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. Is every diode a Zener diode?
No. Although all Zener diodes are a type of diode, not all diodes can be called Zener diodes.
-
3. What are the disadvantages of Zener diodes?
Disadvantages include relatively high power consumption, sensitivity to temperature, and the need for proper heat dissipation.
-
4. Can Zener diodes be used as rectifiers?
This is generally not recommended because they are not designed to efficiently convert AC to DC. Rectification is usually done by specialized rectifier diodes.
