RClamp0501T
Low Capacitance
1-Line ESD protection
Description Features
Dimensions Schematic & PIN Configuration
Revision 11/02/2010
RailClamp® TVS arrays are ultra low capacitance ESD
protection devices designed to protect high speed
data interfaces. This series has been specifically
designed to protect sensitive components which are
connected to high-speed data and transmission lines
from overvoltage caused by ESD (electrostatic dis-
charge), CDE (Cable Discharge Events), and EFT
(electrical fast transients).
The RClamp®0501T has a maximum capacitance of
only 1.5pF. This allows it to be used on circuits operat-
ing in excess of 100MHz without signal attenuation.
They may be used to meet the ESD immunity require-
ments of IEC 61000-4-2.
The RClamp0501T is in a 2-pin SLP1006P2T package
measuring 1.0 x 0.6 x 0.4mm. The leads are spaced
at a pitch of 0.65mm and feature a lead-free finish.
Each device will protect one high-speed line operating
at 5 volts. It gives the designer the flexibility to protect
single lines in applications where arrays are not practi-
cal. The combination of small size, low capacitance,
and high ESD surge capability makes them ideal for
protection of high speed digital lines in cellular hand-
sets and other portable electronic devices.

Device Connection Options
These low capacitance TVS diodes are designed to
provide common mode protection for one high-speed
line. The device is unidirectional and may be used on
lines where the signal polarity is positive.
Circuit Board Layout Recommendations for Suppres-
sion of ESD.
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:
zPlace the TVS near the input terminals or connec-
tors to restrict transient coupling.
zMinimize the path length between the TVS and the
protected line.
zMinimize all conductive loops including power and
ground loops.
zThe ESD transient return path to ground should be
kept as short as possible.
zNever run critical signals near board edges.
zUse ground planes whenever possible.
