DESCRIPTION (500 watt)

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 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

8/20

µsec pulse. This array is suitable for protection of sensitive circuitry consisting of TTL, CMOS

DRAM’s, SRAM’s, HCMOS, HSIC microprocessors, and I/O transceivers. The SM8LCXX product provides

board level protection from static electricity and other induced voltage surges that can damage sensitive

circuitry.
