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 are Zener diodes used for?
They are mainly used for voltage regulation, protecting circuits from overvoltage damage, and as a voltage reference source.
-
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.
