Zener Diode Use
Easyphysics
Zener diode primarily used for?
Select the correct option:
Solution
Incorrect! Answer:
Voltage regulation
- Zener Diode: A heavily doped silicon PN junction diode designed to operate specifically in the reverse breakdown region.
- Characteristic: In the Zener breakdown region, the voltage across the diode remains almost constant (equal to Vz) even for large changes in the reverse current.
- Application: This unique property is utilized for voltage regulation.
- Circuit Role: When placed in parallel with a load, any input voltage fluctuation is 'absorbed' by the Zener's current changes, keeping the load voltage fixed at Vz.
