DO-214AA SIDACtor solid state protection devices with a D surge rating protect telecommunications equipment located in hostile environments. These SIDACtor devices withstand the simultaneous surges outlined in GR 1089 lightning tests. (See “First Level Lightning Surge Test” on page 7-5.) Surge ratings are twice that of a device with a C surge rating. This provides a method for building an SMT version of the balanced ‘Y’ configuration. (US Patent 4,905,119) SIDACtor devices enable equipment to comply with various regulatory requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968-A (formerly known as FCC Part 68).
