1N5404K

Overview

The Diotec Semiconductor 1N5404K is a standard recovery rectifier diode housed in the DO-204AC (DO-15) axial through-hole package. It features a maximum repetitive peak reverse voltage of 400 V and supports a maximum average forward rectified current of 3 A at 75°C. The device exhibits a low forward voltage drop of 1.1 V at 3 A and maintains a low reverse leakage current of 5 µA at its rated voltage. Designed for general-purpose applications, it operates within a junction temperature range of -50°C to 175°C and includes a non-repetitive peak forward surge current capability of 200 A.

Feature Summary

• Standard recovery speed suitable for general-purpose rectification
• High thermal stability with extended operating temperature range
• Robust construction with high surge current handling capability

Applications

• General-purpose power supply rectification
• Battery charging circuits
• DC power adapters

Procurement Notes

Verify the specific manufacturer part number against official Diotec Semiconductor documentation to ensure compatibility with design requirements. Confirm that the DO-204AC package dimensions align with PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure storage conditions meet semiconductor handling standards to prevent moisture damage prior to soldering.

Selection Notes

Select this component when a 400 V blocking voltage and 3 A continuous current rating are required in an axial leaded package. Consider the 1.5 µs reverse recovery time for frequency limitations in switching applications. Evaluate thermal management needs based on the 175°C maximum junction temperature rating. Compare alternative manufacturers offering equivalent electrical specifications if supply chain diversification is necessary.

Part Context

This component belongs to the 1N540x series of silicon rectifier diodes, widely used in industrial and consumer electronics. The 'K' suffix typically denotes specific packaging or tape-and-reel configuration variations depending on the manufacturer's coding system. It serves as a direct replacement for legacy 1N5404 devices from other vendors, maintaining pinout and electrical performance compatibility.

Replacement Considerations

Equivalent parts include Vishay 1N5404-E3/54 and LRC 1N5404. Verify package compatibility between DO-204AC and DO-201AD if substituting with different manufacturers.
