It supports a maximum surge current of 80 A and operates within a junction temperature range of -65°C to +175°C. The component has a typical reverse leakage current of 1 µA.

Feature Summary

• Fast recovery performance with 150 ns reverse recovery time
• High thermal stability supporting operation up to 175°C junction temperature
• Robust surge current handling capability of 80 A
• Lead-free construction compliant with RoHS standards

Applications

• General purpose rectification in power supplies
• Free-wheeling diodes in inductive load circuits
• DC-DC converter output rectification

Procurement Notes

Verify the specific suffix (e.g., /TR) when ordering, as it indicates tape-and-reel packaging versus bulk. Confirm the manufacturer's lead time, which may extend significantly due to supply constraints. Ensure the procurement channel provides valid traceability documentation. Cross-reference the datasheet revision date to ensure compatibility with current design requirements. Validate that the component meets all environmental compliance standards required for the final assembly.

Selection Notes

Select this component for applications requiring fast switching speeds and high reliability in axial packages. Compare the 200 V reverse voltage rating against peak circuit voltages to ensure adequate margin. Evaluate the 3 A continuous current limit against thermal dissipation capabilities in the target enclosure. Consider the 150 ns recovery time suitability for the operating frequency. Verify that the through-hole form factor aligns with the printed circuit board layout constraints.

Part Context

This part belongs to the 1N54xx series of fast recovery rectifiers manufactured by Microchip Technology. It shares the same physical footprint and electrical architecture as other variants in the series, differentiated primarily by their reverse voltage ratings. The E3 suffix denotes lead-free termination finish. This series is widely used in industrial and consumer electronics where robust axial-leaded components are preferred over surface-mount alternatives.

Replacement Considerations

Direct substitutes include the 1N5418E3 (400V rating) if higher voltage tolerance is needed, or the 1N5416E3 (100V rating) if lower voltage suffices. Other manufacturers produce equivalent 3A 200V fast recovery diodes in the DO-41/B-package format. Verify pinout compatibility and thermal characteristics before substitution.
