The NP series of low voltage/low capacitance overvoltage protection devices protect high speed xDSL line drivers and chipsets from both Lightning Surge and ESD events. The devices are designed with a low nominal capacitance as well as extremely low differential capacitance across frequency and voltage. The inherent low off-state leakage current provides superior performance in low voltage high speed applications. These characteristics allow protection of the system without distortion of the high speed data signal. With it's advanced silicon structure the NP product is able to clamp very fast ESD events, and crowbar high energy surge events to help protect sensitive IC's all in a small footprint. The convenient flow thru design minimizes trace routing while maximizing circuit performance.
