   A z-dióda (ismert még Zéner-dióda néven is) egy speciális, szilícium alapanyagú dióda, amely feszültségstabilizálásra használatos. Működése nyitóirányban megegyezik a szilícium félvezető diódákéval, azonban záróirányban eltér. Az eltérő viselkedést a p-n átmenet erőteljes szennyezésével [1] érik el.

   A Zener diode is a special type of diode designed to reliably allow current to flow "backwards" (inverted polarity) when a certain set reverse voltage, known as the Zener voltage, is reached. Zener diodes are manufactured with a great variety of Zener voltages and some are even variable.

   How does a Zener diode work?

   • The diode consists of a special, heavily doped p-n junction, designed to conduct in the reverse direction when a certain specified voltage is reached. The Zener diode has a well-defined reverse-breakdown voltage, at which it starts conducting current, and continues operating continuously in the reverse-bias mode without getting damaged.

   Can a Zener diode be overheated?

   • Unless this current is limited by external circuits, the diode may be permanently damaged due to overheating. A Zener diode exhibits almost the same properties, except the device is specially designed so as to have a reduced breakdown voltage, the so-called Zener voltage.

   What is an example of a Zener diode?

   • An example of this kind of use would be a DC error amplifier used in a regulated power supply circuit feedback loop system. Zener diodes are also used in surge protectors to limit transient voltage spikes.

   What does iz mean on a Zener diode?

   • Current Iz (max.): Maximum current at the rated Zener voltage Vz—200 uA to 200 A). Current Iz (min.): Minimum current required for the diode to break down—5 mA and 10 mA. Power rating: The maximum power the Zener diode can dissipate; given by the product of voltage across the diode and the current flowing through.

   A dióda olyan – rendszerint két kivezetéses – elektronikai alkatrész, amelyet többségében egyenirányítás ra, híradástechnikai célra (például rádióvevő készülékekben demodulálásra ), illetve egyszerűbb logikai kapuáramkörökben is alkalmaznak. Nagyáramú, nagyfeszültségű változatai is léteznek.

   In electronics, the Zener effect (employed most notably in the appropriately named Zener diode) is a type of electrical breakdown, discovered by Clarence Melvin Zener. It occurs in a reverse biased p-n diode when the electric field enables tunneling of electrons from the valence to the conduction band of a semiconductor , leading to numerous ...
