Bidirectional TVSarray ™

S C O T TS DALE DIVISION

USB0803C-A thru USB0824C-A, e3

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. It is

also available with either Tin-Lead plated terminations or as RoHS Compliant with

annealed matte-Tin finish by adding an “e3” suffix to the part number*.

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.

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-A product provides board level protection from static

electricity and other induced voltage surges that can damage or upset sensitive circuitry.
