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 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 100Ω and 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 EClamp2374K is in a 8-pin, RoHS/WEEE compliant,

SLP1713P8 package. It measures 1.7 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.
