General 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 compli-
ant 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.
