What are the differences between Schottky diodes and fast recovery diodes

The difference between Schottky diodes and fast recovery diodes can be determined by the following parameters

Reverse withstand voltage: Fast recovery diodes have higher reverse withstand voltage than Schottky diodes.

On state voltage drop: The on state voltage drop of Schottky diodes is smaller than that of fast recovery diodes.

Reverse recovery time: Schottky diodes have a shorter reverse recovery time than fast recovery diodes.

These two types of s are commonly used for switching power supplies. The difference between Schottky diodes and fast recovery diodes is that the recovery time of the former is about 100 times smaller than that of the latter, while the reverse recovery time of the former is about a few nanoseconds! The former has the advantages of low power consumption, high current, and ultra high speed! Of course, the electrical characteristics are all diodes! Fast recovery diodes are manufactured using processes such as gold doping and simple diffusion, which can achieve high switching speed and high voltage resistance. Currently, fast recovery diodes are mainly used as rectifier components in inverter power supplies

Fast recovery diode: with a forward conduction voltage drop of 0.8-1.1V and a reverse recovery time of 35-85nS

Schottky diode: The reverse voltage withstand value is low (generally less than 150V), the on state voltage drop is 0.3-0.6V, and the reverse recovery time is less than 10nS.
