瞬雷电子SMB封装大通流TVS：用于48V DC电源的小体积大通流物料
随着科学技术的不断发展，电子行业产品更新换代越来越快，对于器件的要求也越来越高，总体来说保护器件的发展趋势如下：
1）封装尽可能小，通流越大越好。即物料尽可能在小体积框架内实现较大的浪涌通流能力。
2）钳位电压要求越低越好，钳位电压越低，对后端芯片的保护效果越好。
3）集成化程度提高，更倾向多路保护器件，即实现相同防护效果下，保护器件物料用量越少越好。
瞬雷电子(SPSEMI)作为专业的电子元器件品牌商，设计了一款SMB（DO-214AA）封装大通流TVS。
NVS058B的规格参数如下：
NVS058B 主要特点:
1、采用SMB封装，浪涌通流IPP大小为760A；
2、反向截止电压为58V；
3、采用双向设计，不用区分器件极性。
NVS058B最大的特点是可以满足10/700μS组合波下4KV和8/20μS组合波下1.5KV雷击浪涌测试要求，按照该测试要求，使用传统的TVS管，至少需要选用3KW功率SMC封装物料才可以满足该浪涌测试要求，相比而言，SMC封装物料体积更大，更占PCB空间。
该物料主要用于DC 48V直流电源，实现单颗物料过较高等级浪涌测试要求：
或用于高浪涌等级做二级防护，降低后端残压：
也可直接用在POE电源上做浪涌防护：
