The NP-SBMC series of Low Capacitance Thyristor Surge Protection Devices (TSPD) protect sensitive electronic equipment from transient overvoltage conditions. Due to their ultra low off-state capacitance (Co), they offer minimal signal distortion for high speed equipment such as ADSL2+, VDSL and T1/E1 circuits. The low nominal offstate capacitance translates into the extremely low differential capacitance offering superb linearity with applied voltage or frequency. These reliable silicon devices are also a suitable alternative to GDT protectors. The NP-SBMC Series helps designers to comply with the various regulatory standards and recommendations including: GR-1089-CORE, IEC 61000-4-5, ITU K.20/K.21/K.45, IEC 60950, TIA-968-A, FCC Part 68, EN 60950, UL 1950.
