When a using Zener diode as a voltage regulator, ideally, it has a constant voltage drop equal to its nominal Zener voltage. This constant voltage drop across the Zener diode produced by reverse breakdown is represented by a DC voltage symbol (figure 1) even though the Zener diode does not produce a voltage.
Zener Diode Voltage Regulator Circuit. In a Zener diode voltage regulator circuit, a series resistor (R S) is connected in series with the Zener diode (D Z) to limit current flow. The load resistor (R L) represents the device requiring a stable voltage supply. While the input voltage (V S) may vary, the output voltage (V O) remains constant at ...

Therefore, in breakdown region an ideal zener diode acts as a battery of voltage V Z, and the zener diode is said to be in “ON” State. Case 2.OFF State: When the reverse voltage across the zener diode is less than V Z but greater than 0v, the zener diode is in the “OFF”State. Under such state, the zener diode can be replaced by an Open ...
Both these effects co-occur in a Zener diode but at different voltage levels.
