First, what is a voltage regulator diode

Voltage regulator diode, also known as Zenerdiode, English name: Zenerdiode, is a commonly used diode, the use of pn junction reverse breakdown state, its current can change in a wide range of voltage is basically unchanged phenomenon, made of voltage regulator diode.

Second, the role of voltage regulator diode

The role of the voltage regulator is to maintain the stability of the voltage, in the power supply voltage fluctuations, or other reasons caused by voltage changes at each point in the circuit, the voltage regulator diode can keep the voltage at both ends of the load will be basically unchanged. In series at a higher voltage, the electronic components in the circuit can be protected from being broken down by high current.

Third, the working principle of the voltage regulator diode

The voltage regulator diode is a kind of diode, and also has the basic single pilot characteristics of the diode, that is, the forward pressure is on, and the reverse pressure is not. The general diode reverse pressure exceeds the reverse pressure value of the tube, and the tube is burned. However, the voltage regulator diode is not the same, the voltage regulator diode is reversely pressurized, and when its pn junction is broken down, the voltage at both ends remains basically unchanged.
