【经验】金属氧化物压敏电阻和瞬态电压抑制二极管在浪涌防护电路中该怎么选?
金属氧化物压敏电阻(MOV)和瞬态电压抑制二极管(TVS)都是浪涌防护的常用器件,对提升电路的抗浪涌性能有着非常重要的作用。但两者导电机理和结构各有差异,因此在具体应用表现也不尽相同。本文将结合LITTELFUSE的MOV和TVS产品,从二者的导电机理、脉冲能量耗散机理、浪涌防护响应时间的不同进行讨论分析,从而更好的认识MOS和TVS在浪涌防护电路中的应用。
MOV是一种以ZnO为主体,添加多种金属氧化物,经电子陶瓷工艺制成的多晶半导体陶瓷器件,具有非线性导电特性,是抑制过电压、吸收浪涌能量的主要元器件。当施加电压小于击穿电压时,电压几乎全部加在压敏电阻上,其阻抗大于10MΩ,漏电流仅有微安级,当施加电压大于击穿电压时,其阻抗只有欧姆级,通过电流有几十安,其击穿时间只有几十到几百皮秒。如图1所示为Littelfuse的V130LA20A系列U/I曲线图,当电压小于130V时,随电压降低,漏电流逐渐减小,其最大阻抗达到109Ω;当电压大于130V时,随着电压增大,阻抗在1-10Ω左右。
图1 V130LA20A系列压敏电阻的U/I曲线图
TVS是在稳压管工艺基础上发展起来的一种新产品,具有非线性导电特性,是抑制过电压,ESD防护,分为单向和双向两种,目前TVS的PN结反向击穿电压一般大于6V。当施加电压小于反向击穿电压时,其导通电流与PN结势垒及温度有关;当施加电压大于反向击穿电压时,属于雪崩电子击穿导电,其导通电流只与所施加电压有关,雪崩电子击穿时间一般为1-2ns。当片式TVS两端经受瞬间浪涌高能量冲击时,他能够以纳秒级时间使其PN结阻抗降低,将其两端间的电压箝位在一个预定数值。如图2,以Littelfuse的SMAJ系列单向TVS为例,当施加电压小于反向击穿VBR时,TVS的PN结没有被击穿,其电流在VR为微安级别,当施加电压大于反向击穿VBR时,电压逐渐被箝位VBR,同时电流急剧上升到IPP,因此TVS主要是用于瞬态浪涌的箝位。
图2 SMAJ系列单向TVS的U/I曲线图
综合以上分析和对比,MOV和TVS均是浪涌防护的有效器件,如图3所示,针对不同的浪涌防护推荐的浪涌防护器件选型方案,TVS限制电压较低,瞬态内阻较小,适合应用于耐ESD电压特别差或者被保护部位阻抗特别小的部位(如通讯接口等)。而压敏电阻的吸收能量的能力比TVS管要强,除了一般的ESD防护,也特别适合于电源部位和较大瞬态能量的部位过压防护。在响应时间方面,要避免陷入MOV的响应时间慢的误区。由于工艺的差异,MOV的价格相对于TVS表现出良好的性价比,设计人员可以根据电路的实际应用灵活选择MOV或者TVS。
