I. Device Description
A. General
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. They have been optimized
for protection of color LCD and camera lines in cellular phones and other portable electronics.
The device consists of eight identical circuits comprised of TVS diodes for ESD protection, and
a C-L-C network for EMI filtering. A typical inductor value of 17nH and a capacitor value of
12pF are used to achieve 19dB 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.
