DESCRIPTION APPEARANCE
This 16 pin 8-line Low Capacitan ce Unidirectional array is designed for use
in applications where protection is required at the board level from voltage
transients cause d 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 500 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.
SO-16
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

NOTE: Transient Voltage Suppression (TVS) product is normally selected based on its standoff 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 SM16LCXX product is designed for unidirectional transient voltage suppression protection of components at the board level. It is an
ideal product to be used for protection of I/O Transceivers. See separate data sheet for bidirectional TVS in the SM16LCXXC series (with C suffix).
