技术问答

为了保障电源适配器的线路系统能够长时间高效安全工作，工程师就要在线路上做防护措施。压敏电阻在防护线路上是一种很常用的器件，它具有瞬态电压抑制功能，能防止静电放电、瞬态浪涌及其它突波干扰对线路造成的损坏。本文主要介绍硕凯10D471K压敏电阻应用于电源适配器，其具有大通流量，精准钳位特点。

在设计中一般会用在电源适配器的电源输入端，它能够对集成电路的重要元器件以及其它线路起到很好的防护作用，可延长设备的使用寿命，提高系统的可靠性。它并联在电路中，当电路正常工作时，它呈高阻抗状态。当电路中出现异常高压，达到它的击穿电压时，压敏电阻迅速由高阻抗变为低阻抗状态，将异常高压通过压敏电阻泄放并钳位在一个安全的电压值内，保证被保护电路不会因为电流过大而损坏。当异常消失时，它又恢复到高阻抗状态。

典型应用：

10D471K压敏电阻满足: IEC61000-4-5标准中 1.2/50US-8/20US 组合波2.5KV /1.25KA。

主要参数如下：

1、压敏电压U1mA（Varistor Voltage）：通常以在压敏电阻上通过 1mA直流电流时的电压来表示其是否导通的标志电压UN 。压敏电压也常用符号 U1mA表示。

2、通流量（Withstanding Surge Current），指压敏电阻能够承受的 8/20μs波的最大冲击电流峰值。

SOCAY硕凯压敏电阻20D561K在路灯电源输出端的浪涌防护，通流量可达6.5KA

硕凯电子推荐的20D561K，该器件采用的是插件封装，方便焊接，浪涌承受能力较强，通流量可达6.5KA，且留有一定的余量，低漏电流。对于AC220V电源输出口有较好的浪涌防护。

应用方案发布时间 : 2024-11-07

基于硕凯压敏电阻14D561K的IGBT快速开关电路，在浪涌抗干扰度试验中通过4级，且试验电压提高10%

本试验选用压敏电阻14D561K：击穿电压：504V-616V；通流量IPP高达4500A；位电压最大值 925V（50A）；工作温度：-55 至+125°C；具有通流量大、残压低、响应时间快等特点。当干扰电压达到一定值时，就会把两端的电压钳位住，从而保护IGBT不被击穿

【应用】国产压敏电阻14D561K用于LED路灯，通流量可达6KA

由于LED灯具有节能、响应时间短、使用寿命长、可直接替换传统灯等优点，所以LED灯的应用越来越广泛，现如今LED路灯也是随处可见。本篇主要讲述硕凯电子14D561K压敏电阻在LED路灯的应用，具有大通流量雷电在电源线路上产生感应浪涌，这个浪涌的能量会在电线上产生一个突波，即浪涌波，浪涌就是通过这样的感应方式进行传输的。

【经验】压敏电阻防雷的工作原理及特点

压敏电阻器相当于一个可变电阻，它是并联于电路中的，当电力线被雷击时，雷电波的高电压使压敏电阻击穿，雷电流通过压敏电阻流入大地，使电力线上的电压被钳制在安全范围内。压敏电阻的性能稳定、通流能力大，由于其突波承受能力取决于它的物理尺寸，因而有可能获得不同的浪涌电流值。

【应用】10D681K压敏电阻用于洗衣机电源，满足差模2KV的浪涌测试

在洗衣机电源控制板中，由于存在接入市电电压不稳定以及雷雨天气产生的感应雷会对开关电源造成不良影响。针对此问题，硕凯电子给出了一个性价比较高的防护方案，只需要在输入端加一级压敏电阻就可以解决以上问题。可以过1.2/50uS组合波差模2KV的浪涌测试，测试次数正负五次，间隔60秒。该方案用到了普通型的压敏电阻10D681K。
