CXPR7857W是一种低电容TVS（瞬态电压抑制器）阵列，用于保护高速数据接口。它专门设计用于保护连接到数据和传输线的敏感电子元件，使其免受静电放电（ESD）、电缆放电事件（CDE）、雷电和其他感应电压浪涌造成的过应力。
CXPR7857W采用低电容转向二极管，可将每条线路的典型电容降低至1pF。
根据IEC61000-4-2，CXPR7857W可用于提供高达±30kV（接触放电）的ESD保护，并根据IEC61000-4-5承受高达20A（8/20μs）的峰值脉冲电流。
CXPR7857W在SOD-323软件包中提供。标准产品无铅无卤。

一.产品概述
The CXPR7857W is a low capacitance TVS (Transient Voltage Suppressor) array designed to protect high speed data interfaces. It has been specifically designed to protect sensitive electronic components which are connected to data and transmission lines from over-stress caused by Electrostatic Discharge (ESD), cable discharge events (CDE), lightning and other induced voltage surges.
The CXPR7857W incorporates low capacitance steering diodes that reduce the typical capacitance to 1pF per line.
The CXPR7857W may be used to provide ESD protection up to ±30kV (contact discharge) according to IEC61000-4-2, and withstand peak pulse current up to 20A (8/20μs) according to IEC61000-4-5.
The CXPR7857W is available in SOD-323 package. Standard products are Pb-free and Halogen-free.
