RCLAMP3552TQTNT

RClamp3552TQ is a low voltage RailClamp 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 0.4pF 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. RClamp3552TO is in a DFN 1.0×0.6×0.40mm 3 - Lead package. The combination 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, audio, and V - By - One interfaces.
