EClamp2342N
ESD/EMI Protection
for Color LCD Interfaces
PROTECTION PRODUCTS - EMIClamp TM
Description
The EClamp TM 2342N 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 clamp-
ing 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 eight identical circuits comprised
of TVS diodes for ESD protection, and a resistor -
capacitor network for EMI/RFI filtering. A series
resistor value of 100 ? and a capacitance value of
20pF are used to achieve 30dB minimum attenuation
from 1GHz to 2.5GHz. Each line features two stages of
TVS diode protection. The TVS diodes provide effec-
tive suppression of ESD voltages in excess of 15kV (air
discharge) and 8kV (contact discharge) per IEC 61000-
4-2, level 4.
The EClamp2342N is in a 16-pin, 0.5mm pitch QFN
package. It measures 3.0 x 3.0 x 1.0mm. The small
package makes it ideal for use in portable electronics
such as cell phones, digital still cameras, and PDA’s.
