TVSarray Series
DESCRIPTION (500 watt)
This TRANSIENT VOLTAGE SUPPRESSOR (TVS) array is packaged
in a SO-8 configuration giving protection to one pair of Bidirectional
data lines and the Vbus. 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 designed for protection of sensitive
circuitry consisting of UNIVERSAL SERIAL BUS (USB) I/O transceivers.
The capacitance between the I/O data lines are minimal too ensure no significant signal distortion or loss at
the 12 Megabit or greater data rate. This feature allows full compatibility with USB port standards.
