压敏电阻选用的基本知识
V1mA=1.5Vp=2.2VAC，式中，Vp 为电路额定电压的峰值。VAC 为额定交流
电压的有效值。ZnO 压敏电阻的电压值选择是至关重要的，它关系到保护效
果与使用寿命。如一台用电器的额定电源电压为 220V，则压敏电阻电压值
V1mA=1.5Vp=1.5 乘以 1.414 乘以 220V=476V，V1mA=2.2VAC=2.2 乘以
一点。压敏电阻的选用，一般选择标称压敏电压 V1mA 和通流容量两个参
数。

SCOPE This specification describes RC series chip resistors with lead free terminations made by thick film process. APPLICATIONS All general purpose application
CONSTRUCTION The resistor is constructed on top of a high-grade ceramic body. Internal metal electrodes are added on each end to make the contacts to the thick film resistive element. The composition of the resistive element is a noble metal imbedded into a glass and covered by a second glass to prevent environmental influences. The resistor is laser trimmed to the rated resistance value. The resistor is covered with a protective epoxy coat, finally the two external terminations (matte tin on Nibarrier) are added, as shown in Fig.4.

压敏电阻
（2）耐冲击特性，即压敏电阻本身应能承受规定的冲击电流，冲击能量，以及多次冲击相继出现时的平均功 率。
（3）寿命特性有两项，一是连续工作电压寿命，即压敏电阻在规定环境温度和系统电压条件应能可靠地工作 规定的时间（小时数）。二是冲击寿命，即能可靠地承受规定的冲击的次数。
（4）压敏电阻介入系统后，除了起到"安全阀"的保护作用外，还会带入一些附加影响，这就是所谓"二次效 应"，它不应降低系统的正常工作性能。这时要考虑的因素主要有三项，一是压敏电阻本身的电容量（几十到几万 PF），二是在系统电压下的漏电流，三是压敏电阻的非线性电流通过源阻抗的耦合对其他电路的影响。
金属氧化
最常见的压敏电阻是金属氧化物压敏电阻（MOV, Metal Oxide Varistor），它包含由氧化锌颗粒与少量其 他金属氧化物或聚合物间隔构成的陶瓷块，夹于两金属片间。颗粒与邻近氧化物交界处会形成二极管效应，由于 有大量杂乱颗粒，使得它等同于一大堆背向相连的二极管，低电压时只有很小的逆向漏电电流，当遇到高电压时， 二极管因热电子与隧道效应而发生逆向崩溃，流通大电流。因此，压敏电阻的电流-电压特性曲线具有高度的非线 性:低电压时电阻高、高电压时电阻低。

压敏电阻参数详解及设计指南
关于压敏电阻的正确使用一、压敏电阻的原理压敏电阻意思是"在一定电流电压范围内电阻值随电压而变"，或者是说"电阻值对电压敏感"的阻器。
相应的英文名称叫“Voltage Dependent Resistor”简写为“VDR”。
随着加在它上面的电压不断增大，它的电阻值可以从MΩ（兆欧）级变到mΩ（毫欧）级。
当电压较低时，压敏电阻工作于漏电流区，呈现很大的电阻，漏电流很小；当电压升高进入非线性区后，电流在相当大的范围内变化时，电压变化不大，呈现较好的限压特性；电压再升高，压敏电阻进入饱和区，呈现一个很小的线性电阻，由于电流很大，时间一长就会使压敏电阻过热烧毁甚至炸裂。
正常使用时压敏电阻处于漏电流区，受到浪涌冲击时进入非线性区泄放浪涌电流，一般不能进入饱和区压敏电阻器的电阻体材料是半导体，所以它是半导体电阻器的一个品种。
现在大量使用的"氧化锌"（ZnO）压敏电阻器，它的主体材料有二价元素（Zn）和六价元素氧（O）所构成。
所以从材料的角度来看，氧化锌压敏电阻器是一种“Ⅱ-Ⅵ族氧化物半导体”。
二、压敏电阻的作用压敏电阻的最大特点是当加在它上面的电压低于它的阀值"UN"时，流过它的电流极小，相当于一只关死的阀门，当电压超过UN时，流过它的电流激增，相当于阀门打开。
利用这一功能，可以抑制电路中经常出现的异常过电压，保护电路免受过电压的损害。
压敏电阻器是一种具有瞬态电压抑制功能的元件，可以用来代替瞬态抑制二极管、齐纳二极管和电容器的组合。
压敏电阻器可以对IC 及其它设备的电路进行保护，防止因静电放电、浪涌及其它瞬态电流（如雷击等）而造成对它们的损坏。
使用时只需将压敏电阻器并接于被保护的IC 或设备电路上，当电压瞬间高于某一数值时，压敏电阻器阻值迅速下降，导通大电流，从而保护IC 或电器设备；当电压低于压敏电阻器工作电压值时，压敏电阻器阻值极高，近乎开路，因而不会影响器件或电器设备的正常工作。
