RClamp0502N RailClamp Low Capacitance TVS Diode Array PROTECTION PRODUCTS - RailClamp Features Description The RailClamp series is a family of ultra low capaci- ESD protection for high-speed data lines to tance TVS arrays designed to protect high speed data IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) interfaces. This series has been specifically designed to IEC 61000-4-4 (EFT) 40A (5/50ns) protect sensitive components which are connected to Array of surge rated diodes with internal TVS Diode high-speed data and transmission lines from overvoltage Small package saves board space caused by ESD (electrostatic discharge), CDE (Cable Protects two I/O lines and a power line Discharge Events), and EFT (electrical fast transients). Low capacitance: 0.3pF typical They are designed for use in applications where board Low clamping voltage space is at a premium. Each device requires less than Solid-state silicon-avalanche technology 2 1.2mm of PCB area and will protect up to two high speed data lines. Mechanical Characteristics The monolithic design incorporates surge rated, low SLP1210N6 Package capacitance steering diodes and a TVS diode in a single RoHs/WEEE Compliant package. Each line has a typical capacitance of Nominal Dimensions: 1.2 x 1.0 x 0.58 mm <0.5pF to ground. The capacitance of each line is well matched for consistant signal balance. A connection Lead Pitch: 0.4mm to the TVS is provided for protection of external Lead Finish: NiPdAu voltage buses, such as those found in USB applica- Marking : Marking Code tions. This device is optimized for ESD protection of Packaging : Tape and Reel portable electronics. They may be used to meet the Applications ESD immunity requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge). USB The RClamp0502N is in a 6-pin, RoHS/WEEE compli- MMC Port ant, SLP1210N6 package. It measures 1.2 x 1.0 x Serial ATA 0.58mm. The small package makes it ideal for use in Video Port portable electronics such as cell phones, laptops, and digital still cameras.
