-
1. What are Zener diodes used for?
They are mainly used for voltage regulation, protecting circuits from overvoltage damage, and as a voltage reference source.
-
2. 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.
-
3. Is every diode a Zener diode?
No. Although all Zener diodes are a type of diode, not all diodes can be called Zener diodes.
-
4. Where are Zener diodes used in real life?
Applied to power adapters, overvoltage protection in electronic devices, LED drive circuits, etc.
