1. Where are Zener diodes used in real life?
Applied to power adapters, overvoltage protection in electronic devices, LED drive circuits, etc.
-
2. 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.
-
3. What are the special uses of Zener diodes?
Special uses include precision voltage references, overvoltage protection circuits, etc.
-
4. 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.
