1. What are the two types of Zener diodes?
Zener diodes are mainly divided into two types: one that works based on the avalanche effect (usually in high voltage applications) and the other that works based on the Zener breakdown mechanism (suitable for lower voltages).
-
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.
