RClamp®3374N TVS Diode
Semtech features their RClamp3374N high power TVS diode for Ethernet interfaces
Semtech's RailClamp® TVS diodes are specifically designed to protect sensitive components that are connected to high-speed data and transmission lines from over-voltage caused by ESD (electrostatic discharge), CDE (cable discharge events), and EFT (electrical fast transients). The unique design incorporates surge-rated, low capacitance steering diodes, and a TVS diode in a single package. The RClamp3374N is designed to replace up to two components for board-level GbE protection. Each device is designed to protect two line pairs. This is accomplished by routing traces through the device. When connected in this fashion, the device can withstand a high level of surge current (40 A, 8/20 µs) while maintaining a low loading capacitance of less than 5 pF. The high surge capability means it can be used in high threat environments in applications such as Gigabit Ethernet, telecommunication lines, and LVDS interfaces. The RClamp3374N is constructed using Semtech’s proprietary EPD process technology. The EPD process provides low standoff voltages with significant reductions in leakage current and capacitance over silicon avalanche diode processes. It features a true operating voltage of 3.3 V for superior protection. The RClamp3374N is in a 10-pin SLP3020N10 package. It measures 3.0 mm x 2.0 mm x 0.60 mm. The leads are finished with lead-free NiPdAu.
