TVS Diode Array 12 kV μUSB SP1255 Series

Littelfuse's SP1255P series low-capacitance, ESD protection, TVS diode arrays (SPA® Diodes) provide superior ESD protection for current-intensive applications, such as fast-charging peripherals or PoweredUSB. They integrate three channels of ultra-low capacitance steering diodes with a low voltage TVS diode to provide maximum ESD protection of the USB data and ID pins. With a dynamic resistance of just 0.3 Ω, they provide clamping voltages up to 23 percent lower than similar silicon solutions. A high-surge current protection device with a working voltage of 12 V is allocated for V_BUS protection against lightning-level-fast transients on the USB V_BUS line up to 100 A. Typical applications include ESD protection for smartphones, tablets, and other portable electronics.
