1N5401-T

Overview

The Lumimax Optoelectronic Technology 1N5401-T is a general-purpose silicon rectifier diode designed for standard recovery applications. It features a DO-201AD (DO-27) axial leaded package with transfer molded plastic construction. The device supports a maximum average forward rectified current of 3.0 A and withstands a maximum repetitive peak reverse voltage of 100 V. Key electrical specifications include a maximum instantaneous forward voltage of 1.1 V, a peak forward surge current capability of 200 A, and a typical junction capacitance of 50 pF. The component operates within a temperature range of -50°C to +150°C.

Feature Summary

• Low forward voltage drop for efficient power conversion
• High forward surge current capability for robust transient handling
• Guaranteed high-temperature soldering resistance up to 250°C
• RoHS and REACH compliant manufacturing standards

Applications

• General purpose rectification in AC/DC power supplies
• Half-wave rectification circuits
• Polarity protection in electronic systems
• Battery charging circuits

Procurement Notes

Verify the specific manufacturer designation when sourcing, as the 1N5401-T suffix indicates a specific packaging or tape-and-reel configuration from Diodes Incorporated in some contexts, whereas Lumimax lists this model under their general 1N540x series. Confirm that the received component matches the DO-201AD physical dimensions and electrical ratings provided in the official Lumimax datasheet. Ensure compliance with RoHS and REACH requirements if applicable to your assembly process. Cross-reference part numbers carefully to avoid confusion between different manufacturers offering identical JEDEC-style designations.

Selection Notes

Select this component for applications requiring a 3A continuous current rating with a 100V reverse voltage blocking capability. The DO-201AD through-hole package is suitable for manual or wave soldering processes. Consider the 1.1V forward voltage drop for efficiency calculations in low-voltage output stages. The wide operating temperature range makes it appropriate for industrial environments. Verify thermal management needs based on the 30°C/W junction-to-ambient thermal resistance specification.

Part Context

The 1N5401 is part of the widely recognized 1N5400–1N5408 series of general-purpose silicon rectifiers. This family shares identical current and surge ratings but varies in reverse voltage breakdown capabilities ranging from 50V to 1000V. The 1N5401 specifically targets 100V applications. Manufactured by Lumimax Optoelectronic Technology, it adheres to standard industry mechanical and electrical forms, fits, and function specifications common to this legacy component type.

Replacement Considerations

Direct replacements include other manufacturers' 1N5401 diodes such as those from Vishay, Diotec, or Central Semiconductor. Ensure substitute parts meet the same 3.0A IF(AV), 100V VRRM, and DO-201AD package constraints. Verify that alternative sources also guarantee high-temperature soldering compatibility.
