1N5822 is 3A, 40V, Schottky Barrier Rectifier. A Schottky barrier rectifier, often referred to simply as a Schottky diode, is a type of semiconductor diode that is designed to have very fast switching characteristics and a lower forward voltage drop compared to standard silicon PN junction diodes.

1. Low Forward Voltage Drop: One of the primary advantages of Schottky diodes is their significantly lower forward voltage drop (VF) compared to PN junction diodes. This results in less power dissipation and lower voltage loss when the diode is conducting current. The lower VF is particularly advantageous in high-frequency applications and power conversion circuits where efficiency is crucial.

2. Fast Switching Speed: Schottky diodes exhibit very fast switching characteristics due to their metal-semiconductor junction. They have minimal charge storage and recovery times, making them ideal for high-speed rectification and switching applications.


Absolute Maximum Ratings :

1. Maximum Repetitive Reverse Voltage : Vrrm = 40 V

2. Average Rectified Forward Current : If(av) = 3.0 A

3. Non-repetitive Peak Forward Surge Current : Ifsm = 80 A



1. 3.0 ampere operation at TA = 95°C with no thermal runaway.

2. For use in low voltage, high frequency inverters free wheeling, and polarity protection applications.
