PROTECTION PRODUCTS - RailClamp®
Description
Features
‹ Transient protection for high-speed data lines to
The RClamp®0582BQ transient voltage suppressor is
specifically 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 configured 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 finish. 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 flexible
solution for protection of USB 2.0, LVDS, and video interfaces.

Figure 1. Pin Configuration
Device Connection Options
This device is optimized for protection of two high
speed dta lines. The device is connected as follows:
Protection of two lines is achieved by connecting data
lines at pins 1 & 2. Pin 3 is connected to ground. The
connection to ground should be made directly to a
ground plane. The path length should also be kept as
short as possible to minimize parasitic inductance.
Matte Tin Lead Finish
Matte tin has become the industry standard lead-free
replacement for SnPb lead finishes. A matte tin finish
is composed of 100% tin solder with large grains.
Since the solder volume on the leads is small compared to the solder paste volume that is placed on the
land pattern of the PCB, the reflow profile will be
determined by the requirements of the solder paste.
Therefore, these devices are compatible with both
lead-free and SnPb assembly techniques. In addition,
unlike other lead-free compositions, matte tin does not
have any added alloys that can cause degradation of
the solder joint.
