What are the characteristics of fast recovery diodes?

fast recovery diodes are widely used in circuit applications. So, what are the characteristics of fast recovery diodes?

The reverse recovery time of the fast recovery diode is significantly reduced, approximately below a few hundred nanoseconds; At the same time, the forward voltage drop of the fast recovery diode is lower, and the reverse peak voltage is increased to several thousand volts.

Specific selection method: The advantages of this type of diode are short reverse recovery time, good switching characteristics, and small size. Therefore, it is widely used in circuits such as pulse width modulators, uninterruptible power supplies, switching power supplies, and variable frequency governors. The function of fast recovery diodes is to rectify or continue high frequency and high current.

The internal structure and appearance of fast recovery diodes can be divided into two types: single diode and pair diode. Among them, there are two fast recovery diodes inside the pair diode, and according to the connection method of these two fast recovery diodes, the pair diode can be divided into a common cathode pair diode and a common anode pair diode.
