Axxxxu_4 Series - LCAS Asymmetrical Multiport SIDACtor® Device

DataSheet:SIDACTor Protection Thyristors Asym Multiport MS 013 Datasheet

This solid state SIDACtor® protection device 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 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/EIA-IS-968 (formerly known as FCC Part 68). Notes:

All measurements are made at an ambient temperature of 2 °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.
Vs is measured at 100 V/µs
Special voltage (Vs & Vdrm) and holding current (Ih) requirements are available upon request.
Off-state capacitance is measured at 1 MHz with a 2 V bias and is a typical value.
