SMS03C thru SMS24C

4 LINE BIDIRECTIONAL TVSarray ™

PRODUCT PREVIEW

SCOTTSDALE DIVISION

DESCRIPTION

This 6 pin 4 line bi-directional array is designed for use in applications where

protection is required at the board level from voltage transients caused by

electrostatic discharge (ESD) as defined by IEC 61000-4-2, electrical fast

transients (EFT) per IEC 61000-4-4 and effects of secondary lighting.

These arrays are used to protect 4 discrete lines utilizing pins (1,3,4,6) with a

common (pin 5) configuration.

The SMS03C thru SMS24C product provides

board level protection from static electricity and other induced voltage surges that

can damage sensitive circuitry.

These Transient Voltage Suppressor (TVS) diode arrays protect 3.0/3.3 volt

components such as DRAM’s SRAM’s CMOS, HCMOS, HSIC, and low voltage

interfaces up to 24 volts.

Because of the physical size, weight and protection

capabilities, this product is ideal for use in but not limited to miniaturized

electronic equipment such as hand held instruments, computers, computer

peripherals and cell phones.
