保护应用：

The signals used in the Subscriber Identification Module (SIM) circuit include Data, Clock and Reset. Since the SIM card can be removed by the user, there is an ESD to the SIM interface socket.

解决方案说明：

A single, space efficient TVS diode array can also be used. The SP3002-04UTG is shown; if a device with greater ESD capabilities is desired, the SP1011-04UTG can be used. MLA Series Multilayer Varistors (MLVs) or SP0503 series SPA TVS Diode Arrays may also be used.

配套解决方案：

监管问题：

IEC 61000-4-2是最适合此接口的标准规范。 通过该测试可证明终端产品不易受到ESD危害。
