PROTECTION PRODUCTS
Description
RailClamps are ultra low capacitance Transient Voltage
Suppressors (TVS) 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 discharge),
CDE
(Cable
Discharge Events), and
EFT
(electrical fast transients).
The RClamp
TM
0521P has a maximum capacitance of
only 0.50pF. This allows it to be used on circuits operat-
ing in excess of 3GHz without signal attenuation. They
may be used to meet the ESD immunity requirements of
IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact
discharge).
The RClamp0521P is in a 2-pin, RoHS/WEEE compliant,
SLP1006P2 package measuring 1.0 x 0.6 x 0.5mm.
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 practical. The combination of small size,
low capacitance, and high ESD surge capability makes
them ideal for use in applications such as cellular
phones and digital video interfaces.
