Description
Esd/emi Protection For Color Lcd Interfaces
Manufacturer
Semtech Corporation
Datasheet
The EClamp
integrated TVS diodes. It is designed to suppress un-
wanted EMI/RFI signals and provide electrostatic dis-
charge (ESD) protection in portable electronic equip-
ment. This state-of-the-art device utilizes solid-state
silicon-avalanche technology for superior clamping
performance and DC electrical characteristics. It has
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 resistor -
capacitor network for EMI/RFI filtering. A series
resistor value of 200Ω and a capacitance 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 EClamp2388K is in a 16-pin, RoHS/WEEE compli-
ant, SLP3313P16 package. 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.
