DESCRIPTION
APPEARANCE
This TRANSIENT VOLTAGE SUPPRESSOR (TVS) array is packaged in an SO-8
configuration giving protection to 4 unidirectional or bi-directional data or interface
lines. It 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 61000-4-2, electrical fast transients (EFT) per IEC 61000-4-4 and effects of
secondary lightning. These TVS arrays have peak pulse power ratings of 300 watts
(SMDA) and 500 watts (SMDB) for an 8/20 sec pulse. They are suitable for
protection of sensitive circuitry consisting of TTL, CMOS, DRAM’s, SRAM’s,
HCMOS, HSIC and low-voltage interfaces from 3.3 volts to 24 volts
IMPORTANT:
For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

Note: Transient Voltage Suppressor (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. Part numbers with a C suffix are bi-directional devices.
* Device marking has an e3 suffix added for the RoHS Compliant options, e.g. SDKe3, SDLe3, SDCe3, SDEe3, PDHe3, etc.
