SEMTECH RCLAMP0502N.TCT

The RailClamp series is a family of ultra low capacitance TVS arrays designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). They are designed for use in applications where board space is at a premium. Each device requires less than 1.2 mm² of PCB area and will protect up to two high speed data lines. The monolithic design incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. Each line has a typical capacitance of <0.5 pF to ground. The capacitance of each line is well matched for consistant signal balance. A connection to the TVS is provided for protection of external voltage buses, such as those found in USB applications. This device is optimized for ESD protection of portable electronics. They may be used to meet the ESD immunity requirements of IEC 61000 - 4 - 2, Level 4 (±15 kV air, ±8 kV contact discharge). The RClamp0502N is in a 6 - pin, RoHS/WEEE compliant, SLP1210N6 package. It measures 1.2×1.0×0.58 mm. The small package makes it ideal for use in portable electronics such as cell phones, laptops, and digital still cameras.
