They are diodes that are used to keep the voltage applied to their ends constant. Zener diodes do not conduct current up to a certain voltage value. This voltage is called the breakdown or zener voltage (Vz). When connected to the circuit in the correct direction, it works like a normal diode.
When connected in the reverse direction, it does not start conducting until the breakdown voltage (zener voltage), and when the breakdown voltage is exceeded, it passes current in the form of an avalanche effect and starts conducting. When the reverse voltage is removed, the zener diode returns to its normal state. Zener diodes are connected to the circuit in reverse because they work in reverse polarization. The Zener point (breakdown voltage) value is determined by adjusting the amount of additive during the production phase.
