RClamp3321P Ultra-Low Capacitance 1-Line, 3.3V ESD protection PROTECTION PRODUCTS - RailClamp 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.

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. 2013 Semtech Corporation. & ))&( <)< 6 www.semtech.com RClamp3321P PROTECTION PRODUCTS Outline Drawing - SLP1006P2 A B D DIMENSIONS INCHES MILLIMETERS DIM MIN NOM MAX MIN NOM MAX E A A1 b D E e L R N aaa bbb TOP VIEW A SEATING PLANE aaa C C A1 .016 .020 .022 .000 .001 .002 .018 .020 .022 .035 .039 .043 .020 .024 .028 .026 BSC .008 .010 .012 .002 .004 .006 2 .003 .004 0.40 0.50 0.55 0.00 0.03 0.05 0.45 0.50 0.55 0.90 1.00 1.10 0.50 0.60 0.70 0.65 BSC 0.20 0.25 0.30 0.05 0.10 0.15 2 0.08 0.10 PIN 1 ID R bxN bbb C A B 2x L e BOTTOM VIEW NOTES: 1.
