RClamp0551P Ultra-Low Capacitance 1-Line, 5V ESD protection PROTECTION PRODUCTS - RailClamp® Description PRELIMINARY Features Transient protection for data lines to RailClamp® TVS arrays are ultra low capacitance ESD protection devices designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). RClamp®0551P has a maximum capacitance of 0.50pF. This allows it to be used on circuits operating in excess of 5GHz without appreciable signal attenuation. They exceed the ESD immunity requirements of IEC 61000-4-2, Level 4. IEC 61000-4-2 (ESD) ±17kV (air), ±17kV (contact) IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) Cable Discharge Event (CDE) Ultra-small package (1.0 x 0.6 x 0.5mm) Protects one data or I/O line Low capacitance: 0.50pF Dynamic Resistance: 1.3 Ohms Typical Low ESD clamping voltage Operating voltage: 5V Solid-state silicon-avalanche technology Mechanical Characteristics RClamp0551P is in a 2-pin SLP1006P2 package measuring 1.0 x 0.6 x 0.5mm. Leads are spaced at a pitch of 0.65mm and feature a lead-free finish. Each device will protect one high-speed line operating at 5 volts. It gives the designer the flexibility to protect single lines in applications where arrays are not practical. The combination of small size, low capacitance, and high ESD surge capability makes them ideal for use in applications such as cellular phones and digital video interfaces.

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: 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. Never run critical signals near board edges. Use ground planes whenever possible. © 2015 Semtech Corporation 4 www.semtech.com RClamp0551P PRELIMINARY PROTECTION PRODUCTS Outline OutlineDrawing Drawing- -SO-8 SLP1006P2 A B D DIMENSIONS INCHES MILLIMETERS DIM MIN NOM MAX MIN NOM MAX E TOP VIEW A SEATING PLANE aaa C C A1 A A1 b D E e L R N aaa bbb .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.
