Semtech RClamp3346P Low Capacitance RClamp®
Semtech RClamp3346P Low Capacitance RClamp® provides ESD protection for highspeed data interfaces and features a high maximum ESD withstand voltage of ±17kV contact and ±20kV air discharge per IEC 61000-4-2. The RClamp3346P is designed to minimize ESD peak clamping and TLP clamping. Package inductance is reduced at each pin resulting in lower peak ESD clamping voltage. The dynamic resistance is a low 0.15Ω (typical). Maximum capacitance on each line to ground is 0.65pF, allowing the RClamp3346P to be used in applications operating over 5GHz without signal attenuation. Each device will protect up to six lines (three high-speed pairs).
