RClamp3552TQ
Description
RClamp®3552TQ is a low voltage Rail Clamp which can provide ESD protection to IEC 61000-4-2 on high speed ports. 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 0.3 Ohms, further minimizing the ESD clamping. Maximum capacitance is only 0.4p F allowing the RClamp3552TQ to be used in applications operating in excess of 6 GHz without appreciable signal attenuation. Each device will protect two lines operating at 3.5 volts.
RClamp3552TQ is in a DFN 1.0 x 0.6 x 0.40 mm 3-Lead package. The bination of low peak ESD clamping, low dynamic resistance, and low capacitance makes this device suitable for applications such as USB 3.1 Gen 1, LVDS,...
