PRODUCT PREVIEW
DESCRIPTION
TVS array™ SERIES
Microsemi’s proprietary Zener process provides low standoff voltages and the
lowest standby current in the industry of 0.1µA. This 4 pin unidirectional 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.
This product is designed to provide protection in the unidectional mode for 1 line
by connecting the Input/Output line to pin 2 and 3 and pin 1 and 4 to ground. The
SLVG2.8K product provides board level protection from static electricity and other
induced-voltage surges that can damage sensitive circuitry.
APPLICATIONS
· EIA-RS232 data rates
These Transient Voltage Suppressor (TVS) diode arrays protect 2.8 V low
voltage components such as DRAM’s SRAM’s CMOS, HCMOS, HSIC, and low
voltage interfaces. Because of the physical size, weight and protection capabilities,
this product is ideal for use in but not limited to miniaturize electronic equipment
such as hand held instruments, computers, computer peripherals and cell phones.
