diodes Part Context

This part belongs to the FR12B05 thru FR12JR05 series of silicon fast recovery diodes manufactured by GeneSiC Semiconductor. The series offers voltage ratings from 100 V to 600 V with a consistent 12 A forward current capacity across different package and speed variants.

Single Diodes Replacement Considerations

Cross-reference with other 600 V, 12 A fast recovery diodes in DO-4 packages from manufacturers such as STMicroelectronics or Vishay. Verify that substitute parts match the forward voltage drop and reverse leakage current specifications to maintain circuit performance.
