DESCRIPTION (500 watt)
This 4 pin 1 line bidirectional 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.
TVSarray ™ Series
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.
FEATURES
Protects 3.3 up through 24V Components
Protects 1 line bidirectional
Provides electrically isolated protection
