SMS03C thru SMS24C
4 LINE BIDIRECTIONAL TVSarray ™
SCOTTSDALE DIVISION
PRODUCT PREVIEW
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. B
ecause 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.

DEFINITION
Rated stand off voltage: Maximum dc voltage that can be applied over the operating temperature range. Vwm
must be selected to be equal or be greater than the operating voltage of the line to be protected
Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current
Clamping Voltage: Maximum clamping voltage across the TVS device when subjected to a given current at a
pulse time of 20
µs.
Standby Current: Leakage current at V
WM.
Capacitance: Capacitance of the TVS as defined @ 0 volts at a frequency of 1 MHz and stated in Pico Farads.
