齐纳二极管(稳压二极管)工作原理及主要参数齐纳二极管也叫稳压二极管.一般二极管处于逆向偏压时，若电压超过PIV(逆向峰值电压)值时二极管将受到破坏，这是因为一般二极管在两端的电位差既高之下又要通过大量的电流，此时所产生的功率所衍生的热量足以使二极管烧毁。
齐纳二极管就是专门被设计在崩溃区操作，是一个具有良好的功率散逸装置，可以当做电压参考或定电压组件。
若利用齐纳二极管作为电压调节器，将使附载电压保持在Vz附近且几乎唯一定值，不受附载电流或电源上电压变动影响。
一般二极管之崩溃电压，在制作时可以随意加以控制，所以一般齐纳二极管之崩电压(Vz)从数伏特至上百伏特都有。
一般齐纳二极管在特性表或电路上除了标住Vz外，均会注明Pz也就是齐纳二极管所能承受之做大功率，也可由Pz=Vz*Iz 换算出奇纳二极管可通过最大电流Iz。
dz3w上有个在线计算器,电路设计时可以用来计算稳压二极管的相关参数.齐纳二极管工作原理齐纳二极管主要工作于逆向偏压区，在二极管工作于逆向偏压区时，当电压未达崩溃电压以前，二极管上并不会有电流产生，但当逆向电压达到崩溃电压时，每一微小电压的增加就会产生相当大的电流，此时二极管两端的电压就会保持于一个变化量相当微小的电压值(几乎等于崩溃电压)，下图为齐纳二极管之电压电流曲线，可由此应证上述说明。
齐纳二极管(又叫稳压二极管)它的电路符号是:此二极管是一种直到临界反向击穿电压前都具有很高电阻的半导体器件.在这临界击穿点上,反向电阻降低到一个很少的数值,在这个低阻区中电流增加而电压则保持恒定,稳压二极管是根据击穿电压来分档的,因为这种特性,稳压管主要被作为稳压器或电压基准元件使用.其伏安特性,稳压二极管可以串联起来以便在较高的电压上使用,通过串联就可获得更多的稳定电压。
在通常情况下，反向偏置的PN结中只有一个很小的电流。
这个漏电流一直保持一个常数，直到反向电压超过某个特定的值，超过这个值之后PN结突然开始有大电流导通（图1.15）。

稳压二极管规格啥是稳压二极管呢？稳压二极管就是一种能让电压保持稳定的小玩意儿。
它就像一个电压小卫士，守护着电路中的电压，不让它乱跳。
那稳压二极管的规格都有啥呢？首先得说说它的稳压值。
这就像是给稳压二极管定了一个目标电压。
比如说，有个稳压二极管的稳压值是 5 伏，那它的任务就是让电路中的电压尽量保持在 5 伏左右。
如果电压高了，它就会想办法把电压降下来；如果电压低了，它又会努力把电压升上去。
就像一个超级负责的小管家，时刻盯着电压，不让它出乱子。
然后呢，还有一个重要的规格是最大工作电流。
这就像是给稳压二极管规定了一个能承受的最大工作量。
如果电流超过了这个最大值，稳压二极管可能就会累垮，不能正常工作了。
所以在使用稳压二极管的时候，我们得注意不能让电流太大，不然它可就罢工啦。
还有反向击穿电压也很重要哦。
啥是反向击穿电压呢？简单来说，就是当给稳压二极管加一个反向电压，加到一定程度的时候，它就会被“击穿”，开始导通。
但是这个反向击穿可不是坏事儿哦，它正是稳压二极管能发挥作用的关键。
不过，如果反向电压超过了它的反向击穿电压，那稳压二极管可就真的被弄坏了。
所以我们得知道稳压二极管的反向击穿电压是多少，这样才能安全地使用它。
另外，稳压二极管的功率也是一个需要关注的规格。
功率就像是稳压二极管的“力气”大小。
如果一个稳压二极管的功率大，那它就能承受更大的电流和电压，也能更好地完成稳压的任务。
但是如果功率小，可能就只能用在一些小电流、小电压的场合。
那这些规格对我们有啥用呢？比如说，我们在做电子小制作的时候，如果需要一个稳定的 5 伏电压，那我们就可以找一个稳压值是 5 伏的稳压二极管。
然后再根据我们的电路需要，看看需要多大的工作电流和功率，选择合适的稳压二极管。
如果选错了，可能就会导致电路不能正常工作，或者稳压二极管被烧坏。
而且，不同的稳压二极管规格也会影响它的价格哦。
一般来说，稳压值高、功率大、工作电流大的稳压二极管会比较贵。
