SMF3.3

3.3 Volt TVS Array

For ESD and Latch-Up Protection

PROTECTION PRODUCTS

Features

Description

The SMF 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 operat-

ing at 3.3 volts.

! ESD protection for data lines to

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

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

! Small package for use in portable electronics

! Protects four I/O lines

! Working voltage: 3.3V

! Low leakage current

! Low operating and clamping voltages

! Solid-state EPD TVS technology

The SMF3.3 is a solid-state devices designed specifi-

cally 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 capaci-

tance 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 SC70-5L package

! Molding compound flammability rating: UL 94V-0

! Marking : Marking Code

! Packaging : Tape and Reel per EIA 481

The SMF3.3 may be used to meet the immunity re-

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

contact discharge). The small SC70-5L package

makes them ideal for use in portable electronics such

as cell phones, PDAs, and notebook computers.

Applications

! Cellular Handsets and Accessories

! Cordless Phones

! Personal Digital Assistants (PDAs)

! Notebooks and Handhelds

! Portable Instrumentation

! Digital Cameras

! Peripherals

! MP3 Players
