1. What are the two types of Zener diodes?
Zener diodes are mainly divided into two types: one that works based on the avalanche effect (usually in high voltage applications) and the other that works based on the Zener breakdown mechanism (suitable for lower voltages).
-
2. 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).
-
3. 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.
-
4. What are the special uses of Zener diodes?
Special uses include precision voltage references, overvoltage protection circuits, etc.
