PROTECTION PRODUCTS - EMIClampTM
Description
The EClampTM2394P is a (L-C) 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 and camera lines in cellular phones and other
portable electronics.
The device consists of four identical circuits comprised
of TVS diodes for ESD protection, and a 5-pole induc-
tor - capacitor network for EMI/RFI filtering. A typical
inductor value of 19nH and a capacitor value of 12pF
are used to achieve 30dB 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 EClamp2394P is in a 8-pin, RoHS/WEEE compli-
ant, SLP2116P8 package. It measures 2.1 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.
