DESCRIPTION (500 watt)

This 4 pin 1 line unidirectional ULTRA LOW CAPACITANCE array is

designed for use in applications requiring board level protection from

voltage transients caused by electrostatic discharge (ESD) as defined

by IEC 1000-4-2, electrical fast transients (EFT) per IEC 1000-4-4 and

effects of secondary lightning.

These arrays are used to protect 1 discrete line utilizing pins (1,4 signal

and 2,3 ground). The S0T-143 product provides board level protection

from static electricity and other induced voltage surges that can

damage sensitive circuitry.

These TRANSIENT VOLTAGE SUPPRESSOR (TVS) Diode Arrays protect 3.3 Volt components such as

DRAM’s, SRAM’s, CMOS, HCMOS, HSIC, and low voltage interfaces up to 24Volts.
