1. What are Zener diodes used for?
They are mainly used for voltage regulation, protecting circuits from overvoltage damage, and as a voltage reference source.
-
2. Are Zener diodes unidirectional?
In normal operation mode, Zener diodes do exhibit unidirectional conductivity, but they start conducting when reverse biased to their Zener voltage.
-
3. 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.
-
4. 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.
