PRODUCT PREVIEW
DESCRIPTION
TVS array™ SERIES
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.
APPLICATIONS
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.
