PROTECTION PRODUCTS - RailClamp®
The RClamp®3346P provides ESD protection for high-
speed data interfaces. It features a high maximum
ESD withstand voltage of ±17kV contact and ±20kV
air discharge per IEC 61000-4-2. RClamp3346P is
designed to minimize both the ESD peak clamping and
the TLP clamping. Package inductance is reduced at
each pin resulting in lower peak ESD clamping voltage.
The dynamic resistance is among the industry’s lowest
at 0.15 Ohms (typical). Maximum capacitance on each
line to ground is 0.65pF allowing the RClamp3346P to
be used in applications operating in excess of 5GHz
without signal attenuation. Each device will protect up
to six lines (three high-speed pairs).
The RClamp3346P is in a 7-pin SGP2708N7 package
measuring 2.7 x 0.8mm with a nominal height of 0.50mm.
The leads have a nominal pin-to-pin pitch of 0.40mm.
Flow- through package design simplifies PCB layout and
maintains signal integrity on high-speed lines.
The combination of low peak ESD clamping, low dynamic
resistance, and innovative package design enables this
device to provide the highest level of ESD protection for
applications such as USB 3.0, eSATA, and DisplayPort.
