——为超高清电视，LCD/PDP/电视和销售点显示屏提供经济的保护

全球领先的电路保护领导厂商LITTELFUSE公司推出了一系列TVS 二极管阵列（SPA二极管），旨在保护受到破坏性静电放电（ESD）的电子设备的每个I/O引脚）或电快速瞬变（EFT）。新的SP1064系列TVS二极管阵列是使用专有的硅雪崩技术制造的齐纳二极管。这些稳健的二极管可以安全地吸收高于IEC 61000-4-2国际标准规定的最大电平的重复ESD冲击，而不会降低性能。它们的非常低的负载电容（通常为每I/O为8.5pF）也使其成为保护高速信号引脚的理想选择。

SP1064系列的典型应用包括为超高清电视，LCD/PDP/电视，台式机/笔记本电脑和销售点显示屏的背光和边缘照明解决方案提供保护。

Littelfuse TVS二极管阵列（SPA二极管）全球产品经理Tim Micun表示：“SP1064系列TVS二极管为电路设计人员提供了经济地保护高达15个高亮度LED（HBLED）的串对ESD和EFT的能力。“这确保了较低的总体保护预算，同时仍然提供高水平的保护。

SP1064系列TVS二极管具有以下主要优点：

1）高隔离电压（高达60V）使其能够在ESD和EFT的超高清电视中保护背光或边缘照明中使用的高达15个HBLED的串。

2）每个四线DFN阵列允许保护多达四行LED串。单个四线设备足以用于较小的轮廓显示，而大格式显示器每个象限只需要一个设备。

3）对于8/20μsESD事件，至少有15kV接触保护，使SP1064系列能够提供比市场上类似TVS二极管更大的ESD保护。

4）行业标准uDFN-10封装使得解决方案成本低廉，拥有成本低。
