FR305G

Single Diodes Overview

The FR305G is a fast recovery rectifier diode manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 3 A. The device utilizes a DO-201AD axial through-hole package. Key electrical characteristics include a maximum reverse recovery time of 75 ns and a typical forward voltage drop of 1.3 V at 3 A. The component operates within a junction temperature range of -65°C to 150°C.

Single Diodes Feature Summary

• Fast recovery performance with low reverse recovery time for efficient switching applications
• High current capability with 3 A average forward rectified current rating
• Robust construction in a DO-201AD molded plastic case with UL recognition

Single Diodes Applications

• High frequency switching power supplies
• Free wheeling diodes in inductive load circuits
• Polarity protection circuits

Single Diodes Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official datasheet to confirm compliance with RoHS3 directives and REACH requirements. Ensure the ordering part number matches the exact package style and terminal finish specifications required for the assembly process. Cross-reference the manufacturer product number with authorized distributor listings to confirm current availability status and lead times.

Single Diodes Selection Notes

Select this component when a 400 V blocking voltage and 3 A continuous current are required in a through-hole configuration. The fast recovery characteristic makes it suitable for frequencies exceeding standard rectifier capabilities. Compare the 75 ns reverse recovery time against circuit switching speeds to ensure minimal switching losses. Verify that the DO-201AD footprint aligns with the PCB design constraints.

Single Diodes Part Context

The FR305G belongs to the FR30 series of fast recovery rectifiers from SMC Diode Solutions. This series includes variants with different voltage ratings, such as the FR301G (50 V) through FR307G (1000 V), all sharing the same 3 A current rating and DO-201AD package. The series is designed for general-purpose high-speed rectification in compact form factors.

Single Diodes Replacement Considerations

Compatible substitutes include other 3 A, 400 V fast recovery diodes in the DO-201AD package, such as the MUR340 or HER305. Verify that replacement parts meet the same reverse recovery time and forward voltage specifications to maintain circuit performance.
