The 1N5408 is a general-purpose power diode manufactured by Microchip Technology, belonging to the 1N540x series. It functions as an electronic check valve, allowing current to flow in one direction only, from anode to cathode.
This diode has a maximum current carrying capacity of 3A and can withstand peaks up to 200A. It has a typical forward voltage drop of 1V at 1A and a negligible reverse current of 10µA. The 1N5408 is designed for circuits operating at less than 3A and has a slow recovery time.
It is manufactured in a DO-201AD package, which is slightly larger than the DO-41 package but offers increased ampere handling capabilities compared to diodes like the 1N4007 or 1N4148. The mounting type is through-hole, making it suitable for various PCB applications. The diode has a minimum operating temperature of -65°C and a maximum operating temperature of 125°C.
Key features include small size, high current capability, high surge current capability, and a low forward voltage drop. The plastic package meets UL 94V-0 flammability standards. The 1N5408 is an ideal choice when more forward current is needed than smaller package diodes can provide.
