uClamp3311P TM Low Voltage Clamp for ESD and CDE Protection TM PROTECTION PRODUCTS - MicroClampPROTECTION PRODUCTS Features Description TM 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 where low operating IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) voltage is vital. They offer superior electrical characteris- Cable Discharge Event (CDE) tics such as lower clamping voltage and no device Ultra-small package (1.0 x 0.6 x 0.5mm) degradation when compared to MLVs. They are de- Protects one data line signed to protect sensitive semiconductor components Low clamping voltage from damage or upset due to electrostatic discharge Working voltage: 3.3V (ESD), lightning, electrical fast transients (EFT), and Low leakage current cable discharge events (CDE). Solid-state silicon-avalanche technology TM The Clamp 3311P is constructed using Semtechs proprietary EPD process technology. The EPD process Mechanical Characteristics provides low standoff voltages with significant reduc- SLP1006P2 package tions in leakage currents and capacitance over silicon- RoHS/WEEE Compliant avalanche diode processes. They feature a true Nominal Dimensions: 1.0 x 0.6 x 0.5 mm operating voltage of 3.3 volts for superior protection Lead Finish: NiPdAu when compared to traditional pn junction devices. TM Molding compound flammability rating: UL 94V-0 The Clamp 3311P is in an 2-pin, RoHS/WEEE compli- Marking : Marking code, cathode band ant, SLP1006P2 package. It measures 1.0 x 0.6 x Packaging : Tape and Reel 0.5mm. The leads are spaced at a pitch of 0.65mm and are finished with lead-free NiPdAu. Each device Applications will protect one line operating at 3.3 volts. It gives the Cellular Handsets & Accessories designer the flexibility to protect single lines in applica- tions where arrays are not practical. They may be used Notebooks & Handhelds to meet the ESD immunity requirements of IEC 61000- Portable Instrumentation 4-2, Level 4 (15kV air, 8kV contact discharge). The Digital Cameras combination of small size and high ESD surge capability Peripherals makes them ideal for use in portable applications such MP3 Players as cellular phones, digital cameras, and MP3 players.
