uClamp2511T Low Profile Clamp 1-Line ESD protection PROTECTION PRODUCTS PROTECTION PRODUCTS - MicroClamp Features Description The Clamp series of Transient Voltage Suppressors Transient protection for data lines to (TVS) are designed to replace multilayer varistors IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) (MLVs) in portable applications such as cell phones, IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) notebook computers, and PDAs. They offer superior Cable Discharge Event (CDE) electrical characteristics such as lower clamping Ultra-small package (1.0 x 0.6 x 0.4mm) voltage and no device degradation when compared to Protects one data line MLVs. They are designed to protect sensitive semicon- Low reverse current: 10nA typical (VR=2.5V) ductor components from damage or upset due to Working voltage: 2.5V electrostatic discharge (ESD), lightning, electrical fast Low leakage current transients (EFT), and cable discharge events (CDE). Solid-state silicon-avalanche technology The Clamp 2511T is constructed using Semtechs proprietary EPD process technology. The EPD process Mechanical Characteristics provides low standoff voltages with significant reduc- SLP1006P2T package tions in leakage currents and capacitance over silicon- Pb-Free, Halogen Free, RoHS/WEEE Compliant avalanche diode processes. They feature a true Nominal Dimensions: 1.0 x 0.6 x 0.4 mm operating voltage of 2.5 volts for superior protection Lead Finish: NiPdAu when compared to traditional pn junction devices. Molding compound flammability rating: UL 94V-0 The Clamp2511T is in a 2-pin SLP1006P2T package. Marking : Marking code It measures 1.0 x 0.6 x 0.4mm. The leads are spaced Packaging : Tape and Reel at a pitch of 0.65mm and are finished with lead-free NiPdAu. Each device will protect one line operating at Applications 2.5 volts. It gives the designer the flexibility to protect single lines in applications where arrays are not practi- Cellular Handsets & Accessories cal. They may be used to meet the ESD immunity Portable Instrumentation requirements of IEC 61000-4-2, Level 4 (15kV air, Keypads, Side Keys, LCD Displays 8kV contact discharge). The combination of small Notebooks & Desktop Computers size and high ESD surge capability makes them ideal MP3 Players for use in portable applications such as cellular phones, digital cameras, and MP3 players.
