1. What is the difference between a diode and a Zener diode?
While a normal diode is mainly used for unidirectional current flow, a Zener diode is designed to provide a stable voltage reference point when reverse biased. A normal diode conducts when forward biased and does not conduct or has only a small leakage current when reverse biased; a Zener diode can start conducting after reaching a specific reverse voltage (called the Zener voltage).
-
2. Are Zener diodes unidirectional?
In normal operation mode, Zener diodes do exhibit unidirectional conductivity, but they start conducting when reverse biased to their Zener voltage.
-
3. Is every diode a Zener diode?
No. Although all Zener diodes are a type of diode, not all diodes can be called Zener diodes.
-
4. Can Zener diodes be used as rectifiers?
This is generally not recommended because they are not designed to efficiently convert AC to DC. Rectification is usually done by specialized rectifier diodes.
