保护应用：

Keypads and various buttons can be an entry way for ESD into an application. These circuits are low-voltage DC switches, typically less than 5VDC, so capacitance is not a concern.

解决方案说明：

The examples contain four lines for demonstration purposes. 实际应用时的线路数量可能有所变化。 A single diode array cab be used to reduce part count. Discrete diodes can also be used to provide the greatest board layout flexibility.

配套解决方案：

除了上述建议外，LF产品组合中还提供了其它解决方案。 For example, if discrete diodes with smaller footprint are desired, the SP1005-01WTG (0201) can be used.

监管问题：

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

特性：
