Original title: zener diode _ zener diode
Zener diode, also known as Zener diode in English, is a semiconductor device with high resistance until the critical everse breakdown voltage. At this critical breakdown point, the everse resistance is reduced to a very small value, and the current increases while the voltage remains constant in this low resistance region. Zener diodes are graded according to breakdown voltage. Because of this characteristic, voltage regulators are mainly used as voltage regulators or voltage reference elements. Zener diodes can be connected in series to be used at higher voltages, and more stable voltages can be obtained through series connection.

Zener diode/Zener diode characteristics
(1) the zener diode works in everse breakdown state (ordinary diode will be damaged when everse breakdown occurs).
(2) When the diode everse voltage of the zener diode reaches a certain value, the everse current suddenly increases, and the zener diode enters the breakdown region, but it is not damaged, but enters the normal working state, which is the biggest difference from ordinary diodes.
(3) After the zener diode enters this working state, even if the everse current changes in a large range, theeverse voltage at both ends of the zener diode can basically remain unchanged, which is the voltage stabilizing characteristic of the zener diode.
(4) Of course, if theeverse current continues to increase to a certain value, the zener diode will be completely broken down and damaged.
