Overview
The Diodes Incorporated 1N5408-A is a silicon rectifier diode designed for general-purpose applications. It features an average forward rectified current of 3 A and a maximum repetitive peak reverse voltage of 1000 V. The device utilizes a DO-201AD axial through-hole package with a molded epoxy body. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 200 A, a typical forward voltage drop of 1.1 V at 3 A, and a low reverse leakage current of 5 µA at 1000 V. The junction temperature range spans from -65°C to 150°C.
Feature Summary
- Standard recovery speed suitable for general-purpose rectification
- High forward surge current capability for transient protection
- Low reverse leakage current for improved efficiency
- Molded plastic package with UL flammability rating
Applications
- General purpose rectification in power supplies
- Inverter circuits
- Converter topologies
Procurement Notes
Verify the specific suffix 'A' against the official Diodes Incorporated datasheet to confirm if it denotes a specific tape-and-reel packaging variant or a distinct electrical parameter deviation compared to the standard 1N5408G. Ensure the ordering part number matches the required mechanical lead form and compliance certifications such as RoHS3.
Selection Notes
Select this component when a 3 A current rating and 1000 V blocking voltage are required in a standard through-hole configuration. It serves as a direct replacement for legacy 1N5408 designs where Diodes Incorporated manufacturing origin is specified. Consider thermal derating requirements for ambient temperatures exceeding 75°C.
Part Context
This component belongs to the 1N5400 series of general-purpose plastic rectifiers. The series covers reverse voltage ratings from 50 V to 1000 V, sharing identical current handling and package dimensions. The 1N5408 variant specifically targets high-voltage DC output applications within this family.
Replacement Considerations
Cross-reference with Vishay 1N5408-E3/73 or onsemi 1N5408G for pin-compatible alternatives. Verify that substitute manufacturers maintain the same DO-201AD footprint and 1000 V / 3 A ratings.
