DESCRIPTION
RailClamp® TVS arrays are low capacitance ESD protection devices designed to protect high speed data interfaces. These diodes provide ESD protection to ±10kV contact discharge per IEC 61000-4-2. Loading capacitance on these lines is <0.50pF. An integrated 12 volt TVS diode is used for protection of the USB voltage bus. The VBus TVS is designed with a high surge current capability of 100A (tp=8/20us) and low clamping voltage. The RClamp1255P is in a 6-pin SLP2018P6 package. It measures 2.0 x 1.8mm with a nominal height of 0.57mm. This highly integrated device requires less board space than existing solutions. The combination of small size, low capacitance, and high level of surge and ESD protection makes this device a flexible solution for protection of USB interfaces in mobile phones, laptops, and other portable electonics.
