Device Connection for Protection of Seven Data Lines
The SMDAxxC-7 is designed to protect up to 7 data or
I/O lines. They are bidirectional devices and may be
used on lines where the signal polarities are above and
below ground.
The SMDAxxC-7 TVS arrays employ a monolithic struc-
ture. Therefore, the working voltage (V
RWM) and break-
down voltage (V
BR) specifications apply to the differen-
tial voltage between any two data line pins. For ex-
ample, the SMDA24C-7 is designed for a maximum
voltage excursion of ±12V between any two data lines.
The device is connected as follows:
Pins 1, 2, 3, 4, 5, 6 and 7 are connected to the
lines that are to be protected. Pin 8 is 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.
Circuit Board Layout Recommendations for Suppres-
sion of ESD.
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:
Place the TVS near the input terminals or connec-
tors to restrict transient coupling.
Minimize the path length between the TVS and the
protected line.
Minimize all conductive loops including power and
ground loops.
The ESD transient return path to ground should be
kept as short as possible.
Never run critical signals near board edges.
Use ground planes whenever possible.
