1. 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.
-
2. What are the disadvantages of Zener diodes?
Disadvantages include relatively high power consumption, sensitivity to temperature, and the need for proper heat dissipation.
-
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 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.
