Unidirectional Low Capacitance TVSarray ™

DESCRIPTION  
APPEARANCE  
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 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 7 & 8 are tied together for the first  
protected positive line, and pins 1 & 2 are tied together to the ground. The same  
would then occur where pins 5 & 6 are tied together for a second protected positive  
line and pins 2 & 3 are tied together to the ground. If protecting a negative line with  
respect to ground, these may be switched in polarity connections where the pins are  
tied together in this manner for Unidirectional 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 USB508XX product provides board level protection  
from static electricity and other induced voltage surges that can damage or upset  
sensitive circuitry.
