protection products 1 www.semtech.com protection products - microclamp uclamp0511p clamp tm 1-line esd protection description features dimensions schematic & pin configuration revision 8/15/2008 the clamp tm series of tvs arrays are designed to protect sensitive electronics from damage or latch-up due to esd. it is designed to replace multilayer varistors (mlvs) in por- table applications. it features large cross-sectional area junctions for conducting high transient currents. it of- fers superior electrical characteristics such as lower clamping voltage and no device degradation when com- pared to mlvs. they offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degrada- tion. the clamp tm 0511p is in a 2-pin, rohs/weee compliant, slp1006p2 package. it measures 1.0 x 0.6 x 0.5mm. the leads are spaced at a pitch of 0.65mm and are finished with lead-free nipdau. each device will protect one bidirectional line operating at 5 volts. it gives the designer the flexibility to protect single lines in applications where arrays are not practi- cal. 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 ? cordless phones ? personal digital assistants (pdas) ? notebooks & handhelds ? 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 0.5mm) ? protects one i/o or power line ? low clamping voltage ? working voltage: 5v ? low leakage current ? solid-state silicon-avalanche technology ? slp1006p2 package ? molding compound flammability rating: ul 94v-0 ? marking : marking code ? packaging : tape and reel ? lead finish: nipdau ? rohs/weee compliant slp1006p2 (bottom view) maximum dimensions (mm) 0.65 0.50 0.60 1.0 2 1
