RClamp3324P Low Capacitance RailClamp®
4-Line Surge and ESD Protection
PROTECTION PRODUCTS
Description Features RailClamp® 3324P provides ESD protection for highspeed data interfaces. It features a high maximum ESD
withstand voltage of ±17kV contact and ±20kV air
discharge per IEC 61000-4-2. RClamp3324P 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 RClamp3324P to be
used in applications operating in excess of 5GHz without
signal attenuation. Each device will protect up to four
lines (two high-speed pairs). • Transient Protection to
IEC 61000-4-2 (ESD) 20kV (Air), 17kV (Contact)
IEC 61000-4-4 (EFT) 4kV (5/50ns)
