RClamp0552T Ultra Low Capacitance TVS 2-Line ESD Protection PROTECTION PRODUCTS - RailClamp® Description Features RailClamp TVS arrays are ultra low capacitance ESD protection devices designed to protect high speed data interfaces. They are designed to replace 0201 size multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and other portable electronics. This device offers desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. The RClamp®0552T has a maximum capacitance of only 0.40pF. This allows it to be used on circuits operating in excess of 5GHz without signal attenuation. The RClamp0552T is in a 3-pin SLP1006N3T package. It measures 1.0 x 0.6 mm with a nominal height of only 0.4mm. The leads are finished with lead-free NiPdAu. Each device will protect two lines operating at 5 volts. It gives the designer the flexibility to replace multiple single line devices in space constrained applications. They may be used to meet the ESD immunity requirements of IEC 61000-4-2. The combination of small size and high ESD surge capability makes them ideal for use in portable applications such as cellular phones, digital cameras, and MP3 players. ® High ESD withstand Voltage: +/-17kV (Contact and Air) per IEC 61000-4-2 Very small PCB area: 0.6mm2 Protects up to two high-speed data lines Low reverse current: <5nA typical (VR=5V) Working voltage: +/- 5V Low capacitance: <0.4pF (VR=0V) Low dynamic resistance: 0.90 Ohms (Typ) Solid-state silicon-avalanche technology Mechanical Characteristics SLP1006N3T package Pb-Free, Halogen Free, RoHS/WEEE Compliant Nominal Dimensions: 1.0 x 0.6 x 0.40 mm Lead Finish: NiPdAu Molding compound flammability rating: UL 94V-0 Marking : Marking code + dot matrix date code Packaging : Tape and Reel Applications Dimensions HDMI 1.3 and HDMI 1.4 USB 3.0 MHL eDP LVDS Interfaces eSATA Interfaces Schematic & PIN Configuration 1 1.00 0.68 1 2 2 0.60 0.40 3 Nominal Dimensions (mm) Revision 3/19/2013 2-Line, Bidirectional 1 www.semtech.com RClamp0552T PROTECTION PRODUCTS Absolute Maximum Rating R ating Symbol Value Units Peak Pulse Power (tp = 8/20μs) Pp k 60 Watts Maximum Peak Pulse Current (tp = 8/20μs) Ip p 3 Amps VESD +/- 17 +/- 17 kV TJ -55 to +125 °C TSTG -55 to +150 °C ESD per IEC 61000-4-2 (Air)1 ESD per IEC 61000-4-2 (Contact)1 Operating Temperature Storage Temperature Electrical Characteristics (T=25oC) Parameter Symbol Conditions Reverse Stand-Off Voltage VRWM Any I/O Pin to GN D Reverse Breakdown Voltage V BR It = 1mA Any I/O Pin to GN D Reverse Leakage Current IR Reverse Leakage Current Minimum Maximum Units 5 V 9 11 V VRWM = 2V, T=25°C Any I/O Pin to GN D <5 20 nA IR VRWM = 5V, T=25°C Any I/O Pin to GN D <55 100 nA Clamping Voltage VC IPP = 3A, tp = 8/20μs Any I/O Pin to GN D 20 V ESD Clamping Voltage2 VC IPP = 16A, tlp = 0.2/100ns 24.5 V Dynamic Resistance2, 3 RDyn tp = 100ns 0.90 Ohms Junction Capacitance Cj VR = 0V, f = 1MHz Any I/O Pin to GN D 0.21 6.5 Typical 0.4 pF Notes 1)ESD gun return path connected to ESD ground reference plane. 2)Transmission Line Pulse Test (TLP) Settings: tp = 100ns, tr = 0.2ns, ITLP and VTLP averaging window: t1 = 70ns to t2 = 90ns. 3) Dynamic resistance calculated from ITLP = 4A to ITLP = 16A 4)Guaranteed by design.

The device is bidirectional and may be used on lines where the signal polarity is above and below ground. The diagram at the right shows an example pin configuration with pin 3 connected to ground. However, due to the device symmetry, any pin may be connected to ground with the remaining pins conneted to the protected lines.
