Low Voltage µClamp^TM

for ESD and CDE Protection

PROTECTION PRODUCTS - MicroClamp^TM

Features

Description

The µClamp^TMseries 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 semicon-

ductor components from damage or upset due to

electrostatic discharge (ESD), lightning, electrical fast

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

Transient protection for data lines to

IEC 61000-4-2 (ESD) 20kV (air), 10kV (contact)

IEC 61000-4-4 (EFT) 40A (tp = 5/50ns)

Cable Discharge Event (CDE)

Ultra-small SOD-523 package (1.7 x 0.9 x 0.7mm)

Protects one I/O or power line

Low clamping voltage

Working voltage: 3.3V

Low leakage current

Solid-state silicon-avalanche technology

The µclamp^TM3301H is constructed using Semtech’s

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.

Mechanical Characteristics

EIAJ SOD-523 package

Molding compound flammability rating: UL 94V-0

Marking : Marking code, cathode band

Packaging : Tape and Reel per EIA 481

Lead Finish: Matte tin

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.

Applications

Cellular Handsets & Accessories

Cordless Phones

Personal Digital Assistants (PDAs)

Notebooks & Handhelds

Portable Instrumentation

Digital Cameras

They may be used to meet the ESD immunity require-

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

contact discharge).

Peripherals

MP3 Players
