1. 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.
-
2. How to tell if a diode is a Zener diode?
You can tell by looking at its symbol (which is slightly different from ordinary diodes), the description in the data sheet, or by testing its reverse characteristic curve. Using a multimeter, you can also measure its forward and reverse resistance values and the voltage drop under specific conditions.
-
3. Where are Zener diodes used in real life?
Applied to power adapters, overvoltage protection in electronic devices, LED drive circuits, etc.
-
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.
