uClamp0544P TM Clamp 4-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 single line devices such IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) as multilayer varistors (MLVs) in space constrained ap- Cable Discharge Event (CDE) plications such as cell phones, notebook computers, and Ultra-small package other portable electronics. It features large cross-sec- Protects four data lines tional area junctions for conducting high transient cur- Low clamping voltage rents. TVS diodes offer desirable characteristics for Working voltage: 5V board level protection including fast response time, low Low capacitance (10pF) operating and clamping voltage, and no device degrada- Solid-state silicon-avalanche technology tion.

The leads are spaced at RoHS/WEEE Compliant a pitch of 0.5mm and are finished with lead-free Nominal Dimensions: 2.5 x 1.0 x 0.58 mm NiPdAu. They are designed for easy PCB layout by Lead Finish: NiPdAu allowing the traces to run straight through the device. Each device features four TVS diodes with an operat- Molding compound flammability rating: UL 94V-0 ing voltage of 5 volts and a maximum loading capaci- Marking : Marking code tance of only 10pF.
