The UCLAMP3301D.TCT is a 2-pin Transient Voltage Suppressor designed to replace multilayer varistors (MLVs) in portable applications. It offers superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs. It 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 µClamp™ 3301D is constructed using Semtechs 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 array is not practical.
