A1N5404G-G

Overview

The Comchip Technology A1N5404G-G is a standard recovery rectifier diode designed for through-hole mounting in the DO-27 (DO-201AD) axial package. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 3 A. The device exhibits a low forward voltage drop of approximately 1 V at full load and a maximum reverse leakage current of 5 µA. It supports a high surge current capability of 200 A and operates within a junction temperature range of -65°C to +125°C, ensuring reliability in general-purpose power applications.

Feature Summary

• Glass passivated junction for enhanced stability and long-term reliability
• High current capability with low forward voltage drop for efficiency
• Molded plastic epoxy case rated UL 94V-0 for flame retardancy
• Lead-free terminals solderable per MIL-STD-208 standards

Applications

• General purpose rectification in AC/DC power supplies
• Battery charging circuits
• Polarity protection in DC input lines
• Freewheeling diodes in inductive load switching

Procurement Notes

Verify the specific manufacturer part number against official Comchip Technology documentation, as the prefix 'A1' may indicate a specific variant or internal coding not universally standardized across all distributors. Confirm RoHS compliance status and packaging type (e.g., Ammo Pack or Reel) directly with the supplier, as these details are critical for automated assembly processes and regulatory adherence. Ensure the component matches the required electrical specifications for your design before procurement.

Selection Notes

Select this component when a 3 A single-phase rectifier with a 400 V reverse voltage rating is required for through-hole PCB assembly. The DO-27 package provides robust mechanical stability for high-current applications. Consider the 200 A surge current rating for circuits with high inrush currents. Verify that the standard recovery speed meets the frequency requirements of the application, as it is not optimized for high-frequency switching.

Part Context

This component belongs to the 1N540x series of silicon rectifiers, a widely used family of general-purpose diodes. The 'G' suffix typically denotes Green/RoHS-compliant versions manufactured by Comchip Technology. These diodes are industry-standard replacements for similar parts from other manufacturers, offering comparable electrical characteristics in a durable plastic axial package suitable for high-volume manufacturing.

Replacement Considerations

Direct substitutes include the 1N5404 from other manufacturers such as Diodes Incorporated, Vishay, or ON Semiconductor, provided they meet the same 3 A / 400 V specifications. Ensure replacement parts maintain the DO-27 package outline and thermal characteristics. Verify that any alternative also offers glass passivation if environmental stability is a design constraint.
