RClamp0503N RailClamp® Low Capacitance TVS Diode Array PROTECTION PRODUCTS - RailClamp® Description Features The RailClamp series is a family of ultra low capacitance TVS arrays 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). They are designed for use in applications where board space is at a premium. Each device requires less than 1.5mm2 of PCB area and will protect up to three high speed data lines. ESD protection for high-speed data lines to The monolithic design incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. Each line has a maximum capacitance of 0.5pF to ground. The capacitance of each line is well matched for consistant signal balance. A connection to the TVS is provided for protection of an external voltage bus, such as those found in USB applications. This device is optimized for ESD protection of portable electronics. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). The RClamp0503N is in a 6-pin, RoHS/WEEE compliant, SLP1510N6 package. It measures 1.45 x 1.0 x 0.58mm. The small package makes it ideal for use in portable electronics such as cell phones, laptops, and digital still cameras. ® IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) Array of surge rated diodes with internal TVS Diode Small package saves board space Protects three I/O lines and a power line Low capacitance: 0.5pF maximum Low clamping voltage Solid-state silicon-avalanche technology Mechanical Characteristics SLP1510N6 Package RoHS/WEEE Compliant Nominal Dimensions: 1.45 x 1.0 x 0.58 mm Lead Pitch: 0.5mm Lead Finish: NiPdAu Marking : Marking Code Packaging : Tape and Reel Applications Circuit Diagram USB OTG MMC Port Serial ATA Video Port SIM Port PCI Express Package Dimensions 1.45 2 1 3 5 1.00 1 3 4 6 6 5 4 0.50 0.58 6 Pin SLP1510N6 package (Bottom Side View) Nominal Dimensions in mm Device Schematic Revision 03/31/2008 1 www.semtech.com RClamp0503N PROTECTION PRODUCTS Absolute Maximum Rating Rating Symbol Value Units Peak Pulse Power (tp = 8/20μs) Ppk 100 Watts Peak Pulse Current (tp = 8/20μs) IPP 3 A ESD per IEC 61000-4-2 (Air) ESD per IEC 61000-4-2 (Contact) VESD ±15 ±8 kV TJ -55 to +125 °C TSTG -55 to +150 °C Operating Temperature Storage Temperature Electrical Characteristics (T = 25oC) R Clamp0503N Parameter Symbol Conditions Reverse Stand-Off Voltage VRWM Pin 5 to GN D Reverse Breakdown Voltage V BR It = 1mA Pin 5 to GN D Reverse Leakage Current IR VRWM = 6.5V, T=25°C Pin 5 to GN D Forward Voltage VF If = 15mA Any I/O to pin 5 Clamping Voltage VC Clamping Voltage Junction Capacitance © 2008 Semtech Corp.

Note that the circuit at the ground pin is identical to the circuit at each data input/output pin. This is done to further reduce capacitance. The connection to ground should be made directly to a ground plane. The path length should also be kept as short as possible to minimize parasitic inductance. Pin 5 can be connected to Vcc biased or left not connected depending upon the application. 5 1 3 4 6 Protecting USB OTG Interfaces Figure 2 - USB OTG Protection The USB OTG interface consists of Data (D- and D+) lines, ID and a 5.25V voltage bus. Since these pins are part of the connector, they are vulnerable to ESD and cable discharge events. The RClamp0503N is designed to protect D-, D+, and ID pins of USB OTG connections. Each device will protect one USB OTG port. When the voltage on the data lines exceeds the bus voltage (plus one diode drop), the internal rectifiers are forward biased conducting the transient current away from the protected controller chip. The TVS diode directs the surge to ground. For Vbus protection, an additional single line TVS, such as uClamp0501P, should be added. © 2008 Semtech Corp.
