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 500A for a 2x10µs event, the multiport line protector is ideal for densely populated line cards that cannot afford PCB inefficiencies or the use of series power resistors.

  • 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 & surge ratings apply to forward and reverse polarities.
  • Vdrm is measured at Idrm.
  • Vs is measured at 100V/µs.
  • Special voltage (Vs & Vdrm) and holding current (Ih) requirements are available upon request.
  • Off-state capacitance is measured across pins 1-2, 2-3, 4-5, or 5-6 at 1 MHz with a 2V bias and is a typical value. Capacitance across pins 1-3 or 4-6 is approximately half. “UC” capacitance is approximately 2x the listed value for “UA” product.
  • Parallel capacitive loads may affect electrical parameters.
