RClamp1255P Low Capacitance RClamp Surge Protection for uUSB Interfaces PROTECTION PRODUCTS PRELIMINARY PROTECTION PRODUCTS - RailClamp Features Description ESD and surge protection for USB Voltage Bus to RailClamp TVS arrays are low capacitance ESD IEC 61000-4-2 (ESD) 30kV (air), 30kV (contact) protection devices designed to protect high speed data IEC 61000-4-5 (Lightning) 100A (8/20 s) interfaces. The RClamp 1255P provides dedicated IEC 61000-4-4 (EFT) 40A (5/50ns) surge and ESD protection for uUSB ports. It is de- ESD protection for USB data lines to signed to replace multiple discrete components in portable applications. This device features low capaci- IEC 61000-4-2 (ESD) 15kV (air), 10kV (contact) tance TVS diodes for protection of the USB data (DP, Protects USB DP, DM, and ID Pins operating up to DM) and USB ID pins operating up to +/- 4 volts. +/- 4V These diodes provide ESD protection to 10kV contact Protects USB VBus operating up to 12V discharge per IEC 61000-4-2. Loading capacitance on Low capacitance (<0.50pF) on DP, DM, and ID Pins these lines is <0.50pF. An integrated 12 volt TVS Low clamping voltage diode is used for protection of the USB voltage bus. Low dynamic resistance on DP, DM, and ID Pins The VBus TVS is designed with a high surge current Solid-state silicon-avalanche technology capability of 100A (tp=8/20us) and low clamping voltage. Mechanical Characteristics The RClamp1255P is in a 6-pin SLP2018P6 package. It SLP2018P6 6L package measures 2.0 x 1.8mm with a nominal height of 0.57mm. Pb-Free, Halogen Free, RoHS/WEEE Compliant This highly integrated device requires less board space Nominal Dimensions: 2.0 x 1.8 x 0.57 mm than existing solutions. Lead Finish: NiPdAu The combination of small size, low capacitance, and high Molding compound flammability rating: UL 94V-0 level of surge and ESD protection makes this device a Marking : Marking Code + Date Code flexible solution for protection of USB interfaces in mo- Packaging : Tape and Reel bile phones, laptops, and other portable electonics.
