RClamp0582BQ
Low Capacitance RClamp®
for Automotive Applications
Description
The RClamp®0582BQ transient voltage suppressor is
specically designed to protect sensitive components
which are connected to high-speed data and
transmission lines from overvoltage caused by ESD
(electrostatic discharge), CDE (cable discharge events),
and EFT (electrical fast transients). It is rated to Grade 2
of AEC-Q100 for use in automotive applications.
The RClamp®0582BQ features high peak pulse current
capability (Ipp=15A, tp=8/20us) for use in applications
that require high surge immunity testing. It has a
maximum capacitance of only 1.2pF (pin 1 or 2 to
pin3). They may be used to meet the ESD immunity
requirements of IEC 61000-4-2 (±30kV air, ±25kV
contact discharge). Each device can be congured to
protect 1 bidirectional line or two unidirectional lines.
These devices are in a small SC-75 (SOT-523) package
and feature a lead-free, matte tin nish. They are
compatible with both lead free and SnPb assembly
techniques. The combination of small size, low
capacitance, and high level of surge protection makes
them a exible solution for protection of USB 2.0, LVDS,
and video interfaces.
