uClamp3301P Low Voltage Clamp for ESD and CDE Protection PROTECTION PRODUCTS PROTECTION PRODUCTS - MicroClamp Features Description The Clamp TVS diodes are designed to replace Transient protection for data lines to multilayer varistors (MLVs) in portable applications such IEC 61000-4-2 (ESD) as cell phones, notebook computers, and PDAs. They IEC 61000-4-4 (EFT) offer superior electrical characteristics such as lower Cable Discharge Event (CDE) clamping voltage and no device degradation when Ultra-small package compared to MLVs. They are designed to protect Protects one data line sensitive semiconductor components from damage or Low clamping voltage upset due to electrostatic discharge (ESD), lightning, Working voltage: 3.3V electrical fast transients (EFT), and cable discharge Low leakage current events (CDE). Solid-state silicon-avalanche technology The Clamp 3301P is constructed using Semtechs Mechanical Characteristics proprietary EPD process technology. The EPD process provides low standoff voltages with significant reduc- SLP1006P2 package tions in leakage currents and capacitance over silicon- Pb-Free, Halogen Free, RoHS/WEEE Compliant avalanche diode processes. They feature a true Nominal Dimensions: 1.0 x 0.6 x 0.5 mm operating voltage of 3.3 volts for superior protection Lead Finish: NiPdAu when compared to traditional pn junction devices. Molding compound flammability rating: UL 94V-0 The Clamp3301P is in an 2-pin SLP1006P2 package. Marking: Marking code, cathode band It measures 1.0 x 0.6 x 0.5mm. The leads are spaced Packaging: Tape and Reel at a pitch of 0.65mm and are finished with lead-free NiPdAu. Each device will protect one line operating at Applications 3.3 volts. It gives the designer the flexibility to protect Cellular Handsets & Accessories single lines in applications where arrays are not practi- Personal Digital Assistants (PDAs) cal. They may be used to meet the ESD immunity Notebooks & Handhelds requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge). The combination of small Portable Instrumentation size and high ESD surge capability makes them ideal Digital Cameras for use in portable applications such as cellular Peripherals phones, digital cameras, and MP3 players.
