RClamp0522T RClamp0524T Ultra Low Capacitance TVS Arrays PROTECTION PRODUCTS PRELIMINARY PROTECTION PRODUCTS - RailClamp Features Description RailClamps series consists of ultra low capacitance ESD protection for high-speed data lines to TVS arrays designed to protect high speed data inter- IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) faces. This series has been specifically designed to IEC 61000-4-5 (Lightning) 5A (8/20 s) protect sensitive components which are connected to IEC 61000-4-4 (EFT) 40A (5/50ns) high-speed data and transmission lines from overvolt- Package design optimized for high speed lines age caused by ESD (electrostatic discharge), CDE Flow-Through design (Cable Discharge Events), and EFT (electrical fast Protects two or four I/O lines transients). Low capacitance: 0.3pF typical (I/O to I/O) The RClamp 0522T and RClamp 0524T have a typical Low clamping voltage capacitance of only 0.30pF between I/O pins. This Low operating voltage: 5V allows it to be used on circuits operating in excess of Solid-state silicon-avalanche technology 3GHz without signal attenuation. They may be used to Mechanical Characteristics meet the ESD immunity requirements of IEC 61000-4- 2, Level 4 (15kV air, 8kV contact discharge). The SLP1610P4T 6-pin package (1.6 x 1.0 x 0.40mm) RClamp0522T is designed to protect two lines, while SLP2510P8T 10-pin package (2.5 x 1.0 x 0.40mm) the RClamp0524T will protect four lines. Pb-Free, Halogen Free, RoHS/WEEE Compliant The RClamp0522T is in a 6-pin, SLP1610P4T package. Lead Pitch: 0.5mm It measures 1.6 x 1.0 with a nominal height of 0.4mm. Lead finish: NiPdAu The RClamp0524T is in a 10-pin, SLP2510P8T package. Marking: Marking Code It measures 2.5 x 1.0 with a nominal height of 0.4mm. Packaging: Tape and Reel The leads are spaced at a pitch of 0.5mm and are fin- ished with lead-free NiPdAu. They are designed for easy Applications PCB layout by allowing the traces to run straight through High Definition Multi-Media Interface (HDMI) the device. The combination of small size, low capaci- Digital Visual Interface (DVI) tance, and high level of ESD protection makes them a TM DisplayPort Interface flexible solution for applications such as HDMI, TM MDDI Ports DisplayPort , MDDI, and eSATA interfaces.
