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. 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.
-
4. What are the special uses of Zener diodes?
Special uses include precision voltage references, overvoltage protection circuits, etc.
