【应用】TVS管SE03N2C01HZ用于NB-IOT模块天线ESD防护,结电容仅0.4pF,防护等级±20kV
NB-IOT模块作为物联网终端节点,广泛应用于农牧业、远程抄表、智能家居和智慧城市等领域。由于静电放电(ESD)现象无处不在,瞬间产生的浪涌经过NB-IOT天线会对后一级的处理芯片造成损伤,因此需要在NB-IOT天线增加保护器件。
针对NB-IOT模块天线ESD静电防护应用,推荐硕凯的TVS(瞬态抑制二极管)SE03N2C01HZ,最大反向保持电压3.3V,击穿电压7V,最大漏电流1uA,ESD防护等级满足IEC61000-4-2标准±20kV(接触放电)/±15kV(空气放电),以下是SE03N2C01HZ的主要电气参数:
SE03N2C01HZ内部只有一个TVS二极管,采用固态硅工艺设计,根据IEC61000-4-2,它可用于提供高达±20kV(接触放电)/±15kV(空气放电)的ESD保护,根据IEC61000-4-5,可承受4A(8/20us)的峰值脉冲电流,保护天线后端芯片免受静电损伤;由于天线通常会有匹配电路,因此对ESD器件等效电容要求低,否则会影响天线正常匹配,SE03N2C01HZ的结电容只有0.4pF,能有效降低TVS非线性参数对天线的影响; SE03N2C01HZ的封装是DFN0603,尺寸小,适合NB-IOT模块等内部空间有限的防护电路设计,以下是典型封装和内部结构图:
图1 SE03N2C01HZ典型封装和内部框图
综上所述,硕凯的TVS二级管SE03N2C01HZ具有小封装尺寸、结电容0.4pF、防静电能力±20KV(接触放电)/±15KV(空气放电)的特性,同时具有国产低成本优势,是NB-IOT模块等物联网设备天线保护电路的优秀解决方案。
