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. What are the disadvantages of Zener diodes?
Disadvantages include relatively high power consumption, sensitivity to temperature, and the need for proper heat dissipation.
-
3. What are the special uses of Zener diodes?
Special uses include precision voltage references, overvoltage protection circuits, etc.
-
4. What happens when a Zener diode fails?
If it is overheated or subjected to excessive current, it may cause permanent damage, which will appear as an open or short circuit state.
