TVSarrayÔ 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  
8/20msec 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.

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 USB508XX 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.
