PPRROOwwTTwEE.DCCaTTtaIISOOheNNet4PPU.RRcoOmODDUUCCTTSS - RailClamp®
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 RClampTM1521P has a maximum capacitance of
only 0.5pF. 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 RClamp1521P 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 15 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 high-power USB.
