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
0521P 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 RClamp0521P is in a 2-pin 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 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.
