RClamp0521P
Ultra-Low Capacitance
1-Line ESD protection
Description Features
Dimensions Schematic & PIN Configuration
Revision 01/12/2010
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®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 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.
