uClamp3301D

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 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).

100 Watts peak pulse power (tp = 8/20µs)

Transient protection for data lines to

IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)

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

IEC 61000-4-5 (Lightning) 10A (tp = 8/20µs)

Small package for use in portable electronics

Suitable replacement for MLVs in ESD protection

applications

Protects one line

Low clamping voltage

Working voltages: 3.3V

Low leakage current

The µClamp^TM3301D 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.

Solid-state silicon-avalanche technology

Mechanical Characteristics

EIAJ SOD-323 package

Molding compound flammability rating: UL 94V-0

Marking: Marking code, cathode band

Packaging: Tape and Reel

The µClamp3301D 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.

Lead Finish: Matte tin

RoHS/WEEE Compliant

They may be used to meet the ESD immunity require-

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

contact discharge).

Applications

Cell Phone Handsets and Accessories

Laser Diode Protection

Notebooks, Desktops, & Servers

Portable Instrumentation
