uClamp3305P Low Voltage TVS for ESD Protection TM PROTECTION PRODUCTS - MicroClampPROTECTION PRODUCTS Features Description TM The Clamp series of TVS arrays are designed to Transient protection for data lines to protect sensitive electronics from damage or latch-up IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) due to ESD, lightning, and other voltage-induced IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) transient events. Each device will protect up to four Small package for use in portable electronics lines operating at 3.3 volts. Protects five I/O lines Working voltage: 3.3V TM The Clamp 3305P is a solid-state device designed Low leakage current specifically for transient suppression. It is constructed Low operating and clamping voltages using Semtechs proprietary EPD process technology. Solid-state silicon-avalanche technology The EPD process provides low standoff voltages with significant reductions in leakage currents and capaci- Mechanical Characteristics tance over traditional pn junction processes. They offer SLP1616P6 package desirable characteristics for board level protection RoHS/WEEE Compliant including fast response time, low clamping voltage and no device degradation. Nominal Dimensions: 1.6 x 1.6 x 0.58 mm Lead Pitch: 0.5mm The Clamp3305P may be used to meet the immunity Lead Finish: NiPdAu requirements of IEC 61000-4-2, level 4 (15kV air, Marking : Orientation Mark and Marking Code 8kV contact discharge). It is packaged in an ultra Packaging : Tape and Reel small SLP1616P6 package with a low profile of only 0.58mm. The leads are spaced at a pitch of 0.5mm Applications and are finished with lead-free NiPdAu. The small Cellular handsets and accessories package makes it ideal for use in portable electronics Notebooks and handhelds such as cell phones, digital still cameras, and notebook MP3 Players computers.
