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. What are the disadvantages of Zener diodes?
Disadvantages include relatively high power consumption, sensitivity to temperature, and the need for proper heat dissipation.
-
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.
