1N5819 is a surface-mount Schottky Barrier Diode (SBD) with a DO-41 RoHS package, manufactured by Pingwei. This diode has a forward voltage of 0.35 to 0.45 volts, and a reverse voltage of 40 volts, with an average forward current of 1amp. The operating temperature range is between -45C to + 125C. The SBD is designed for general purpose rectification due to its high efficiency, low forward voltage drop, and fast response time. The Schottky Barrier Diode offers low reverse leakage current and high surge capability. 1N5819 is intended for applications requiring high speed switching, low forward voltage drop, and low leakage current. It is suitable for use in clamping circuits, reverse battery protection, and power supplies for portable electronic equipment and appliances.
