UM8601 Datasheet | Union Semiconductor

Description UM8611 DFN16 3.3×1.3 The UM4601/UM4611/UM8601/UM8611 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. They have been optimized for protection of color LCD and camera lines in cellular phones and other portable electronics. The device consists of identical circuits prised of TVS diodes for ESD protection, and an inductor - capacitor network for EMI filtering. A typical inductor value of 17n H and a capacitor value of 15p F are used to achieve 24d B minimum attenuation from 800MHz to 2.7GHz. The TVS diodes provide effective suppression of ESD voltages in excess of ±15k V (air discharge) and ±8k V (contact discharge) per IEC 61000-4-2, level 4. The UM4601 is in a Ro HS pliant DFN8 2.0×2.0 package, the UM4611 is in a Ro HS pliant DFN8 1.7×1.3 package, the UM8601 is in a Ro HS pliant DFN16 4.0×1.6 package and the UM8611 is in a Ro HS pliant DFN16 3.3×1.3 package. The leads are finished with lead-free. The small package makes it ideal for use in portable electronics such as cell phones, digital still cameras, and PDAs.
