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.

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.
