Image of Semtech's RClamp1255P Semtech's RailClamp® TVS arrays are low-capacitance ESD protection devices designed to protect high-speed data interfaces. The RClamp 1255P provides dedicated surge and ESD protection for µUSB ports. It is designed to replace multiple discrete components in portable applications. This device features low-capacitance TVS diodes for protection of the USB data (DP, DM) and USB ID pins operating up to ±4 V. These diodes provide ESD protection to ±10 kV contact discharge per IEC 61000-4-2. Loading capacitance on these lines is <0.50 pF. An integrated 12 V TVS diode is used for protection of the USB voltage bus. The V_BUS TVS is designed with a high-surge current capability of 100 A (t_p=8/20 µs) and low clamping voltage.

The RClamp1255P is in a 6-pin SLP2018P6 package. It measures 2.0 x 1.8 mm with a nominal height of 0.57 mm. 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 electronics.
