SMS3.3

3.3 Volt TVS Array

For ESD and Latch-Up Protection

PROTECTION PRODUCTS

Features

Description

Transient protection for data lines to

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

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

IEC 61000-4-5 (Lightning) 12A (8/20µs)

Protects four I/O lines

The SMS series of TVS arrays are designed to protect

sensitive electronics from damage or latch-up due to

ESD, lightning, and other voltage-induced transient

events. Each device will protect up to four lines operating

at 3.3 volts.

Working voltage: 3.3V

Low leakage current (<1µA)

Low clamping voltage

Low capacitance (35pF typical)

Solid-state EPD TVS technology

The SMS3.3 is a solid-state device designed specifically

for transient suppression. It 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

traditional pn junction processes. They offer desirable

characteristics for board level protection including fast

response time, low clamping voltage and no device

degradation.

Mechanical Characteristics

EIAJ SOT23-6L package

Molding compound flammability rating: UL 94V-0

Marking : Marking Code

Packaging : Tape and Reel per EIA 481

The SMS3.3 may be used to meet the immunity require-

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

contact discharge). The low cost SOT23-6L package

makes them ideal for use in portable electronics such

as cell phones, PDA’s, and notebook computers.

Applications

Cell phone Handsets and Accessories

Microprocessor Based Equipment

Personal Digital Assistants (PDA’s) and Pagers

Desktops PC and Servers

Notebook, Laptop, and Palmtop Computers

Portable Instrumentation

Peripherals

MP3 Players

Cordless Phones
