Integrated dual channel passive LC-filter network with ESD protection to IEC 61000-4-2 level 4

The IP3047CX6 is a low-Ωic, dual channel LC low-pass filter array which is designed to provide filtering of undesired RF signals. In addition, IP3047CX6 incorporates diodes to provide protection to downstream components from ElectroStatic Discharge (ESD) voltages as high as ±15 kV contact discharge according the IEC 61000-4-2 model, far exceeding standard level 4.

The device is fabricated using monolithic silicon technology and integrates two inductors and four pairs of back-to-back diodes in a 0.5 mm pitch Wafer-Level Chip-Scale Package (WLCSP). These features make the IP3047CX6 ideal for use in applications requiring the utmost in miniaturization such as mobile phone handsets, cordless telephones and other portable electronic devices.
