Designed with miniaturized integrated packages for mobile devices, the ESD105 series addresses TVS for high-speed data interfaces, such as USB 3.0, Gbit Ethernet, Firewire and HDMI links used in desktop computers, TV sets and portable electronics. Being located at the surface of a device, these interfaces are especially sensitive to ESD. A mere touch of the hand can be sufficient to induce an electric current, and the energy generated by the discharge can damage the equipment or even render it completely unserviceable.

With very-low clamping voltage (10V at 8kV) and ultra-low capacitance (C = 0.3pF) the ESD105 TVS diodes (single line) enable engineers to achieve strict requirements for ESD robustness and signal quality of the high-speed interfaces used in the latest generation smartphones and tablet computers. The new series provides protection that exceeds the specifications of IEC61000-4-2 in 2-pin packages (0201, 0402). The leakage current is under 20nA, contributing to longer system battery life. A dedicated pad-layout keeps PCB layout simple and minimize parasitic effects.
