RClamp0504N RailClamp Low Capacitance TVS Diode Array PROTECTION PRODUCTS - RailClamp Features Description RailClamps are surge rated diode arrays designed to ESD protection for high-speed data lines to protect high speed data interfaces. The RClamp series IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) has been specifically designed to protect sensitive IEC 61000-4-4 (EFT) 40A (5/50ns) components which are connected to data and trans- IEC 61000-4-5 (Lightning) 12A (8/20s) mission lines from overvoltage caused by electrostatic Array of surge rated diodes with internal TVS Diode discharge (ESD), electrical fast transients (EFT), and Small package saves board space lightning. Protects four I/O lines The unique design of the RClamp series devices Low capacitance: 3pF typical incorporates eight surge rated, low capacitance steer- Low clamping voltage ing diodes and a TVS in a single package. During Low operating voltage: 5.0V transient conditions, the steering diodes direct the Solid-state silicon-avalanche technology transient to either the positive side of the power supply Mechanical Characteristics line or to ground. The internal TVS diode prevents over-voltage on the power line, protecting any down- SLP2020P6 Package stream components. RoHS/WEEE Compliant TM The RClamp 0504N has a low typical capacitance of Nominal Dimensions: 2.0 x 2.0 x 0.60 mm 3pF and operates with virtually no insertion loss to Lead Pitch: 0.65mm 1GHz. This makes the device ideal for protection of Lead Finish: NiPdAu high-speed data lines such as USB 2.0, Firewire, DVI, Marking : Marking Code and Date Code and gigabit Ethernet interfaces. Packaging : Tape and Reel The RClamp0504N is in a 6-pin, RoHS compliant, SLP2020P6 package. It measures 2.0 x 2.0 x Applications 0.60mm. The leads are spaced at a pitch of 0.5mm USB 2.0 Power and Data Line Protection and are finished with lead-free NiPdAu. Each device Video Graphics Cards may be used to protect four high-speed data or trans- Monitors and Flat Panel Displays mission lines. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 Digital Video Interface (DVI) (15kV air, 8kV contact discharge). 10/100/1000 Ethernet Notebook Computers Circuit Diagram Package Dimensions 2.00 1 Pin 5 2.00 Pin 1 Pin 3 Pin 4 Pin 6 0.65 BSC Pin 2 0.60 6 Pin SLP package (Bottom Side View) Device Schematic Nominal Dimensions in mm www.semtech.com Revision 01/16/2008 1RClamp0504N PROTECTION PRODUCTS Absolute Maximum Rating Rlating Seymbo Vsalu Unit PPeak Pulse Power (tp = 8/20s) 3s00 Watt pk PIeak Pulse Current (tp = 8/20s) 1A2 PP ESD per IEC 61000-4-2 (Air) V 15 kV ESD ESD per IEC 61000-4-2 (Contact) 8 OTperating Temperature -C55 to +125 J STtorage Temperature -C55 to +150 STG o Electrical Characteristics (T = 25 C) RClamp0504N Plarameter SsymboCmondition MlinimuTmypicaMsaximu Unit RVeverse Stand-Off Voltage P5in 5 to 2 V RWM RVeverse Breakdown Voltage I = 1mA6V BR t Pin 5 to 2 RIeverse Leakage Current V = 5V, T=25C 5A R RWM Pin 5 to 2 FVorward Voltage I=215mA 1V.
