The μClamp

(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 semicon-

ductor components from damage or upset due to

electrostatic discharge (ESD), lightning, electrical fast

transients (EFT), and cable discharge events (CDE).

The μClamp

proprietary EPD process technology. The EPD process

provides low standoff voltages with significant reduc-

tions 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 SOD-523 package and will

protect one unidirectional line. 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 require-

ments of IEC 61000-4-2, Level 4 (±15kV air, ±8kV

contact discharge).
