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 working principle and characteristics of a transistor are essential knowledge that electronic technicians must master. There are three commonly used working states for a transistor: cutoff, amplification, and saturation, each with different conditions and characteristics. In fact, there is a fourth working state of the transistor in the circuit, although this state is not commonly used, it is also something we must understand.

Field Effect Transistor (FET), abbreviated as FET, is a relatively new type of semiconductor material that uses the electric field effect to control the current of the transistor, hence its name. It is a semiconductor device that uses only one type of carrier to participate in conduction, which is a semiconductor device that controls the output current with input voltage.
