The low-capacitance SP2574NUTG TVS diode array from Littelfuse protects high-speed, differential data lines from damage due to ESD (electrostatic discharge), CDE (cable discharge events), EFT (electrical fast transients), and lightning-induced surges. It can protect up to four channels or two differential pairs at up to 40 A (IEC61000-4-5) and up to 30 kV ESD (IEC61000-4-2). Its low capacitance (just 3.8 pF (typ.) from I/O to ground) and low clamping voltage (15 percent lower at 40 A than other competitive solutions) make it ideal for protecting high-speed data interfaces, such as 1 GbE applications found in notebooks, switches, and servers. It is also well-suited for use in WAN/LAN equipment, LVDS interfaces, integrated magnetics, and Smart TV applications.
