1. What are the disadvantages of Zener diodes?
Disadvantages include relatively high power consumption, sensitivity to temperature, and the need for proper heat dissipation.
-
2. Where are Zener diodes used in real life?
Applied to power adapters, overvoltage protection in electronic devices, LED drive circuits, etc.
-
3. What happens if a Zener diode is connected in reverse?
When a Zener diode is properly connected in reverse and a sufficient reverse voltage is applied to exceed its Zener voltage, it will begin to conduct and remain at a relatively constant voltage level.
-
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.
