Zener diodes are also called zener diodes. The diode with voltage stabilization is made by using the phenomenon that the current of PN junction can be changed in a large range and the voltage is basically unchanged in the reverse breakdown state.
The regulator is mainly used as a voltage regulator or voltage reference element. Voltage regulator diodes can be connected in series for use at higher voltages, and higher stable voltages can be obtained by series connection.
