RClamp2654P
Low Capacitance RClamp®
Surge Protection for USB Interfaces
PROTECTION PRODUCTS - RailClamp®
Description
PRELIMINARY
Features
RailClamp® TVS arrays are low capacitance ESD
protection devices designed to protect high speed data
interfaces. The RClamp®2654P provides dedicated
surge and ESD protection for uUSB ports. It is designed to replace multiple discrete components in
portable applications. This device features low capacitance TVS diodes for protection of the USB data (DP,
DM) and USB ID pins operating up to 4 volts. These
diodes provide ESD protection to ±15kV contact
discharge per IEC 61000-4-2. Loading capacitance on
these lines is <0.80pF. An integrated 26 volt TVS
diode is used for protection of the USB voltage bus.
The VBus TVS is designed with a high surge current
capability of 80A (tp=8/20us) and low clamping voltage.
The RClamp2654P is in a 10-pin SLP2626P10 package.
It measures 2.6 x 2.6mm with a nominal height of
0.60mm. This highly integrated device requires less board
space than existing solutions.
The combination of small size, low capacitance, and high
level of surge and ESD protection makes this device a
flexible solution for protection of USB interfaces in mobile phones, laptops, and other portable electonics.

Applications Information
Device Connection and Layout Options for Protecting
One USB Port
The RClamp2654P is optimized for protection of USB
ports. Low capacitance protection is provided for the
USB data (DM, DP) and USB ID lines at pins 4, 5, and
6. These inputs are referenced to an internal 4 volt
TVS protection device. When the voltage on these
lines exceed 4 volts, the TVS will conduct. Pins 1, 2,
and 3 are connected to the USB voltage bus (VBus).
These three pins must be shorted together on the PCB
otherwise the maximum surge capability of the device
will be reduced. The VBus TVS has a minimum
breakdown voltage of 28V at 1mA. Ground is provided
at the center tab. Multiple micro vias connected to
ground are recommended for best ESD performance.
This will reduce parasitic inductance in the ground path
and minimize the clamping voltage seen by the
protected device.
