RFN3BM2SFHTL

Single Diodes Overview

The RFN3BM2SFHTL is a high-reliability fast recovery diode manufactured by Rohm Semiconductor, designed to meet the AEC-Q101 automotive standard. It features a single configuration housed in a TO-252M (D-Pak) surface-mount package with three terminals. The device supports a maximum repetitive reverse voltage of 200V and an average rectified forward current of 3A. Key electrical characteristics include a maximum forward voltage of 0.98V at 3A and a maximum reverse leakage current of 10µA at 200V. The component exhibits a fast recovery speed with a maximum reverse recovery time of 25ns at 500mA, ensuring efficient switching performance in demanding applications.

Single Diodes Feature Summary

• Complies with AEC-Q101 automotive qualification standards for high reliability
• Features ultra-fast recovery characteristics with minimal reverse recovery time
• Utilizes an epitaxial planar structure for robust switching performance

Single Diodes Applications

• Automotive power supply circuits requiring AEC-Q101 compliance
• High-speed switching applications in DC-DC converters
• General purpose rectification in automotive electronic control units

Single Diodes Procurement Notes

Verify the specific suffix 'TL' indicates tape and reel packaging when sourcing. Confirm the part number matches the exact 3A/200V specification rather than similar variants like RFN5 or RFN6 which differ in current ratings. Ensure the supplier provides documentation confirming AEC-Q101 certification for automotive integration. Cross-reference the manufacturing date code to ensure compatibility with current design requirements.

Single Diodes Selection Notes

Select this component when a 3A current rating and 200V blocking voltage are required in a D-Pak package. It is suitable for designs needing fast recovery times under 25ns. Compare against RFN5BM2SFHTL if higher current capacity is needed, or RF05VYM2SFHTR for lower current SOD-323HE applications. Ensure the thermal management solution supports the TO-252M package constraints for the intended operating temperature range.

Single Diodes Part Context

This part belongs to Rohm's lineup of small signal switching diodes and fast recovery rectifiers. These components utilize an epitaxial planar structure and are available in various high-reliability packages. The RFN series specifically targets applications requiring fast switching speeds and high durability, distinguishing it from standard general-purpose diodes within the broader semiconductor portfolio.

Single Diodes Replacement Considerations

The RFN3BGE2STL is documented as a similar level replacement with the same pinout and package. Verify that the substitute maintains identical electrical parameters, particularly the 25ns reverse recovery time and 3A current rating, before implementation.
