6 Line ESD/EMI Protection for Color LCD Interfaces
UM6411 DFN12 2.5 X 1.3
General Description
The UM6411 is a low pass filter array with integrated TVS diodes. It is designed to suppress
unwanted EMI/RFI signals and provide electrostatic discharge (ESD) protection in portable electronic
equipment. This state-of-the-art device utilizes solid-state silicon-avalanche technology for superior
clamping performance and DC electrical characteristics. They have been optimized for protection of
color LCD panels in cellular phones and other portable electronics. The device consists of six
identical circuits comprised of TVS diodes for ESD protection, and a resistor -capacitor network for
EMI/RFI filtering. A series resistor value of 100Ω and a capacitance value of 10pF are used to
achieve 30dB minimum attenuation from 800MHz to 2.5GHz. 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 UM6411 is in a 12-pin, RoHS compliant, DFN12 2.5mmx1.3mm
package. The leads are spaced at a pitch of 0.4mm and are finished with lead-free Ni Pd. The small
package makes it ideal for use in portable electronics such as cell phones, digital still cameras, and
