RClamp2654P
Low Capacitance RClamp®
Surge Protection for USB Interfaces
PRELIMINARY
PROTECTION PRODUCTS - RailClamp®
Features
Description
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 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 ±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 volt-
age.
