The 1N5408 is a general-purpose silicon rectifier diode rated at 3A continuous forward current and 1000V peak reverse voltage — the highest voltage rating in the 1N540x series. Housed in the robust DO-201AD through-hole package, it is designed for use in mains-referenced power supply circuits, bridge rectifiers, freewheeling diode applications, voltage clamping, and polarity protection in hobbyist and professional electronics projects alike. Its diffused junction construction delivers a low forward voltage drop of 1.0V at rated current, minimising conduction losses, while an impressive 200A peak non-repetitive surge current rating ensures reliable survival of inrush transients during power-up. Low reverse leakage current further improves efficiency in rectification applications. The cathode is identified by a band marking on the body for easy orientation during assembly. RoHS compliant with tin-plated solderable leads per MIL-STD-202, the 1N5408 is a dependable, cost-effective workhorse diode for power electronics builds.
