RClamp3321P  
Ultra-Low Capacitance  
1-Line, 3.3V ESD protection  
PROTECTION PRODUCTS - RailClamp  
Description  
Features  
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 ca-  
pacitance is only 0.35pF. This allows the RClamp3321P  
to be used in applications operating in excess of 5GHz  
without signal attenuation. These devices are manufac-  
tured using Semtech’s proprietary low voltage technol-  
ogy 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 suit-  
able for applications such as USB 3.0, HDMI and V-By-  
One interfaces in portable devices.

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 connectors  
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.  
&
w/ꢀꢁꢂꢃ))&(t<)<wꢄ  
ꢁ
ꢁ
Never run critical signals near board edges.  
Use ground planes whenever possible.
