RClamp0521P Ultra-Low Capacitance 1-Line ESD protection PROTECTION PRODUCTS - RailClamp Description PRELIMINARY Features 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). u Transient protection for data lines to u u u u u u The RClamp0521P has a maximum capacitance of only 0.50pF. This allows it to be used on circuits operating in excess of 3GHz without signal attenuation. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (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: 0.5pF Low clamping voltage Low operating voltage: 5.0V Solid-state silicon-avalanche technology Mechanical Characteristics u u u u u u The RClamp0521P is in a 2-pin SLP1006P2 package measuring 1.0 x 0.6 x 0.5mm. The 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: 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. 2012 Semtech Corporation 4 www.semtech.com RClamp0521P PRELIMINARY PROTECTION PRODUCTS Applications Information - Spice Model I/O Line RClamp0521P Spice Model R Clamp0521P Spice Parameters 2012 Semtech Corporation Parameter Unit D1 (LCR D) D2 (LCR D) D3 (T VS) IS A mp 1.0E-20 1.0E-20 2.0E-12 BV Volt 100 100 9.36 VJ Volt 0.7 0.7 0.6 RS Ohm 0.458 0.89 0.8 IB V A mp 1E-3 1E-3 1E-3 CJO Farad 0.4E-12 0.4E-12 56E-12 TT sec 2.541E-9 2.541E-9 2.541E-9 M -- 0.01 0.01 0.23 N -- 1.1 1.1 1.1 EG eV 1.11 1.11 1.11 5 www.semtech.com RClamp0521P PRELIMINARY PROTECTION PRODUCTS Outline Outline Drawing Drawing- -SO-8 SLP1006P2 A B D E DIM TOP VIEW A SEATING PLANE aaa C C A1 A A1 b D E e L R N aaa bbb DIMENSIONS MILLIMETERS INCHES MIN NOM MAX MIN NOM MAX .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.
