【应用】保护二极管阵列ESDALC208保障雷击时的数据通信安全，结电容仅7pF，可支持高数据传输速率

时间： 2023-08-03 来源：德欧泰克半导体公众号

技术问答

在炎热的夏季，雷暴中的雷击可构成相当大的危险。许多电子组件可能会在雷击中损坏。此类情况，令很多家用以太网路由器经常都要拆除更换。这不仅烦人且耗时，而且还会导致不必要的功耗。

DIOTEC推出的保护二极管阵列 ESDALC208包含八个ESD保护二极管，每个保护二极管串联连接。它可以保护四条数据线，免受静电放电（ESD）引起的过电压影响，例如在接线过程中出现的情况。由雷电或电快速瞬变（EFT）引起的过电流被引导至正或负基准电压，从而将过压限制在其最大的接受值。就只需两个部件就足以保护八线以太网线路及其接口。列阵中的每个二极管在1MHz时的结电容低至7pF，可支持高数据传输速率。
