为什么用氧化锌压敏电阻MLV替代TVS齐纳二极管?
更低的寄生电容,更快的反向恢复速度
简单地说,瞬变抑制器的作用是减少电压尖峰的幅度,从而起到保护敏感的集成电路、晶体管和其他敏感器件免受瞬间电压尖峰的损害。这些瞬态尖峰可能是外部引起,如ESD,EFT、雷电浪涌,或在应用程序本身,如感应负载的开关引起的,或者是为测试电路的抗EMC水平而人为的制造的。
目前市场上采用的瞬变抑制器主要有:以硅材料技术为代表的ESD保护器件,如瞬态电压抑制器TVS二级管;以氧化锌材料技术为代表的ESD保护器件,如多层氧化锌压敏电阻MLV;以高分子聚合物技术为代表的ESD保护器件。
金属氧化物压敏电阻采用的是一个陶瓷无铅表面贴装的特殊封装形式,这些技术增加了其性能,对于工程师来说,可以更大可能的减小PCB的尺寸,同时也为一些有特殊要求的设计提供了可能,是替代TVS型齐纳二极管的理想选择。对于工程师来说,使用氧化锌压敏电阻MLV替代TVS型齐纳二极管,首先需要了解其基本性能和优势。
氧化锌压敏电阻MLV和齐纳二极管无论是物理性能还是电气性能都有所不同,所以在设计上进行直接的替换是存在风险的,同样对于两种不同技术参数直接对比也不切实际,所以下面我们将对二者在应用设计进行分析介绍。
哪些类型的齐纳二极管可以被MLV替代
典型的是300-1500W的常规工业应用齐纳二极管,表1所示的是一些工业应用的齐纳二极管,用于瞬态电压抑制的MLV是不能用于替代用于稳压的齐纳二极管。
表1:常规TVS型齐纳二极管
封装形式 | 300W | 400W | 600W | 1500W |
通孔 | SA | SA、P4KA | ||
表面贴装 | SM4、TPSMA | 1SMB、SMBJ、SM6、P6SMB | 1SMC、SMCJ、SM15、1.5SMC、TPSMC |
相对于TVS管MLV的优势
1、具有更低的寄生电容:氧化锌压敏电阻MLV寄生电容的范围可以从几十到几百皮法。齐纳二极管也一样,它基本上是与额定电压(通常,ML氧化锌材料厚度增加,电压)成反比的。对于低压,氧化锌压敏电阻MLV电容值一般会高些,但会低于TVS管,因此这取决于产品种类。在实际应用中,如果上述类型的TVS管额定齐纳是使用在一个特定的应用程序中, 氧化锌压敏电阻MLV在交流电路应用中常常不影响,一些标准版本的氧化锌压敏电阻MLV通过减少电极层数来降低寄生电容。读者可以通过数据手册里的参数选取器件,世强也可以提供LITTELFUSE定制的有特定寄生电容需求的产品。
2、更快的反向恢复速度:氧化锌压敏电阻MLV和齐纳表现出极好的快速上升响应的瞬变电压变化响应能力,响应时间低至几纳秒到几十微秒。Littelfuse 氧化锌压敏电阻MLV本身在纳秒响应。在实际应用中,总响应时间将取决于电路参数和冲击电流的大小。无铅氧化锌压敏电阻MLV器件无外围引线有效的降低了引线电感。考虑到IEC的ESD瞬变模型,在这种极端情况下di/ dt波阵面之间有冲击有时1纳秒的电流上升时间,要求与标准的2欧姆负载和合成的dv / dt的电压波形发生器电路进行对比。

【应用】通过双标准认证保护器件,给RJ45接口穿上“防弹衣”
SLVU2.8-4满足IEC61000-4-2和IEC61000-4-5标准,结电容C<2pF。
【应用】Vrwm为15V!这款保护器件大幅度超出ESD标准
Vrwm为15V,大幅度超出ESD测试标准,具有更强的保护能力,且设计简单。
【经验】Littelfuse 推出的工业金属氧化物压敏电阻(MOV)实际使用中的关键注意事项
Littelfuse提供工业金属氧化物压敏电阻(MOV),以解决工业环境中的过压瞬变问题。其主要用于感应闪电浪涌或用于调节由电机本身产生的瞬变。 这些情况要求MOV额定值与相应位置发生的的浪涌相匹配,具有适当的高能量和浪涌电流值。 本文说明了关于应用于工业交流线路的Littelfuse金属氧化物压敏电阻的重要注意事项,并给出了电机保护示例。
【选型】力特全新压敏电阻四种系列等你选择
力特(Littelfuse)提供了四个系列的压敏电阻,包括MA系列轴向引线式压敏电阻、RA系列小尺寸压敏电阻、C-III系列高能径向引线式压敏电阻和FBMOV系列无碎片热保护压敏电阻,均无铅、无卤素且浪涌能力强,可以广泛的应用于汽车、电机控制等领域中的过热、过流保护。
【产品】Littelfuse符合UL和CSA认证的LRU系列保险丝减压器,适用于通信设备、工业电子、汽车电子等
Littelfuse推出的LRU系列保险丝减压器,允许将较小尺寸的保险丝安装到现有的保险丝夹中,以防止过度熔断,广泛应用于通信设备、工业电子、汽车电子、消费电子等领域。
正温度压敏电阻TMOV20RP175M和普通的压敏电阻有何区别?
正温度压敏电阻TMOV20RP175M内含有一个正温度的保险丝,当浪涌电流非常大会造成压敏电阻失效短路,这时正温度保险丝会被熔断,不会影响到后级电路安全,而普通的压敏电阻则不具备这种功能。
