Description
Features
•
High ESD withstand Voltage: +/-17kV (Contact) &
+/-20kV(Air) per IEC 61000-4-2
RClamp®3552T is a low voltage RailClamp which can
provide ESD protection to IEC 61000-4-2 on highspeed
ports. It is manufactured using Semtech’s proprietary
low voltage technology, designed to minimize both the
ESD peak clamping and TLP clampingvoltage. These
devices “snap-back”to a low on-state voltage when the
breakdown voltage of the device is exceeded. This has
the advantage of lowering the overall ESD clamping
voltage. When the device is in the on-state, the dynamic
resistance is typically 0.30 Ohms, further minimizing
the ESD clamping. Maximum capacitance is only 0.40pF
allowing the RClamp3552T to be used in applications
operating in excess of 6GHz without appreciable signal
attenuation. Each device will protect two lines operating
at 3.5 volts.
