雷击浪涌防护在电路保护领域内是绝对的主角，尤其在电源设备、安防设备、通信基站、通信铁塔、通讯设备、交通设备等防护方案中，电子工程师必须优先考虑雷击浪涌防护。室外环境的复杂性，在雷雨天气增多的情况下，尤其要注意雷击浪涌的防护。

雷电及浪涌电压电流的幅值都是极高的，而且具有与极高内阻的电流源相近的电流特性，因此在进行雷击浪涌防护方案设计时，工程师可以多往这些方面靠。雷电及浪涌防护的基本原则是使雷电及浪涌所包含的能量按照预先设定好的方式和途径顺利的泄放。

在将来，由于种种原因，浪涌防护产品将变得越来越普及。即：集成密度的提高必然伴随着电路中元器件(集成电路、三极管、二极管、电阻等)临界载荷值的降低；由于使用先进的生产机械，有必要增加生产过程的安全性；电子设备的应用中，要注意露天设备(如带有智能传感器的设备)的保护；核爆炸产生的电磁脉冲危害(NEMP)：这只是核爆炸产生的不可避免的次要结果，它能损坏所有电子设备。

常见的防护方法是电路的关键部位采用过电压和浪涌的防护器件，使过电压和浪涌通过防护器件旁路到大地，从而让电路的瞬变电压和浪涌幅度大大降低。浪涌防护的关键有两个，一个是防雷方案的设计，另一个重点就是浪涌防护器件的选择。硕凯电子作为具有十年以上防雷器件供应的电子防护专家，特意整理了一份防雷防护方案汇总，并附有相关防雷器件选型要点。

一、百兆网防雷方案

条件：

1. 网络耦合器内置于RJ45 座子内，但有中间抽头引出；

2. 要求通过通讯行业常规雷击等级，共模4kV，差模500V；

3. 无接大地条件。

方案：

如上图，网络耦合器T1内置在RJ45 座子里，中间抽头引出接RC滤波电路，放电管GDT并在RC电路两端；由于该放电管接在网络耦合器的抽头对地，所以此器件只能防护共模雷击。

网络耦合器后面是TVS1、TVS2，分别并在两组线路的两线间，用于抑制差模间的残压。

TVS 管后面是退耦电阻，加上可降低残压，减少雷击残压对后级芯片的损害；此电阻可以不添加。

方案器件：

1. GDT-陶瓷气体放电管：UN1812-90CSMD

2. TVS-瞬态抑制二极管：ESD03V32D-LC

方案等级：

国际标准 IEC61000-4-5 ( 10/700us ) 第四级共模：4kV 差模：0.5kV

二、485 防雷方案

条件：

1.工作电压5V。

2.通过2KV雷击测试。

3.需要过流保护。

4.无接大地条件。

方案：

如图，自恢复保险丝 PTC4、PTC5可以起到退耦和过流保护的作用；瞬态抑制二极管TVS7可以起到差模保护，若后级芯片差模残压承受能力强，可省略。

瞬态抑制二极管TVS4、TVS5可以起到共模保护作用，差模保护TVS7省略后可以起来差模保护，但残压会提高。

方案器件：

1. TVS-瞬态抑制二极管：SMBJ6.0CA

2. PTC-自恢复保险丝：SC250-120U

方案等级：

国际标准 IEC61000-4-5 （ 10/700us ）第四级差模2kV

三、I/O 接口防雷方案

条件：

1. 无接大地条件

2. 无特殊要求

方案：

如图，退耦电阻R6可以起来降低残压的作用，可以省略；瞬态抑制二极管TVS3可以钳位I/O口与工作地间的浪涌电压，反应时间在皮秒级、残压极低。

方案器件：

TVS-瞬态抑制二极管：SMBJ6.0CA

方案等级：

国际标准 IEC61000-4-5 （ 10/700us ）第四级差模：2kV

四、电源接口防雷方案

条件：

1. 输入电压12V。

2. 需要过流保护。

3. 需要防护雷击0.5kV。

方案：

如图，PTC3是过流保护自恢复保险丝，对于浪涌也可以起到退耦的作用；TVS6是过压保护瞬态抑制二极管，用于保护电源浪涌，非常常用。

方案器件：

1. PTC-自恢复保险丝： SCF60-050

2. TVS-瞬态抑制二极管：SMBJ15A

方案等级：

国际标准 IEC61000-4-5 （1.2/50us、8/20us 组合波）第二级差模 0.5kV

【应用】RJ45以太网接口的雷击保护方案

户外以太网容易遭受雷击，雷击浪涌产生的过电压和过电流会损坏以太网电磁兼容平衡，因此做好RJ45以太网接口的雷击保护方案十分必要。使用硕凯电子的GDT和TVS可以设计出符合802.11电气标准、满足IEC61000-4-5和GBT17626.5等浪涌测试标准以及IEC61000-4-2和GBT17626.2等静电测试标准的防护方案。

雷击浪涌防护指南——陶瓷气体放电管原理及应用

气体放电管因其具有较大的通流量，较小的极间电容，较长的寿命等优点，在浪涌防护中被广泛使用，一般作为保护电路的第一级防护器件。陶瓷气体放电管的电性能主要取决于电极间的气体介质，比如气体的种类、湿度、污染状况等。为了达到特定的电气参数，设计必须控制两个电极之间的距离和充气压力。
