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. 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.
