Overview
RClamp®1561PQ is a low capacitance ESD protection device specifically designed to protect high power RF interfaces. It offers desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation.
RClamp1561PQ is bidirectional and features a working voltage of 15V, high ESD withstand voltage (+/-10kV contact per IEC 61000-4-2), and low typical capacitance (0.25pF at VR=15V). RClamp1561PQ has been specifically engineered to minimize harmonic distortion in RF circuits, including high and low GSM bands. This makes it ideal for use on RF, FM, GSM and other antenna circuits commonly found in mobile and automotive applications.
RClamp1561PQ is in a 2-pin SLP1006P2 package measuring 1.0 x 0.6 mm with a nominal height of only 0.50mm. Leads are finished with NiPdAu. This device is qualified to AEC-Q100.
