DESCRIPTION (300 watt)
This 16 pin 8 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 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.

Part numbers with a “C” suffix are bidirectional devices
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 SM16XX/XXC 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.
