1. 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.
-
2. How to tell if a diode is a Zener diode?
You can tell by looking at its symbol (which is slightly different from ordinary diodes), the description in the data sheet, or by testing its reverse characteristic curve. Using a multimeter, you can also measure its forward and reverse resistance values and the voltage drop under specific conditions.
-
3. Where are Zener diodes used in real life?
Applied to power adapters, overvoltage protection in electronic devices, LED drive circuits, etc.
-
4. What are the special uses of Zener diodes?
Special uses include precision voltage references, overvoltage protection circuits, etc.
