how can Fast recovery diode be used in circuits?

Fast recovery diodes are very common in electronic circuit applications, so how can Fast recovery diode be used in circuits?

In the freewheeling circuit, the Fast recovery diode is mainly used to provide a discharge circuit composed of the induced voltage and the Flyback diode for the larger induced voltage, so that the induced voltage is consumed in the circuit in the form of current, thus protecting the components in the circuit from being damaged by the induced voltage. Large induced voltages are generally caused by the loss of power to inductive loads (such as relay coils).

There are many applications of modules and relays! When it is used for Flyback diode, it is often accompanied by absorption reverse peak voltage. At this time, the problem of small reverse withstand voltage of Schottky transistor is exposed, which is inappropriate.
