How to determine the quick recovery of the secondary diode model?

Fast recovery diodes have the characteristics of good performance and short reverse recovery time. Due to their different features, fast recovery diodes play an irreplaceable role in circuit applications. Fast recovery diodes are mainly used in switch mode power supplies,

PWM pulse width modulator, frequency converter and other circuits.

Fast recovery diodes can be distinguished by the naming convention of their models. Surface mount diodes mainly start with RS, FS, and F, while axial diodes mainly start with FR.

Fast recovery of secondary diodes can also be determined by parameters, please refer to the specification sheet for details.
