zener breakdown การใช้

The Zener diode exhibits an apparently similar effect in addition to Zener breakdown.
In the case of Zener breakdown, it starts at a particular voltage.
The lambda diode current approaches zero as voltage increases, before rising quickly again at a voltage high enough to cause gate source Zener breakdown in the FETs.
For example, a diode with a Zener breakdown voltage of 3.2 V exhibits a voltage drop of very nearly 3.2 V across a wide range of reverse currents.
By contrast with the conventional device, a reverse-biased Zener diode exhibits a controlled breakdown and allows the current to keep the voltage across the Zener diode close to the Zener breakdown voltage.
