【应用】国产TVS阵列用于尿液分析仪SD卡端口ESD防护，典型容值低至0.6pF

时间： 2021-03-04 来源：世强

技术问答

尿液分析仪中SD卡主要用于存储拍摄图像用，为避免尿液分析仪SD卡端口因热插拔或人体接触产生静电ESD导致SD卡相关敏感电子器件无法正常工作，一般需要对SD卡端口做静电防护设计，选型因素参考如下：

1、小体积：为满足尿液分析仪小型化设计需求，推荐选择集成TVS阵列，可同时对VCC、MISO、MOSI、CS、CLK等信号做防护；

2、高抗ESD能力：符合IEC 61000-4-2（ESD），4级（±15kV空气，±8kV接触放电）；

3、低结电容：避免高速数据传输出现数据丢包或传输数据错误；

针对如上设计需求，推荐硕凯电子TVS阵列SE05T5D15GA，典型结电容0.6pF，采用SOT-563封装，最大反向工作电压5V，接触放电能力达±8kV，空气放电能力±15kV，工作温度范围-55~150℃，典型应用电路参考如下图1所示。

图1：硕凯电子TVS阵列SE05T5D15GA典型电性参数

推荐硕凯电子TVS阵列SE05T5D15GA理由如下：

1、典型结电容低至0.6pF，避免高速数据传输出现数据丢包或传输数据错误；

2、采用SOT-563小尺寸封装，典型封装尺寸1.6x1.6mm，有助于小型化设计；

3、市面上有成熟的应用，产品性能得到验证，可靠性高；

4、世强平台常备库存，具有良好的供货交期，可以快速支持样品和量产服务。

【选型】静电保护器SE05T5D15GA可替换晶焱AZ2013-05R用于SIM做静电防护，结电容低至0.6pF

应用于SIM上防护的器件具有两个特点，一是产品小型化，二是产品可靠性的提高。从产品小型化分析，就需要构成产品的所有能缩小的部分进行缩小，器件封装的小型化自然带动产品的小型化、集成化。从可靠性上分析保护器件的保护能力强弱也直接影响产品的性能。因此本文推荐硕凯电子的静电保护器SE05T5D15GA替代晶焱的AZ2013-05R。
