1N5825 Schottky Barrier Rectifier Diode 5A 40V

The 1N5825 is a 5A Schottky Barrier Rectifier Diode rated at 40V, offering the low forward voltage drop and fast switching characteristics that set Schottky diodes apart from standard PN-junction rectifiers. Built using chrome barrier metal and epitaxial construction with oxide passivation, it delivers high efficiency and minimal power loss — making it particularly well suited for low-voltage, high-frequency inverters, freewheeling diode applications, and polarity protection circuits.

With a peak non-repetitive surge current of 500A and a maximum junction temperature of 125°C, the 1N5825 handles demanding transient conditions with ease. Its extremely low forward voltage drop (typ. 380mV) significantly reduces conduction losses compared to conventional silicon rectifiers, improving overall circuit efficiency in power supply and motor drive designs. The standard axial through-hole package makes it easy to solder onto perfboards and PCBs, and it is fully RoHS compliant. A practical and reliable choice for Arduino-based power circuits, battery chargers, DC-DC converters, and general electronics projects requiring efficient rectification.
