DESCRIPTION
APPEARANCE
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 very low capacitance 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.
Using the schematic on the second page, pins 1 & 2 are tied together for the first
protected line, and pins 7 & 8 are tied together to the ground. The same would then
occur for a second protected line where pins 3 & 4 are tied together and pins 5 & 6 are
tied together to the ground. These may also be switched in polarity connections since
the electrical features are the same in each antiparallel (opposite facing) leg when the
pins are tied together in this manner for bidirectional protection.
SO–8
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 USB508XXC product provides board level protection
from static electricity and other induced voltage surges that can damage or upset
sensitive circuitry.

Transient Voltage Suppressor (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.
