Zener diode (also known as Zener diode) is a semiconductor device that has high resistance until the critical reverse breakdown voltage. At this critical breakdown point, the reverse resistance decreases to a very small value, and in this low resistance region, the current increases while the voltage remains constant.

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.
