TVSarray
 Series
DESCRIPTION (500 watt)
This TRANSIENT VOLTAGE SUPPRESSOR (TVS) array is packaged
in an SO-8 configuration giving protection to 2 Unidirectional 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 1000-4-2, electrical
fast transients (EFT) per IEC 1000-4-4 and effects of secondary
lighting.
These TVS arrays have a peak power rating of 500 watts for an
8/20µsec 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 USB08XX product provides board level protection from static electricity and other induced voltage
surges that can damage or upset sensitive circuitry.

NOTE: TVS product is normally selected based on its stand off Voltage VWM. Product selected voltage should be
equal to or greater than the continuous peak operating voltage of the circuit to be protected.
Application: The USB08XX product is designed for transient voltage suppression protection of ESD sensitive
components at the board level. It is an ideal product to be used for protection of I/O Transceivers.
