UCLAMP3311P Datasheet PDF - Semtech Corporation

The µClamp series low voltage TVS Diode for ESD and CDE protection. It is designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers and PDAs. It offers superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs. The device is designed to protect sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD), lightning, electrical fast transients (EFT) and cable discharge events (CDE). The device is constructed using Semtech"s proprietary EPD process technology. The EPD process provides low standoff voltages with significant reductions in leakage currents and capacitance over silicon avalanche diode processes. It features a true operating voltage of 3.3V for superior protection when compared to traditional PN junction devices. It gives the designer the flexibility to protect one line in applications where arrays are not practical.
