1N5406K

Overview

The 1N5406K is a silicon rectifier diode manufactured by Diotec Semiconductor, designed for general-purpose applications. It features a maximum average forward rectified current of 3 A and a repetitive peak reverse voltage of 600 V. The device utilizes a DO-204AC (DO-15) axial through-hole package with two terminals. Electrical characteristics include a maximum forward voltage of 1.1 V at 3 A and a reverse leakage current of 5 µA at 600 V. The junction temperature range spans from -50°C to 175°C, ensuring reliable operation across diverse environmental conditions.

Feature Summary

• High current capability with a 3 A average forward rectified rating
• Low leakage current for improved efficiency
• Low forward voltage drop to minimize power loss
• Robust construction with UL 94V-0 rated epoxy

Applications

• General-purpose rectification in power supplies
• Bridging circuits in AC-to-DC conversion
• Polarity protection in DC circuits
• Freewheeling diodes in inductive load switching

Procurement Notes

Verify the specific suffix 'K' against the manufacturer's official datasheet to confirm packaging or variant distinctions. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the DO-204AC package dimensions with your PCB footprint design. Confirm availability status directly with authorized distributors as lead times may vary.

Selection Notes

Select this component when a standard recovery rectifier with 3 A capacity and 600 V blocking voltage is required. The DO-15 package suits through-hole mounting for robust mechanical connections. Consider the 175°C junction temperature limit for high-temperature environments. Compare reverse leakage specifications against circuit sensitivity requirements to ensure optimal performance.

Part Context

The 1N5406K belongs to the widely recognized 1N54xx series of silicon rectifier diodes. This series is standardized for general-purpose power rectification tasks. The 'K' suffix typically denotes specific packaging or tape-and-reel configurations in distributor catalogs, though the electrical characteristics remain consistent with the base 1N5406 specification. It serves as a fundamental discrete semiconductor component in electronic design.

Replacement Considerations

Direct replacements include other manufacturers' 1N5406 variants such as those from Diodes Incorporated or Gulf Semiconductor. Verify that substitute parts match the 3 A current rating, 600 V reverse voltage, and DO-204AC package outline. Ensure thermal and electrical parameters align with the original design constraints.
