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. Can 2 Zener diodes be connected in series?
Yes, two or more Zener diodes can be used in series to obtain higher stable voltage values. But pay attention to the power rating and heat dissipation of each diode.
-
4. Where are Zener diodes used in real life?
Applied to power adapters, overvoltage protection in electronic devices, LED drive circuits, etc.
