RClamp1654P
RailClamp®
Low Capacitance TVS Array
PROTECTION PRODUCTS - RailClamp®
Features
Description
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).
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 (1.6 x 1.6mm) saves board space
Protects USB DP, DM, and ID Pin operating up to
5.5V
The RClamp1654P is specifically designed to protect
portable devices that utilize the USB port for battery
charging. The unique design of this device features low
capacitance TVS diodes for protection of the USB data
(DP, DM) and USB ID (accessory detect) pins operating
up to 5 volts. Loading capacitance on these lines is
<1pF for maximum signal integrity. An integrated 12
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. Leakage current of
the VBus protection is <50nA when operating at 12
volts.
Protects USB VBus operating up to 12V
Low capacitance (<1pF) on DP, DM, and ID Pins
Minimal insertion loss to 2.0GHz
Low leakage current
Low clamping voltage
Large ground pad for increased ESD performance
Solid-state silicon-avalanche technology
