UM8411/8411Z

8 Line ESD/EMI Protection for Color LCD Interfaces

UM8411/8411Z DFN16 3.3×1.3

General Description

The UM8411/8411Z 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 silicon-avalanche technology

for superior clamping performance and DC electrical characteristics. It has been optimized for

protection of color LCD panels in cellular phones and other portable electronics.

The device consists of eight identical circuits comprised of TVS diodes for ESD protection, and a

RC network for EMI filtering. A series resistor value of 100Ω and a capacitance value of 10pF are

used to achieve 25dB minimum attenuation from 800 MHz 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 UM8411/8411Z is in a 16-pin, RoHS compliant DFN16 package. It measures 3.3mm ×

1.3mm. The leads are spaced at a pitch of 0.4 mm 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

PDAs.
