描述 Description

RailClamp? 3552T is a low voltage RailClamp which can provide ESD protection to IEC 61000-4-2 on highspeedports. It is manufactured using Semtech's proprietary low voltage technology, designed to minimize both the ESD peak clamping and TLP clamping voltage. 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.
