SR70中文资料先之科数据手册PDF规格书

描述 Description

RailClamps are surge rated diode arrays designed to protect high speed data interfaces. The SR70 has been specifically designed to protect sensitive components which are connected to data and transmission lines from over-voltages caused by ESD (electrostatic discharge), EFT (electrical fast transients), and lightning. The SR70 has been optimized for use on ADSL and other high-speed interfaces.
