随着技术的发展，电子电路的产品日益多样化，随之而来的是复杂化电子电路很容易在过压、过流、浪涌等情况发生的时候损坏，在各类电子产品中，设置过压保护和过流保护变得越来越重要。电路保护元件也从简单的玻璃管保险丝，变得种类更多，防护性能更优越。那么电路保护如此重要，常用的电路保护元件有哪些？电路保护的意义又是什么？里阳半导体来为大家介绍。

一、常用的电路保护元件有哪些？

1、瞬态抑制二极管

瞬态抑制器TVS二极管广泛应用于半导体及敏感器件的保护，通常用于二级保护。基本都会是用于在陶瓷气体放电管之后的二级保护，也有用户直接将其用于产品的一级保护。其特点为反应速度快（为ps级），体积小，脉冲功率较大，箝位电压低等。其10/1000μs波脉冲功率从400W～30KW，脉冲峰值电流从0.52A～544A；击穿电压有从6.8V～550V的系列值，便于各种不同电压的电路使用。

2、ESD静电放电二极管

ESD静电放电二极管是一种过压、防静电保护元件，是为高速数据传输应用的I/O端口保护设计的器件。ESD静电二极管是用来避免电子设备中的敏感电路受到ESD（静电放电）的影响。可提供非常低的电容，具有优异的传输线脉冲（TLP）测试，以及IEC6100-4-2测试能力，尤其是在多采样数高达1000之后，进而改善对敏感电子元件的保护。

3、自恢复保险丝

自恢复保险丝PPTC就是一种过流电子保护元件，采用高分子有机聚合物在高压、高温、硫化反应的条件下，搀加导电粒子材料后，经过特殊的工艺加工而成。自恢复保险丝（PPTC：高分子自恢复保险丝）是一种正温度系数聚合物热敏电阻，作过流保护用，可代替电流保险丝。电路正常工作时它的阻值很小（压降很小），当电路出现过流使它温度升高时，阻值急剧增大几个数量级，使电路中的电流减小到安全值以下，从而使后面的电路得到保护，过流消失后自动恢复为低阻值。

二、电路保护的意义是什么？

1、由于如今电路板的集成度越来越高，板子的价格也跟着水涨船高，因此我们要加强保护。

2、半导体器件，IC的工作电压有越来越低的趋势，而电路保护的目的则是降低能耗损失，减少发热现象，延长使用寿命。

3、车载设备，由于使用环境的条件比一般电子产品更加恶劣，汽车行驶状况万变，汽车启动时产生很大的瞬间峰值电压等。因此，在为这些电子设备配套产品的电源适配器中，一般要使用过压保护元件。

4、通信设备，通信场所对防雷浪涌有一定的要求，在这些设备中使用过压保护、过流保护元件就变得重要起来，它们是保证用户人身安全和通信正常的关键。

5、大部分电子产品出现的故障，都是电子设备电路中出现的过压或者电路现象造成的，随着我们对电子设备质量的要求越来越高，电子电路保护也变得更加不容忽视。
