RClamp0582B
Low Capacitance TVS
for ESD and Surge Protection
PROTECTION PRODUCTS - RailClamp®
Description
Features
‹ Transient protection for high-speed data lines to
RailClamp® TVS diodes are 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).
The RClamp®0582B 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). This means it can be used on high-speed interfaces such as USB 2.0 and LVDS data lines. 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. They are designed for use in applications where
board space is at a premium. The combination of small
size, low capacitance, and high level of surge protection
makes them a flexible solution for applications such as
set top boxes, displays, and portable electronics.

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.
