RClamp3321P Ultra-Low Capacitance 1-Line, 3.3V ESD protection PROTECTION PRODUCTS - RailClamp Description Features The RClamp 3321P provides ESD protection for USB3.0, u Transient protection for data lines to IEC 61000-4-2 (ESD) 17kV (air), 12kV (contact) HDMI1.3/1.4, and other high-speed ports. It may be IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) used to meet the ESD immunity requirements of IEC Cable Discharge Event (CDE) 61000-4-2. The RClamp3321P is designed to minimize u Ultra-small package (1.0 x 0.6 x 0.5mm) both the ESD peak clamping and the TLP clamping. The u Protects one data or I/O line dynamic resistance is minimized (0.47 Ohms typical) for u Low capacitance: 0.35pF optimum protection of sensitive circuits. Maximum ca- u Dynamic Resistance: 0.47 Ohms Typical pacitance is only 0.35pF. This allows the RClamp3321P u Low ESD clamping voltage to be used in applications operating in excess of 5GHz u Operating voltage: 3.3V without signal attenuation. These devices are manufac- u Solid-state silicon-avalanche technology tured using Semtechs proprietary low voltage technol- ogy for superior characteritics at operating voltages up Mechanical Characteristics to 3.3 volts. u SLP1006P2 package The RClamp3321P is in a 2-pin SLP1006P2 package. It u Molding compound ammability rating: UL 94V-0 measures 1.0 x 0.6 x 0.5mm. The leads are spaced at a u Marking: Marking code pitch of 0.65mm and are nished with lead-free NiPdAu. u Packaging: Tape and Reel Each device will protect one line operating at 3.3 volts. u Lead Finish: NiPdAu The combination of low peak ESD clamping, low dynamic u Pb-Free, Halogen Free, RoHS/WEEE Compliant resistance, and low capacitance makes this device suit- able for applications such as USB 3.0, HDMI and V-By- One interfaces in portable devices.
