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. Where are Zener diodes used in real life?
Applied to power adapters, overvoltage protection in electronic devices, LED drive circuits, etc.
-
3. What are the special uses of Zener diodes?
Special uses include precision voltage references, overvoltage protection circuits, etc.
-
4. What happens when a Zener diode fails?
If it is overheated or subjected to excessive current, it may cause permanent damage, which will appear as an open or short circuit state.
