描述 Description

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. 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.
