zenerfeszültségnek

Zenerfeszültségnek, often referred to as Zener voltage, is a crucial parameter for Zener diodes. It represents the specific reverse voltage at which a Zener diode begins to conduct significant current in the reverse direction. This phenomenon is known as Zener breakdown. When the applied reverse voltage reaches the Zener voltage, the diode exhibits a sharp increase in current, while the voltage across it remains relatively constant.

This characteristic makes Zener diodes highly effective for voltage regulation. By connecting a Zener diode in reverse bias across a varying voltage source, it will maintain a stable output voltage equal to its Zener voltage, provided the input voltage is higher than the Zener voltage and the current through the diode stays within its specified limits. The Zener voltage is a fixed property of a particular Zener diode, determined by its doping concentration during manufacturing. It is typically specified by manufacturers with a certain tolerance. Applications include simple voltage regulators, overvoltage protection circuits, and wave clipping.
