SMDB03C THRU SMDB24C TVS ARRAY SERIES
Description
The SMDBXXC series of TVS array have been
designed to provide bidirectional 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
Bidirectional lines.

Circuit Diagram
The SMDBxxC series of devices are designed to protect up to
four data lines. The devices are connected as follows:
✔
The SMDBxxC are bidirectional 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. Since the
device is electrically symmetrical, these connections may be
reversed. 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.
