UM8511 Datasheet | Union Semiconductor

Multi-Line ESD/EMI Protections for Signal Lines UM8511 DFN16 3.3×1.3 General Description The UM8511 is a (L-C) low pass filter array with integrated TVS diodes. It is designed to suppress unwanted EMI signals and provide electrostatic discharge (ESD) protection in portable electronic equipment. This device utilizes solid-state silicon-avalanche technology for superior clamping performance and DC electrical characteristics. It has been optimized for protection of signal lines in cellular phones and other portable electronics. The device consists of identical circuits prised of TVS diodes for ESD protection, and a C-L-C network for EMI filtering. A typical inductor value of 17nH...
