RClamp1255P
Low Capacitance RClamp®
Surge Protection for uUSB Interfaces
PROTECTION PRODUCTS - RailClamp®
Description
RailClamp® TVS arrays are low capacitance ESD
protection devices designed to protect high speed data
interfaces. The RClamp®1255P provides dedicated
surge and ESD protection for uUSB ports. It is de-
signed to replace multiple discrete components in
portable applications. This device features low capaci-
tance 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 ±10kV contact
discharge per IEC 61000-4-2. Loading capacitance on
these lines is <0.50pF. An integrated 12 volt TVS
diode is used for protection of the USB voltage bus.
The VBus TVS is designed with a high surge current
capability of 100A (tp=8/20us) and low clamping
voltage.
The RClamp1255P is in a 6-pin SLP2018P6 package. It
measures 2.0 x 1.8mm with a nominal height of 0.57mm.
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 mo-
bile phones, laptops, and other portable electonics.
