【产品】SMC封装的大通流TVS管UNS2K30CA,最大峰值电流2KA@8/20μs,适用于24V电源系统
优恩半导体推出的大通流TVS管UNS2K30CA适用于12V电源系统,符合IEC61000-4-5 雷击浪涌高等级测试。其瞬态脉冲峰值电流可达2000A@8/20μs,抗浪涌能力高达4KV。大小仅为SMC常规封装,真正做到小封装,大能量。
【经验】如何根据通信产品电源推荐合适的端口保护器件
那么人们在面对这些通信产品电源及端口,是选ESD静电二极管、TVS管还是放电管,加不加压敏电阻或者PPTC自恢复保险丝呢,还是只用其他的一个,要不要搭配一起用,首先要先了解这些产品,然后才能推荐合适的保护元器件。
UNS2K系列表面贴装瞬态电压抑制器数据表
该资料介绍了表面贴装瞬态电压抑制器(TVS)的系列产品,特别是UNS2K系列的特性。这些TVS设计用于直流电源设备的户外暴露环境中,旨在替代传统的PTC、GDT和TVS组合解决方案。它们适用于DC24V、DC12V端口等,具有玻璃钝化结点、优异的钳位能力、低重复率、低剖面尺寸和高脉冲功率处理能力。
