SP4337 is specifically designed to protect high-speed interfaces against ElectroStatic Discharge (ESD), such as High-Definition Multimedia Interface (HDMI) and DisplayPort interfaces, Thunderbolt and USB 3.1 Gen 1. The signal line is protected by a TVS diode offering low line capacitance of 0.18 pF typical. SP4337 can safely absorb repetitive ESD strikes up to ±15 kV contact exceeding IEC 61000-4-2, level 4 ( ±8kV contact discharge). Excellent low capacitance, clamping capability, low leakage, and fast response time make this parts an ideal solution for protecting high speed data lines.
