1N5408G

Overview

The 1N5408G is a standard silicon rectifier diode manufactured by SMC Diode Solutions. It features a maximum DC reverse voltage of 1000 V and an average forward rectified current of 3 A. The device utilizes a DO-201AD axial through-hole package. Key electrical characteristics include a forward voltage of 1.1 V at 3 A, a reverse leakage current of 5 µA at 1000 V, and a junction capacitance of 30 pF at 4 V and 1 MHz. It operates within a junction temperature range of -65°C to 150°C.

Feature Summary

• Standard recovery speed exceeding 500 ns for general-purpose applications
• High surge current capability with non-repetitive peak forward current up to 200 A
• Low reverse leakage current of 5 µA at maximum rated voltage
• Robust thermal performance supporting junction temperatures up to 150°C

Applications

• General purpose rectification in power supply circuits
• Bridge rectifier configurations
• Polarity protection in electronic devices

Procurement Notes

Verify the manufacturer part number 1N5408G against official SMC Diode Solutions documentation to ensure authenticity. Confirm that the component meets RoHS3 compliance standards as specified in the datasheet. Check for REACH regulation status and ensure the package type matches the required DO-201AD axial lead configuration for your specific assembly process.

Selection Notes

Select this component when a high-voltage 1000 V rating is required alongside a 3 A continuous current capacity. The standard recovery time makes it suitable for low-frequency AC-to-DC conversion rather than high-speed switching. Ensure the PCB layout accommodates the DO-201AD axial package dimensions and provides adequate clearance for the 1000 V operating voltage.

Part Context

This component belongs to the 1N540 series of general-purpose rectifiers produced by SMC Diode Solutions. It shares the same physical package and basic electrical structure as other variants in the series but is specifically rated for the highest reverse voltage within that lineup. The 'G' suffix typically denotes specific manufacturing or environmental compliance attributes defined by the manufacturer.
