A Schottky diode is a type of semiconductor device that allows current to flow in one direction while blocking it in the opposite direction. It is known for its low forward voltage drop and fast switching speed, making it ideal for applications like power supplies and radio frequency systems. The diode is made from a metal-semiconductor junction, which differentiates it from standard diodes that use a p-n junction. One of the key advantages of Schottky diodes is their efficiency, especially in high-frequency applications. They generate less heat compared to traditional diodes, which helps improve overall system performance. Common uses include rectification in power converters and protection circuits in electronic devices.
