• Description: IC,EMI Filter,FP,6PIN,PLASTIC
• Manufacturer: Semtech

Specifications of ECLAMP3202A.TCT

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

Device Connection Options
The EClamp3202A provides EMI filtering and ESD
protection in a small SC-89 package for speaker port
applications. The equivalent circuit diagram is shown
below. The layout of the device is designed such that
the data lines can be routed through the device. The
first line pair enters at pins 1 and exits at pins 6. The
second line pair enters at pins 3 and exits at pins 4.
The device is symmetrical so the above connections
may be reversed. Layout examples are shown to the
right.
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:

Applications Information
2006 Semtech Corp.
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.
