uClamp0508T TM Low Profile Clamp 8-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 tures large cross-sectional area junctions for conducting Protects eight data lines high transient currents. TVS diodes offer desirable char- Low clamping voltage acteristics for board level protection including fast re- Working voltage: 5V sponse time, low operating and clamping voltage, and Low capacitance (10pF) no device degradation. Solid-state silicon-avalanche technology TM The Clamp 0508T is in a 8-pin, RoHS/WEEE compli- ant, SLP1713P8T package. It measures 1.7 x 1.3 mm Mechanical Characteristics with a nominal height of only 0.4mm. The leads are SLP1713P8T package spaced at a pitch of 0.4mm and are finished with lead- RoHS/WEEE Compliant free NiPdAu. Each device features eight TVS diodes Nominal Dimensions: 1.7 x 1.3 x 0.4 mm with an operating voltage of 5 volts and a maximum Lead Finish: NiPdAu loading capacitance of only 10pF. Molding compound flammability rating: UL 94V-0 They may be used to meet the ESD immunity require- Marking : Marking code ments of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge). The combination of small size and Packaging : Tape and Reel high ESD surge capability makes them ideal for use in Applications portable applications such as cellular phones, digital cameras, and notebook computers.
