Schottky rectifiers

Introduction to Schottky Rectifiers

Schottky rectifiers are a vital component in modern electronics, renowned for their efficiency and speed in converting alternating current (AC) to direct current (DC). Named after German physicist Walter H. Schottky, these devices are a type of semiconductor diode that showcases a metal-semiconductor junction, distinguishing them from traditional silicon diodes. Due to their low forward voltage drop and rapid switching capabilities, Schottky rectifiers have become essential in various applications, including power supplies, RF applications, and energy management systems.
