DESCRIPTION (300 watt)
This 14 pin 8 line Bi-directional 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
in IEC 1000-4-2, electrical fast transients (EFT) per IEC 1000-4-4 and
effects of secondary lighting.
These TRANSIENT VOLTAGE SUPPRESSOR (TVS) Diode Arrays
have a peak power of 300 watts for an 8/20 µsec pulse and are designed to protect 3.0/3.3 volt
components such as DRAM’s, SRAM’s, CMOS, HCMOS, HSIC, and low voltage interfaces up to 24 volts.

NOTE: Transient Voltage Suppression (TVS) product is normally selected based on its stand off voltage
VWM. Product selected voltage should be equal to or greater than the continuous peak operating voltage of
the circuit to be protected.
Application: The SMDAXXC-8 product is designed for transient voltage suppression protection of
components at the board level. It is an ideal product to be used for protection of I/O Transceivers.
