protection products 1 www.semtech.com protection products - microclamp tm uclamp0511t low profile clamp tm 1-line esd protection description features dimensions schematic & pin configuration revision 07/1/2008 the clamp tm series of tvs arrays are designed to pro- tect sensitive electronics from damage or latch-up due to esd. it is designed to replace multilayer varistors (mlvs) in portable applications such as cell phones, note- book computers, and other portable electronics. it fea- tures large cross-sectional area junctions for conducting high transient currents. they offer desirable character- istics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. the clamp tm 0511t is in a 2-pin, rohs/weee compli- ant, slp1006p2t package. it measures 1.0 x 0.6 mm with a nominal height of only 0.4mm. the leads are spaced at a pitch of 0.65mm and are finished with lead-free nipdau. each device will protect one line operating at 5 volts. it gives the designer the flexibility to protect single lines in applications where arrays are not practical. they may be used to meet the esd immunity requirements of iec 61000-4-2, level 4 (15kv air, 8kv contact discharge). the 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. applications mechanical characteristics ? cellular handsets & accessories ? keypads, side keys, usb 2.0, lcd displays ? notebooks & desktop computers ? portable instrumentation ? digital cameras ? peripherals ? mp3 players ? transient protection for data lines to iec 61000-4-2 (esd) 15kv (air), 8kv (contact) iec 61000-4-4 (eft) 40a (tp = 5/50ns) cable discharge event (cde) ? ultra-small package (1.0 x 0.6 x 0.4mm) ? protects one data or power line ? low reverse current: 3na typical (vr=3.3v) ? working voltage: - 5v / +5v ? low capacitance: 4pf typical ? solid-state silicon-avalanche technology ? slp1006p2t package ? rohs/weee compliant ? nominal dimensions: 1.0 x 0.6 x 0.4 mm ? lead finish: nipdau ? molding compound flammability rating: ul 94v-0 ? marking : marking code, cathode band ? packaging : tape and reel slp1006p2t (bottom view) nominal dimensions (mm) 0.65 0.40 0.60 1.0 2 1
