1N5822 Schottky Rectifier Diode

The 1N5822 is a Schottky rectifier diode valued for its low forward voltage drop and fast switching speed compared to standard rectifier diodes. These characteristics make it a popular choice for reverse polarity protection circuits and other applications where switching speed and efficiency matter, though it does trade off a lower reverse breakdown voltage compared to standard diodes.

Rated for a forward current of 3A and a forward surge current of up to 80A, the 1N5822 can handle demanding power applications while keeping conduction losses very low. Its guard ring construction adds overvoltage protection, and the diode is rated for high-frequency operation, making it well suited to DC-DC converters and inverter circuits.
