This multiport line protector is designed as a single-package solution for protecting multiple twisted pair from overvoltage conditions. Based on a six-pin SOIC package, it is equivalent to four discrete DO-214AA packages. Available in surge current ratings up to 500 A for a 2x10 µs event, the multiport line protector is ideal for densely populated line cards that cannot afford PCB inefficiencies or the use of series power resistors.
For details of specific design criteria, see Figure 6.44, Figure 6.45, and Figure 6.46 in Section 6, “Reference Designs” of this Telecom Design Guide.
