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).
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.
The RClamp1654P is in a 6-pin, RoHS compliant,
SLP1616P6 package. It measures 1.6 x 1.6 x
0.60mm. 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).
