UCLAMP3301D

Description

The Clamp^TMseries of Transient Voltage Suppressors

(TVS) are designed to replace multilayer varistors

(MLVs) in portable applications such as cell phones, no-

tebook computers, and PDAs. They offer superior

electrical characteristics such as lower clamping

voltage and no device degradation when compared to

MLVs. They are 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 UClamp3301D is constructed using proprietary

EPD process technology.

The EPD process provides low standoff voltages with

significant reduc-tions in leakage currents and capaci-

tance over silicon-avalanche diode processes. They fe-

ature a true operating voltage of 3.3 volts for superior

protection when compared to traditional pn junction

devices.

The UClamp3301D is in a SOD-323 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).
