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. 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.
-
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.
