Description
The SMDAXX-6 series of TVS array have been
designed to provide unidirectional protection for
sensitive electronics from damage due to voltage
transients caused by electrostatic discharge
(ESD), electrical fast transients (EFT), lightning
and other voltage-induced transient events. The
device can be used to protect combinations of
six unidirectional lines.

Circuit Diagram
The SMDAxx-6 is designed to protect up to 6 data or
I/O lines operating at 5 volts. They are unidirectional
devices and may be used on lines where the signal
polarities are above ground (i.e. 0 to 5V).
The devices are connected as follows:
Pins 1, 2, 3, 4, 5 and 8 are connected to the lines
that are to be protected. Pins 6 and 7 are connected
to ground. The ground connections should be made
directly to the ground plane for best results. The
path length is kept as short as possible to reduce
the effects of parasitic inductance in the board
traces.
