RoHS Compliant Product
Trans ient Voltage Suppressors
DESCRIPTION (300 and 500 watt)
This 8 pin 4 line Unidirectional or Bidirectional array is designed for use in
applications where protection is required at the board level 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 lighting.
These arrays are used to protect any combination of 4 lines. The SMDA/B 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 3.0/3.3
Volt components such as DRAM’s, SRAM’s, CMOS, HCMOS, HSIC, and low
voltage interfaces up to 24Volts.

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.
