Semtech’s RClamp2504N is a 2.5 V protection device designed for lightning surge protection on Ethernet and high-speed digital interfaces. With its high surge capability and ultra-low capacitance, the RClamp2504N provides low-voltage protection for high-speed interfaces found in telecommunications and networking equipment. The low clamping voltage of the RClamp2504N protects communications transceivers from dangerous lightning and ESD threats that are commonly found on networking and telecom equipment. Additionally, the RClamp2504N presents a very low 2 pF (typical) line-to-line capacitance, allowing the device to operate with virtually no insertion loss at speeds up to 2 GHz.

The performance is achieved with enhanced punch-through diode (EPD) process technology. Using the technology, the RClamp2504N meets IEC 61000-4-x protection standards for electrical fast transients (EFT), electrostatic discharge (ESD) and lightning surge. The RClamp2504N is housed in a very small 2.6 mm x 2.6 mm x 0.6 mm SLP package that offers a low-inductance center-ground pad, giving the device additional ability to effectively clamp fast ESD events. Available now, the device is $0.49 each in 1000-piece lots.
