| 8700 E. Thomas Road Scottsdale, AZ 85252 Tel: (480) 941-6300 Fax: (480) 947-1503 USB0803 thru USB0824 TVSarrayTM Series TM 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 8/20sec 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 USB08XX product provides board level protection from static electricity and other induced voltage surges that can damage or upset sensitive circuitry.

Product selected voltage should be equal to or greater than the continuous peak operating voltage of the circuit to be protected. Application: The USB08XX 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.
