What is a Schottky Diode?

A Schottky Diode is a semiconductor device with unique properties compared to traditional diodes. Named after the physicist Walter Schottky, these diodes are known for their low forward voltage drop and fast switching speed. The Schottky Diode is widely used in electronic circuits where high-speed switching and low power loss are critical. Its structure typically consists of a metal-semiconductor junction rather than a p-n junction, which contributes to its distinctive characteristics.
