Description

The NSP8814 and NSP8818 surge protection devices are designed specifically to protect 10/100 and GbE Ethernet signals from high levels of surge current. Low clamping voltage under high surge conditions make this device an ideal solution for protecting voltage sensitive lines leading to Ethernet transceiver chips. Low capacitance combined with flow-through style packaging allows for easy PCB layout and matched trace lengths necessary to maintain consistent impedance between high-speed differential lines. The integrated 4 and 8 lines of protection in flow-thru type packages offer a simplified solution with premier performance for 10/100 and GbE Ethernet applications.
