uClamp3301H TM Low Voltage Clamp for ESD and CDE Protection PROTECTION PRODUCTS PRELIMINARY PROTECTION PRODUCTS -MicroClamp Features Description The Clamp series of Transient Voltage Suppressors Transient protection for data lines to (TVS) are designed to replace multilayer varistors IEC 61000-4-2 (ESD) 30kV (air), 30kV (contact) (MLVs) in portable applications such as cell phones, IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) notebook computers, and PDAs. They offer superior Cable Discharge Event (CDE) electrical characteristics such as lower clamping Small SOD-523 package voltage and no device degradation when compared to Protects one data line MLVs. They are designed to protect sensitive semicon- Low clamping voltage ductor components from damage or upset due to Working voltage: 3.3V electrostatic discharge (ESD), lightning, electrical fast Low leakage current transients (EFT), and cable discharge events (CDE). Solid-state silicon-avalanche technology The Clamp 3301H is constructed using Semtechs proprietary EPD process technology. The EPD process Mechanical Characteristics provides low standoff voltages with significant reduc- EIAJ SOD-523 package tions in leakage currents and capacitance over silicon- Pb-Free, Halogen Free, RoHS/WEEE Compliant avalanche diode processes. They feature a true Molding compound flammability rating: UL 94V-0 operating voltage of 3.3 volts for superior protection Nominal Dimensions: 1.7 x 0.9 x 0.7mm when compared to traditional pn junction devices. Marking : Marking code, cathode band The Clamp3301H is in a 2-pin SOD-523 package. Packaging: Tape and Reel Each device will protect one unidirectional line operat- Lead Finish: Matte tin ing at 3.3 volts. They give the designer the flexibility to protect one line in applications where arrays are not Applications practical. They may be used to meet the ESD immunity Cellular Handsets & Accessories requirements of IEC 61000-4-2.
