3.3 Volt TVS Array For ESD and Latch-Up Protection 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 operating at 3.3 volts. The SMF3.3 is a solid-state devices designed specifically for transient suppression. It is 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. The SMF3.3 may be used to meet the immunity requirements 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, PDA’s, and notebook computers.

For ESD and Latch-Up Protection

PRELIMINARY

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)

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 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

Applications

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, PDA’s, and notebook computers.
