Device Connection for Protection of Six Data Lines
The SMDA05-6 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 device is 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 con-
nected to ground. The ground connections should
be made directly to the ground plane for best
results. The path length is kept as short as pos-
sible 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.
Matte Tin Lead Finish
Matte tin has become the industry standard lead-free
replacement for SnPb lead finishes. A matte tin finish
is composed of 100% tin solder with large grains.
Since the solder volume on the leads is small com-
pared to the solder paste volume that is placed on the
land pattern of the PCB, the reflow profile will be
determined by the requirements of the solder paste.
Therefore, these devices are compatible with both
lead-free and SnPb assembly techniques. In addition,
unlike other lead-free compositions, matte tin does not
have any added alloys that can cause degradation of
the solder joint.
