RClamp3655P RailClamp ESD Protection for uUSB Interfaces PROTECTION PRODUCTS - RailClamp Features Description RailClamp is a low capacitance TVS array designed to Transient protection for high-speed data lines to protect high speed data interfaces. This series has IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) been specifically designed to protect sensitive compo- IEC 61000-4-4 (EFT) 40A (5/50ns) nents which are connected to data and transmission Array of surge rated diodes with internal TVS Diode lines from overvoltage caused by ESD (electrostatic Small package saves board space discharge), CDE (Cable Discharge Events), and EFT Protects USB DP, DM, FM radio, and ID Pins to 5V (electrical fast transients). Protects USB VBus operating up to 28V The RClamp3655P is specifically designed to protect Low capacitance (<1pF) on DP, DM, FM and ID Pins portable devices that utilize a uUSB port with an No insertion loss to 2.0GHz2.0GHz2.0GHz 2.0GHz2.0GHz additional FM radio pin. The unique design of this Low leakage current device features low capacitance TVS diodes for protec- Low clamping voltage tion of the USB data (DP, DM), USB ID, and FM radio Innovative package for easy pcb layout pins operating up to 5 volts. Loading capacitance on Solid-state silicon-avalanche technology these lines is <1pF for maximum signal integrity. An integrated 28 volt TVS diode is used for protection of Mechanical Characteristics the USB voltage bus. This ensures the device will SLP3313P6 8L package remain in a high-impedance state during normal USB operation or when the battery is being charged. Leak- RoHS/WEEE Compliant age current of the VBus protection is <250nA when Nominal Dimensions: 3.3 x 1.3 x 0.50 mm operating at 28 volts. Lead Finish: NiPdAu The RClamp3655P is in an 8-pin, RoHS compliant, Molding compound flammability rating: UL 94V-0 SLP3313P6 package. It measures 3.3 x 1.3 x Marking: Marking code 0.50mm. The leads are spaced at a pitch of 0.5mm Packaging: Tape and Reel and are finished with lead-free NiPdAu. They may be Applications used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge). uUSB Interfaces with FM radio Option USB OTG Circuit Diagram PIN Configuration VBus 1 VBat 1 GND Data - 34 5 6 Data + 5V 28V GND ID GND FM Radio SLP3313P6 (Top View) www.semtech.com Revision 07/15/2009 1RClamp3655P PROTECTION PRODUCTS Absolute Maximum Rating Rlating Seymbo Vsalu Unit D)DDDD)PPPPP,,,,, DDDDDMMMMM,,,,, UUUUUSSSSSBBBBB IIIIIDDDDD,,,,, FFFFFMMMMM RRRRRaaaaadddddiiiiiooooo (((((PPPPPiiiiinnnnnsssss 33333,,,,, 44444,,,,, 55555,,,,, 66666))) PPeak Pulse Power (tp = 8/20s) 7s5 Watt pk PIeak Pulse Current (tp = 8/20s) 5A PP ESD per IEC 61000-4-2 (Air) V 18 kV ESD ESD per IEC 61000-4-2 (Contact) 12 OTperating Temperature -C55 to +125 J STtorage Temperature -C55 to +150 STG V)VVVV)BBBBBuuuuusssss (((((PPPPPiiiiinnnnn 11111))) PPeak Pulse Power (tp = 8/20s) 3s50 Watt pk PIeak Pulse Current (tp = 8/20s) 4A PP ESD per IEC 61000-4-2 (Air) V 18 kV ESD ESD per IEC 61000-4-2 (Contact) 12 OTperating Temperature -C55 to +125 J STtorage Temperature -C55 to +150 STG www.semtech.com 2009 Semtech Corp. 2
