The 1N5819 is a Schottky diode with a low forward voltage drop and high switching speed. It is commonly used in high-frequency applications like Inverters, DC-DC converters etc. The 1N5819 axial leaded Schottky rectifier has been optimized for very low forward voltage drop, with moderate leakage. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection.
A diode is a device that allows current flow through only one direction. That is the current should always flow from the Anode to the cathode.
Applications of Diode
Can be used to prevent the reverse polarity problem
