1N5404G

Overview

The 1N5404G is a standard recovery silicon rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a maximum average forward rectified current of 3A and a maximum repetitive peak reverse voltage of 400V. The device utilizes a glass passivated chip junction to ensure high reliability and low reverse leakage current. It is housed in a DO-201AD (DO-41) axial leaded package designed for through-hole mounting. The component complies with RoHS directives and is halogen-free, making it suitable for environmentally conscious electronic assemblies requiring robust general-purpose rectification.

Feature Summary

• Glass passivated chip junction construction ensures high reliability and low reverse leakage current
• High surge current capability supports transient load conditions
• Low forward voltage drop contributes to reduced power loss and improved efficiency
• Molded plastic case meets UL 94V-0 flammability classification standards

Applications

• General purpose rectification in AC to DC power supply circuits
• Freewheeling diodes in inductive load switching applications
• Polarity protection in DC input circuitry
• Buckling suppression in relay and motor driver circuits

Procurement Notes

Verify the specific manufacturer lot traceability and confirm compliance documentation status prior to procurement. Ensure the ordering suffix matches the required environmental specifications, such as halogen-free or lead-free requirements. Cross-reference the datasheet revision date to confirm the electrical characteristics align with your design constraints. Confirm the packaging format availability if reel or cut tape quantities are required for assembly.

Selection Notes

Select this component when a 3A continuous current rating and 400V blocking voltage are required for through-hole implementations. The standard recovery speed makes it appropriate for line-frequency applications rather than high-speed switching. Consider the thermal derating requirements for ambient temperatures exceeding 75°C. Verify that the DO-201AD footprint matches the PCB layout constraints and that the lead spacing accommodates the mounting holes.

Part Context

This part belongs to the 1N540x series of general-purpose silicon rectifiers. The 'G' suffix typically denotes green compliant manufacturing, indicating halogen-free materials and lead-free terminals in accordance with international environmental directives. The series offers a range of voltage ratings from 50V to 1000V while maintaining a consistent 3A current capacity and mechanical form factor across variants.

Replacement Considerations

Direct substitutes include other manufacturers' 1N5404 equivalents meeting identical JEDEC DO-201AD dimensions and electrical parameters. Verify that replacement parts maintain the same glass passivation technology and surge current ratings to ensure circuit reliability.
