Schottky diode IN5819 DO-41

The 1N5819 is a Schottky Diode with 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 which has more than 1V as forward 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.

Applications of Diode:

• Can be used to prevent reverse polarity problem
• High Frequency Inverters
• Used as a protection device
• Current flow regulators
• Polarity Protection applications
