A Zener diode is a type of diode designed to exploit the Zener effect to affect electric current to flow against the normal direction from anode to cathode, when the voltage across its terminals exceeds a certain characteristic threshold, the Zener voltage.

稳压二极管（zener diode），也称齐纳二极管。 它的特点是利用PN结反向击穿时，其电流可在很大范围内变化而电压基本不变，从而起到稳压作用。 稳压二极管是根据击穿电压来分档的，广泛用于稳压电路和限幅电路中，其电路图符号及常见稳压二极管外形如图1-1 ...

2018年11月6日 · 稳压二极管，英文名称Zener diode，又叫齐纳二极管。 利用pn结反向击穿状态，其电流可在很大范围内变化而电压基本不变的现象，制成的起稳压作用的二极管。

2019年12月11日 · A Zener diode is a silicon pn junction device that allows current to flow not only in the forward direction like a typical silicon or germanium diode, but also in the reverse direction if the voltage is greater than the breakdown voltage known as Zener knee voltage or simply Zener voltage, named after Clarence Melvin Zener, the discoverer of ...

2021年6月30日 · 稳压二极管，又称为齐纳二极管(Zener Diode)，是一种在反向电压下工作时，能够在一定的电压范围内保持稳定输出电压的半导体器件。 它在 电路 设计中主要用于电压稳定、过压保护等场合。

2015年12月16日 · A Zener diode is a silicon semiconductor device that permits current to flow in either a forward or reverse direction. 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.

通过在与普通pn结二极管相反的方向上施加电压，在击穿区域（屈服区域）使用齐纳二极管。 齐纳二极管是一种pn结二极管。 图1显示了pn结二极管的V-I曲线。 典型的pn结二极管使用正向偏压，而齐纳二极管则使用反向偏压，因为其专门用于在击穿区域工作。 根据p型和n型半导体的掺杂浓度，具有以下两种击穿机制。 由于这两种击穿事件都发生在温度恒定的固定电压下，因此齐纳二极管也称为稳压二极管和恒压二极管。 如果p型和n型半导体都具有高掺杂浓度，则围绕结延伸 …

A Zener Diode, also referred to as a breakdown diode, is a specially doped semiconductor device engineered to function in the reverse direction. When the voltage across a Zener diode’s terminals is reversed and reaches the Zener Voltage (also known as the knee voltage), the junction experiences a breakdown, allowing current to flow in the ...

A highly doped semiconductor diode which is designed to operate in reverse direction is known as the Zener diode. In other words, the diode which is specially designed for optimising the breakdown region is known as the Zener diode.
