The RClamp0504N is a 5.0-V protection device aimed at next-generation monitors, laptops, set-top boxes, and networking equipment using high-speed I/O protocols. Developed by Semtech, the part measures just 2.0 by 2.0 by 0.6 mm. It features an array of surge-rated steering diodes and a low-voltage TVS diode and protects up to four data lines. The 3-pF typical capacitance allows it to operate with no insertion loss to 1 GHz.
The device is in a leadless package, which is 66% smaller than competitive parts. As it result, it can be used in USB or Ethernet cable connectors, protecting monitors, laptops and other small systems where board space is at a premium.
The RClamp0504N meets the following IEC requirements: IEC 61000-4-2 (ESD) +/-15 kV (air) and +/-8 kV (contact); IEC 61000-4-4 (EFT) 40 A (5/50 ns); and IEC 61000-4-5 (lightning) 12 A (8/20 Μs). It's available now in production quantities and is priced at $0.51 each in 1000-piece lots. More information is available at www.semtech.com.
