Transcription

1 - RailClamp Description RClamp 351P provides ESD protection for USB3. and other high-speed ports. It may be used to meet the ESD immunity requirements of IEC is designed to minimize both the ESD peak clamping and the TLP clamping. The dynamic resistance is minimized (.47 Ohms typical) for optimum protection of sensitive circuits. Maximum capacitance is only.4pf. This allows the to be used in applications operating in excess of 5GHz without appreciable signal attenuation. These devices are manufactured using Semtech s proprietary low voltage technology for superior electrical characteritics. is in a -pin SLP16P package. It measures 1. x.6 x.5mm. Leads are spaced at a pitch of.65mm and are finished with lead-free NiPdAu. Each device will protect one line operating up to 3.5 volts. The combination of low peak ESD clamping, low dynamic resistance, and low capacitance makes this device suitable for applications such as USB 3., audio and -By- One interfaces in portable devices.
