The EClamp
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
LCD panels
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
10pF are used to achieve 30dB minimum attenuation
from 1.8GHz 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 EClamp2378P is in a 16-pin, RoHS/WEEE compli-
ant, SLP4016P16 package. It measures 4.0 x 1.6 x
0.58mm. The leads are spaced at a pitch of 0.5mm
and are finished with lead-free NiPd. The small pack-
age makes it ideal for use in portable electronics such
as cell phones, digital still cameras, and PDAs.
