Product Description  

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 comprised of TVS diodes for ESD protection, and an induc­tor - capacitor network for EMI filtering. A typical inductor value of 17nH and a capacitor value of 15pF are used to achieve 24dB minimum attenuation from 800MHz to 2.7GHz. The TVS diodes provide effective suppression of ESD voltages in excess of ±15kV (air discharge) and ±8kV (contact discharge) per IEC 61000-4-2, level 4.
The UM4601 is in a RoHS compli­ant DFN8 2.0×2.0 package, the UM4611 is in a RoHS compli­ant DFN8 1.7×1.3 package, the UM8601 is in a RoHS compli­ant DFN16 4.0×1.6 package and the UM8611 is in a RoHS compli­ant 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.
