RailClamp  
ESD Protection for uUSB Interfaces  
PROTECTION PRODUCTS - RailClamp  
Features  
Description  
‹ Transient protection for high-speed data lines to  
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 USB DP, DM, FM radio, and ID Pins to 5V  
‹ Protects USB VBus operating up to 28V  
‹ Low capacitance (<1pF) on DP, DM, FM and ID Pins  
‹ No insertion loss to 2.0GHz  
‹ Low leakage current  
‹ Low clamping voltage  
‹ Innovative package for easy pcb layout  
‹ Solid-state silicon-avalanche technology  
RailClamp is a low capacitance TVS array designed to  
protect high speed data interfaces. This series has  
been specifically designed to protect sensitive compo-  
nents which are connected to data and transmission  
lines from overvoltage caused by ESD (electrostatic  
discharge), CDE (Cable Discharge Events), and EFT  
(electrical fast transients).  
The RClamp3655P is specifically designed to protect  
portable devices that utilize a uUSB port with an  
additional FM radio pin. The unique design of this  
device features low capacitance TVS diodes for protec-  
tion of the USB data (DP, DM), USB ID, and FM radio  
pins operating up to 5 volts. Loading capacitance on  
these lines is <1pF for maximum signal integrity. An  
integrated 28 volt TVS diode is used for protection of  
the USB voltage bus. This ensures the device will  
remain in a high-impedance state during normal USB  
operation or when the battery is being charged. Leak-  
age current of the VBus protection is <250nA when  
operating at 28 volts.  
Mechanical Characteristics  
‹ SLP3313P6 8L package  
‹ RoHS/WEEE Compliant  
‹ Nominal Dimensions: 3.3 x 1.3 x 0.50 mm  
‹ Lead Finish: NiPdAu  
The RClamp3655P is in an 8-pin, RoHS compliant,  
SLP3313P6 package. It measures 3.3 x 1.3 x  
‹ Molding compound flammability rating: UL 94V-0  
‹ Marking: Marking code  
0.50mm. The leads are spaced at a pitch of 0.5mm  
and are finished with lead-free NiPdAu. They may be  
used to meet the ESD immunity requirements of IEC  
61000-4-2, Level 4 (15kV air, 8kV contact discharge).  
‹ Packaging: Tape and Reel  
Applications  
‹ uUSB Interfaces with FM radio Option  
‹ USB OTG
