The three-chip modified TO-220 SIDACtor® balanced solid state device is designed for telecommunication protection systems that reference Tip and Ring to earth ground. Applications include any piece of transmission equipment that requires balanced protection. This device is built using Littelfuse's patented "Y" (US Patent 4,905,119)configuration. The SIDACtor device is 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. VS is measured at 100 V/µs. Special voltage (VS and VDRM) and holding current (IH) requirements are available upon request. 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 product. and capacitance is approximately 2x the listed value. Device is designed to meet balance requirements of GTS 8700 and GR 974.
