uClamp0554T Ultra Small Clamp 4-Line ESD Protection PROTECTION PRODUCTS PROTECTION PRODUCTS - MicroClamp Features Description Clamp TVS diodes are designed to protect sensitive High ESD withstand Voltage: +/-15kV (Contact) per electronics from damage or latch-up due to ESD. They IEC 61000-4-2 2 are designed to replace multilayer varistors (MLVs) in por- Very small PCB area: 0.8mm table applications such as cell phones, notebook com- Protects up to four data lines puters, and other portable electronics. They feature large Low reverse current: <3nA typical (VR=5V) cross-sectional area junctions for conducting high tran- Working voltage: +/- 5V sient currents. This device offers desirable characteris- Low capacitance: <7pF (VR=0V) tics for board level protection including fast response Low dynamic resistance: 0.70 Ohms (Typ) time, low operating and clamping voltage, and no device Solid-state silicon-avalanche technology degradation. The Clamp 0554T is in a 4-pin SLP0808P4T package. Mechanical Characteristics It measures 0.8 x 0.8 mm with a nominal height of only SLP0808P4T package 0.3mm. The leads are finished with lead-free NiPdAu. Pb-Free, Halogen Free, RoHS/WEEE Compliant Each device will protect four lines operating at 5 volts. Nominal Dimensions: 0.8 x 0.8 x 0.30 mm It gives the designer the flexibility to replace multiple Lead Pitch: 0.48mm single line devices in space constrained applications. Lead Finish: NiPdAu They may be used to meet the ESD immunity require- ments of IEC 61000-4-2. The combination of small Molding compound flammability rating: UL 94V-0 size and high ESD surge capability makes them ideal Marking : Marking code + dot matrix date code for use in portable applications such as cellular Packaging : Tape and Reel phones, digital cameras, and tablet computers.
