How does a schottky diode?
What is Schottky diode ? A Schottky diode is a special type of diode with a very low forward-voltage drop. When current flows through a diode there is a small voltage drop across the diode terminals. A normal silicon diode has between 0.6–1.7 volt drops[1], while a Schottky diode voltage drop is between approximately 0.15–0.45 volts. This lower voltage drop can provide higher switching speed and better system efficiency. Construction : A Schottky diode uses a metal–semiconductor junction as a Schottky barrier (instead of a semiconductor–semiconductor junction as in conventional diodes). This Schottky barrier results in both very fast switching and low forward voltage drop. Reverse Recory Time : The most important difference between p-n and Schottky diode is reverse recovery time, when the diode switches from non-conducting to conducting state and vice versa. Where in a p-n diode the reverse recovery time can be in the order of hundreds of nanoseconds and less than 100 ns for fast diode
