ESD/EMI Protection
for Color LCD Interfaces
PROTECTION PRODUCTS - EMIClamp®
PRELIMINARY
Description
Features
The EClamp® 2508K device 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 3-pole induc-
tor - capacitor network for EMI/RFI filtering. A typical
inductor value of 17nH and a capacitor value of 12pF
are used to achieve 20dB 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.
The EClamp2508K is in a 16-pin, SLP3313P16 pack-
age. It measures 3.3 x 1.3 x 0.50mm. The leads are
spaced at a pitch of 0.4mm and are finished with lead-
free NiPdAu. The small package makes it ideal for use
in portable electronics such as cell phones, digital still
cameras, and PDAs.
