RCLAMP0504P Datasheet, PDF (1/9 Pages) Semtech Corporation – RailClamp® Low Capacitance TVS Array

PROTECTION PRODUCTS - RailClamp^
Description
RailClamps^ are low capacitance TVS arrays 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 unique design incorporates surge rated, low
capacitance steering diodes and a TVS diode in a
single package. During transient conditions, the
steering diodes direct the transient current to ground.
The internal TVS diode clamps the transient voltage to
a safe level. The low capacitance array configuration
allows the user to protect up to four high-speed data
lines.
The RClamp0504P 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).
The combination of small size, low capacitance, and high
ESD surge capability makes them ideal for use in por-
table applications such as cellular phones, next genera-
tion color LCD displays, USB, and multi media card
interfaces.
