Fast Recovery Diode (FRD) is a semiconductor diode with good switching characteristics and short reverse recovery time. It is mainly used in electronic circuits such as switching power supplies, PWM pulse width modulators, and frequency converters, as a high-frequency rectifier diode, freewheeling diode, or damping diode.

The biggest advantages of Schottky diodes are low impedance, small forward voltage drop, and fast recovery speed, so they are commonly used in high-frequency high current rectification and voltage drop protection circuits.
The main characteristic of a diode is its unidirectional conductivity, which means that under the action of forward voltage, the on resistance is very small; Under the action of reverse voltage, the conduction resistance is extremely high or infinite.
If the diode on the circuit board is damaged, you can still see the original model of the tube and replace it with a diode of the same model.
A bridge stack is an electronic component composed of multiple diodes inside. The main function is rectification, adjusting the direction of current.
