uClamp2501T Low Voltage Clamp 2.5V TVS Diode 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 Low leakage current: <10nA typical (VR=2.5V) MLVs. They are designed to protect sensitive semicon- Low Operating voltage: 2.5V ductor components from damage or upset due to Low capacitance electrostatic discharge (ESD), lightning, electrical fast Protects one data line transients (EFT), and cable discharge events (CDE). Solid-state silicon-avalanche technology The Clamp 2501T is constructed using Semtechs proprietary EPD TVS process technology. The EPD Mechanical Characteristics process provides low operating voltages with significant SLP1006P2T package reductions in leakage currents and capacitance over Pb-Free, Halogen Free, RoHS/WEEE Compliant silicon-avalanche diode processes. They feature a true Nominal Dimensions: 1.0 x 0.6 x 0.4 mm sub 5 volt operating voltage for superior protection Lead Finish: NiPdAu when compared to traditional pn junction devices. Molding compound flammability rating: UL 94V-0 The Clamp2501T is in a 2-pin SLP1006P2T package. Marking : Marking code, cathode band 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.
