【经验】SIDACtor+MOV组合可实现低功耗、高可靠性浪涌防护,提供低电压钳位保护、将漏电流降至最低
浪涌防护设计有多种选择,设计工程师应了解每种选择的优缺点,包括过电压保护元件,例如金属氧化物电阻(MOV),瞬态电压抑制(TVS)二极管,气体放电管(GDT)以及用于交流电的保护晶闸管 (SIDAC)。本文将介绍LITTELFUSE的一种SIDACtor+MOV产品组合设计,对于低功耗和高可靠性需求,它是其浪涌防护的最佳选择。
在上述的四种保护元件中,TVS和MOV属于钳位型元件,而GDT和SIDAC为泄流型元件,Littelfuse推出的SIDACtor产品,具有低导通状态泄流电压和快速导通特性,对于高dv/dt或高di/dt浪涌,它的过冲电压最小,同时截止漏电流低。如图1所示,是Littelfuse的SIDACtor产品I-V曲线,在低于最大截止状态电压VDRM时,SIDACtor具有低漏电流IDRM。漏电流约为几微安。当电压达到器件的峰值击穿电压VS时,器件打开并切换到低保持电压VT。由于元件上的电压被短路在低电压下,SIDACtor可以支持大的瞬态电流,一个能够处理5000A峰值浪涌电流的SIDACtor可以被封装在一个标准的TO-218封装中,便于印刷电路板的布局。
图1 Littelfuse的SIDACtor产品I-V曲线示意图
将SIDACtor和MOV组合使用,为可能被高钳位电压损坏的电路提供低电压钳位保护,MOV的阻抗将瞬变后的最大电流降低至少五分之一,这会降低SIDACtor吸收的总瞬时能量,并确保SIDACtor得到保护。该组合的第二个重要优点是SIDACtor漏电流低于MOV自身的漏电流。对于必须满足低功耗标准的产品,在设备处于关闭状态或待机状态时,输入的SIDACtor+MOV组合浪涌防护将其产生的漏电流降至最低,对于最大化电源效率至关重要。
以电源产品为例,如图2所示,在输入整流前加入SIDACtor+MOV防护电路,考虑输入在AC220V±15%范围内波动,推荐采用Littelfuse的V275LA40BP+P3800MEL的组合方案。对该组合方案进行进一步浪涌测试,同时对比另外参数组合和单独的MOV方案,其参数对比如图2所示,从对比数据可以看出,V275LA40BP+P3800MEL的组合方案在Ir相对中等,但同时拥有更低的Vcl,考虑更好的保护后一级的功率器件,选择Vcl更低的V275LA40BP+P3800MEL组合方案,这样既能保证了低功耗,同时也更好的保护了后面的器件,降低了功率器件以及电容器件的成本。
图2 V275LA40BP+P3800MEL防护电路在电源输入应用电路图以及浪涌测试数据对比图
结合以上可以看出,MOV为SIDACtor的稳定防护提供保障,SIDACtor的低漏电流是低功耗的必要条件,二者的结合使用,是高可靠性和低功耗浪涌防护的最佳选择。

【应用】SIDACtor保护晶闸管应用于开关电源初级防护电路,可以提高电路的防护等级
Littelfuse是一家专注于电子保护期间研发生产的企业。它生产的SIDACtor系列保护晶闸管可以应对过压工况下的电路防护。本文为读者介绍SIDACtor MC系列晶闸管推荐电路在开关电源初级保护中的应用,这款产品有着低容抗的特点,能够不影响后级防护电路宽频带的特点。
【应用】基于硕凯电子的GDT、TVS和MOV设计的POE系统防雷保护方案
以太网供电技术(POE)的发展可简化用电设备的安装和部署,但由于工业以太网工作环境的严苛,对于POE端口的浪涌及静电防护必不可少。硕凯电子针对POE系统的防雷保护设计的方案,采用GDT在变压器前端做共模(八线)浪涌防护,网络变压器后级用小体积,低结电容的TVS1吸收差模能量,兼顾防护静电功能。
Littelfuse Introduces SMC Automotive Grade 3kA SIDACtor Pxxx0S3N-A for High Surge Current AC Power Line Protection
The Littelfuse new 3kA SIDACtor is the first thyristor-based product in the DO-214AB package to provide surge protection of 6kV/3kA (8/20µs). Previously, achieving such high surge ratings would require a significantly larger TO-262 package.
