Description
Features
®
u Transient protection for data lines to
The RClamp 3321P provides ESD protection for USB3.0,
HDMI1.3/1.4, and other high-speed ports. It may be
used to meet the ESD immunity requirements of IEC
61000-4-2. The RClamp3321P is designed to minimize
both the ESD peak clamping and the TLP clamping. The
dynamic resistance is minimized (0.47 Ohms typical) for
optimum protection of sensitive circuits. Maximum capacitance is only 0.35pF. This allows the RClamp3321P
to be used in applications operating in excess of 5GHz
without signal attenuation. These devices are manufactured using Semtech’s proprietary low voltage technology for superior characteritics at operating voltages up
to 3.3 volts.
The RClamp3321P is in a 2-pin SLP1006P2 package. It
measures 1.0 x 0.6 x 0.5mm. The leads are spaced at a
pitch of 0.65mm and are finished with lead-free NiPdAu.
Each device will protect one line operating at 3.3 volts.
The combination of low peak ESD clamping, low dynamic
resistance, and low capacitance makes this device suitable for applications such as USB 3.0, HDMI and V-ByOne interfaces in portable devices.

These low capacitance TVS diodes are designed to
provide common mode protection for one high-speed
line or differential protection for one line pair. The
device is bidirectional and may be used on lines where
the signal polarity is positive and negative.

Circuit Board Layout Recommendations for Suppression of ESD.
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:
l Place the TVS near the input terminals or connectors
to restrict transient coupling.
l Minimize the path length between the TVS and the
protected line.
l Minimize all conductive loops including power and
ground loops.
l The ESD transient return path to ground should be
kept as short as possible.
l Never run critical signals near board edges.
l Use ground planes whenever possible.
