Description

The μClamp? series of Transient Voltage Suppressors (TVS) are designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDAs. They offer superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs. They are 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?3301H 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. They feature a true operating voltage of 3.3 volts for superior protection when compared to traditional pn junction devices.

The μClamp3301H is in a 2-pin SOD-523 package. Each device will protect one unidirectional line operating at 3.3 volts. They give the designer the flexibility to protect one line in applications where arrays are not practical. They may be used to meet the ESD immunity requirements of IEC 61000-4-2.
