Bidirectional TVSarray ™

PRODUCT PREVIEW

SCO TTSD A L E DI VI SI ON

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

µsec 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.
