Description
The EClampTM2374P 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 four identical circuits comprised
of TVS diodes for ESD protection, and a resistor -
capacitor network for EMI/RFI filtering. A series
resistor value of 100and a capacitance value of 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 EClamp2374P is in a 8-pin, RoHS compliant,
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.
