uClamp1211T TM Low Profile Clamp 1-Line ESD protection TM PROTECTION PRODUCTS - MicroClampPROTECTION PRODUCTS Features Description TM The Clamp series of TVS arrays are designed to pro- Transient protection for data lines to tect sensitive electronics from damage or latch-up due IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) to ESD. It is designed to replace multilayer varistors IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) (MLVs) in portable applications such as cell phones, note- Cable Discharge Event (CDE) book computers, and other portable electronics. It fea- Ultra-small package (1.0 x 0.6 x 0.4mm) tures large cross-sectional area junctions for conducting Protects one data or power line high transient currents. They offer desirable character- Low reverse current: <1nA typical (VR=12V) istics for board level protection including fast response Working voltage: - 12V / +12V time, low operating and clamping voltage, and no device Low capacitance: 3pF typical degradation. Solid-state silicon-avalanche technology TM The Clamp 1211T is in a 2-pin, RoHS/WEEE compli- ant, SLP1006P2T package. It measures 1.0 x 0.6 mm Mechanical Characteristics with a nominal height of only 0.4mm. The leads are SLP1006P2T package spaced at a pitch of 0.65mm and are finished with RoHS/WEEE Compliant lead-free NiPdAu. Each device will protect one line Nominal Dimensions: 1.0 x 0.6 x 0.4 mm operating at 12 volts. It gives the designer the flexibil- Lead Finish: NiPdAu ity to protect single lines in applications where arrays are not practical. They may be used to meet the ESD Molding compound flammability rating: UL 94V-0 immunity requirements of IEC 61000-4-2, Level 4 Marking : Marking code, cathode band (15kV air, 8kV contact discharge). The combination Packaging : Tape and Reel of small size and high ESD surge capability makes them ideal for use in portable applications such as Applications cellular phones, digital cameras, and MP3 players.
