The multiport line protector is an integrated multichip solution for protecting multiple twisted pair from overvoltage conditions. Based on a six-pin surface mount SOIC package, it is equivalent to four discrete DO-214AA or two TO-220 packages. Available in surge current ratings up to 500A, the multiport line protector is ideal for densely populated, high-speed line cards that cannot afford PCB inefficiencies or the use of series power resistors. SIDACtor devices are used to enable equipment to meet various regulatory requirements including GR 1089, ITU K.20, K.21, and K.45, IEC 60950, UL 60950, and TIA-968 (formerly known as FCC Part 68).Notes: All measurements are made at an ambient temperature of 25°C. IPP applies to -40°C through +85°C temperature range. IPP is a repetitive surge rating and is guaranteed for the life of the product. Listed SIDACtor® devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities. VDRM is measured at IDRM, and VS is measured at 100 V/µs. Off-state capacitance is measured between Pins 1-2 and 3-2 at 1 MHz with a 2 V bias and is a typical value for "UA" product. "UB" and "UC"capacitance is approximately 2x higher.
