Unidirectional TVS Array
for Protection of Six Lines
PROTECTION PRODUCTS
Description
The SMDA series of transient voltage suppressors are
designed to protect components which are connected
to data and transmission lines from voltage surges
caused by electrostatic discharge (ESD), electrical fast
transients (EFT), and lightning.
TVS diodes are characterized by their high surge
capability, low operating and clamping voltages, and
fast response time. This makes them ideal for use as
board level protection of sensitive semiconductor
components. The SMDA05-6 is designed to provide
transient suppression on multiple data lines and I/O
ports. It is designed to operate on 5V digital lines. The
low profile SO-8 design allows the user to protect up to
six data and I/O lines with one package.
The SMDA05-6 TVS diode array will meet the surge
requirements of IEC 61000-4-2 (Formerly IEC 801-2),
Level 4, “Human Body Model” for air and contact
discharge.
