Unidirectional TVS Array

for Protection of Four Lines

PROTECTION PRODUCTS

Features

Description

The SMDAxx series of TVS arrays are designed to provide

undirectional protection for sensitive electronics from

damage or latch-up due to ESD, lightning and other

voltage-induced transient events. Each device will

protect four data or I/O lines. They are available with

operating voltages of 5V, 12V, 15V and 24V.

u 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)

u Undirectional protection

u Small SO-8 package

u Protects four I/O lines

u Working voltages: 5V, 12V, 15V and 24V

u Low leakage current

u Low operating and clamping voltages

u Solid-state silicon avalanche technology

TVS diodes are solid-state devices designed specifically

for transient suppression. They offer desirable charac-

teristics for board level protection including fast re-

sponse time, low operating and clamping voltage and no

device degradation. The low profile SO-8 package allows

the user to protect up to four independent lines with one

package. The SMDAxx series is suitable protection for

sensitive semiconductors components such as micropro-

cessors, ASICs, transceivers, transducers, and CMOS

memory.

Mechanical Characteristics

u JEDEC SO-8 package

u Molding compound flammability rating: UL 94V-0

u Marking : Part number, date code, logo

u Packaging : Tube or Tape and Reel per EIA 481

The SMDAxx series devices may be used to meet the

ESD immunity requirements of IEC 61000-4-2, level 4 for

air and contact discharge.

Applications

u RS-232 data lines

u Microprocessor based equipment

u Notebooks, Desktops, & Servers

u Instrumentation

u LAN/WAN equipment

u Peripherals

u Serial and Parallel Ports
