1. What is the difference between a diode and a Zener diode?
While a normal diode is mainly used for unidirectional current flow, a Zener diode is designed to provide a stable voltage reference point when reverse biased. A normal diode conducts when forward biased and does not conduct or has only a small leakage current when reverse biased; a Zener diode can start conducting after reaching a specific reverse voltage (called the Zener voltage).
-
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. 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. 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.
