PPRROOTTEECCTTIIOONN _{PPRROODDUUCCTTSS - RailClamp}^®
Description
RailClamp is an ultra low capacitance Transient Voltage
Suppressor (TVS) designed to protect high speed data
interfaces. This device has been specifically designed
to protect sensitive components which are connected
to high-speed data and transmission lines from over-
voltage caused by ESD (electrostatic discharge), CDE
(Cable Discharge Events), and EFT (electrical fast
transients).
The RClamp^TM0531T has a maximum capacitance of
only 0.80pF. This allows it to be used on circuits
operating in excess of 2.5GHz without signal attenua-
tion. They may be used to meet the ESD immunity
requirements of IEC 61000-4-2.
The RClamp0531T 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
use in applications such as cellular phones and digital
video interfaces.
