PROECION PRODUCS - Z-Pak M Description RailClamp S arrays are ultra low capacitance ESD protection devices designed to protect high speed data interfaces. hey are designed to replace 00 size multilayer varistors (MLs) in portable applications such as cell phones, notebook computers, and other portable electronics. his device offers desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. RClamp 8Z has a maximum capacitance of only 0.8pF. his allows it to be used on circuits operating in excess of 3GHz without signal attenuation. RClamp8Z is in a -pin SLP0603PX3B package. It measures 0.6 x 0.3 mm with a nominal height of only 0.mm. Leads are finished with lead-free NiAu. Each device will protect one line operating at 8 volts. It gives the designer the flexibility to protect single lines in applications where arrays are not practical. he combination of small size and high ESD surge capability makes them ideal for use in portable applications such as cellular phones, digital cameras, and MP3 players.
