SMDB03 THRU SMDB36 TVS ARRAY SERIES
Description
The SMDBXX 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 SMDBxx series of devices are designed to protect up to four
data lines. The devices are connected as follows:
✔
The SMDBxx 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.
