Description
The RailClamp family is a series of ultra low capacitance
Transient Voltage Suppressors (TVS) designed to protect
high speed data interfaces. This series has been specifi-
cally 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^TM0821P has a maximum capacitance of
only 0.50pF. This allows it to be used on circuits
operating in excess of 3GHz without signal attenua-
tion. They may be used to meet the ESD immunity
requirements of IEC 61000-4-2, Level 4 (±15kV air,
±8kV contact discharge).
The RClamp0821P 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 8 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.
