What's the difference between a switching diode and a rectifier diode?

Switching diode:
1. The switching speed of the switching diode is high, that is, the application frequency is high.
2. The switching diode has good high-frequency performance and is mainly used in switching circuits as electronic switches.
Rectifier diode:
1. Rectifier diodes are used in the field of power frequency and high current.
2. The high frequency performance of the rectifier diode is generally not very good (the high frequency performance of the rectifier diode in the switching power supply is also very good), which is mainly used to rectify the power frequency current. It usually works in the state of high voltage and high current.
Of course, in the selection, it also depends on the specific conditions of the circuit, and the specific parameters also need to refer to the specifications.
