The multiport MC line protector is an integrated, multichip solution for protecting multiple twisted pair from overvoltage conditions. It is intended for applications sensitive to load values. Typically, high speed connections require lower capacitance. CO values for the MC devices are 40% lower than standard UC devices Based on a six-pin surface mount SOIC package, it is equivalent to four discrete DO214AA or two TO-220 packages, which makes it ideal for densely populated, highspeed line cards that cannot afford PCB inefficiencies or the use of series power resistors. Surge current ratings up to 500 A are available.
