Description

1N5819 Schottky Diode

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.( Click for wide range of Diodes).

A diode is a device that allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above.

The 1N5819 is a Schottky Diode with a forward voltage drop of 600mV and a forward current of 1A. Since it has a very low forward voltage drop it can be used in reverse polarity protection circuits, unlike a normal diode that has more than 1V as forwarding voltage drop 1N5819 only has 600mV drop across it when 1A current is flowing through it.

Compared to normal diodes Schottky diode also has relatively faster switching speeds and hence can be used in high-frequency switching circuits. The reverse blocking voltage for 1N5819 is about 28V only which is kind of a downside for all Schottky diodes so make sure this does not affect the performance in your circuit.
