SMDA03 THRU SMDA36 TVS ARRAY SERIES
Description
The SMDAXX 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
four unidirectional lines.

Circuit Diagram
The SMDAxx series of devices are designed to protect up to four data
lines. The devices are connected as follows:
✔
The SMDAxx are unidirectional devices and are designed for use on
line where the normal operating voltage is above ground. Pins 1, 2,
3, and 4 are connected to the protected lines. Pins 5, 6, 7, and 8
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.
