Bidirectional TVSarray
PRODUCT PREVIEW
SCOTTSDALE DIVISION
DESCRIPTION
This TRANSIENT VOLTAGE SUPPRESSOR (TVS) array is packaged in an SO-8
configuration giving protection to 2 Bidirectional data or interface lines. It is designed
for use in applications where protection is required at the board level from voltage
transients caused by electrostatic discharge (ESD) as defined in IEC 61000-4-2,
electrical fast transients (EFT) per IEC 61000-4-4 and effects of secondary lightning.
These TVS arrays have a peak power rating of 500 watts for an 8/20
μ
sec pulse.
This array is suitable for protection of sensitive circuitry consisting of TTL, CMOS
DRAM’s, SRAM’s, HCMOS, HSIC microprocessors,
UNIVERSAL SERIAL BUS
(USB)
and I/O transceivers. The USB08XXC product provides board level protection
from static electricity and other induced voltage surges that can damage or upset
sensitive circuitry.
