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 is the difference between a Zener diode and a Schottky diode?
Schottky diodes have a low forward voltage drop and fast switching speed, making them suitable for high-frequency applications. In contrast, Zener diodes are mainly used for voltage regulation and voltage stabilization.
-
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. 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.
