DESCRIPTION (300 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.
These arrays are used to protect 1 discrete line utilizing pins (1,4 and
2,3).  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

NOTE:
 Transient Voltage Suppression (TVS) product is normally selected based on its stand off Voltage
V
WM
.  Product selected voltage should be equal to or greater than the continuous peak operating voltage of
the circuit to be protected.
