1N5418E3/TR

Overview

The Microchip Technology 1N5418E3/TR is a fast recovery rectifier diode designed for through-hole mounting in the B-Package-2 configuration. It features a single diode configuration with a maximum repetitive reverse voltage of 400 V and an average forward current rating of 3 A. The device exhibits a forward voltage drop of 1.5 V at rated current and supports a maximum surge current of 80 A. Key electrical characteristics include a reverse leakage current of 1 uA and a typical reverse recovery time of 150 ns. The component operates within a temperature range from -65 C to +175 C.

Feature Summary

• Fast recovery performance suitable for high-frequency switching applications
• High thermal stability with extended operating temperature range up to 175 C
• Robust surge current handling capability for transient protection

Applications

• General-purpose rectification in power supply circuits
• Free-wheeling diodes in inductive load switching
• DC-AC conversion stages requiring fast recovery characteristics

Procurement Notes

Verify the specific suffix 'TR' against official Microchip documentation to confirm tape-and-reel packaging status, as standard datasheets may list bulk packaging. Confirm RoHS compliance details directly with the manufacturer or authorized distributor. Ensure the ordering part number matches the exact electrical specifications required for your design to avoid compatibility issues.

Selection Notes

Select this component when a 3 A current rating and 400 V blocking voltage are required in a through-hole package. The fast recovery characteristic makes it suitable for applications where standard rectifiers would cause excessive switching losses. Compare the 150 ns recovery time against circuit requirements to ensure adequate performance for the target frequency.

Part Context

This part belongs to the 1N54xx series of glass-passivated junction rectifiers manufactured by Microchip Technology. The 'E3' suffix indicates lead-free construction compliant with environmental standards. These devices are commonly used in industrial and consumer electronics where reliable rectification and moderate speed are necessary.

Replacement Considerations

Consult official substitution guides for equivalent parts such as the 1N5418 without the E3 suffix if leaded components are acceptable. Verify that any replacement maintains the same B-Package-2 footprint and meets the 400 V / 3 A / 150 ns specification profile.
