1N5408 Description

Short technical summary and product information.

The 1N5408 is a power diode from the 1N540x series, designed to allow current flow in a single direction. It features a maximum current carrying capacity of 3A and can withstand peak currents up to 200A. The diode has a reverse voltage rating of 1kV and a typical forward voltage drop of 1V at 1A. Its peak reverse current is a negligible 10µA.

 

Manufactured in a DO-201AD package, which is slightly larger than the DO-41 package, the 1N5408 is suitable for applications requiring higher ampere handling capabilities compared to diodes like the 1N4007 or 1N4148. It is designed for through-hole mounting.

 

Key features include a small size with high current capability, high surge current handling, and a low forward voltage drop. The plastic package meets UL 94V-0 flammability standards. This diode is suitable for circuits designed for less than 3A, offering an economical solution for general-purpose rectification needs.
