ECLAMP2422N Datasheet, PDF (1/9 Pages) Semtech Corporation – ESD/EMI Protection for Audio Interfaces

PROTECTION PRODUCTS - EMIClamp^TM
Description
The EClamp^TM2422N is a (C-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. It
has been optimized for protection of headset
audio ports in cellular phones and other portable
electronics.
EClamp2422N
ESD/EMI Protection
for Audio Interfaces
PRELIMINARY
Features
‹ Bidirectional EMI/RFI filter with integrated TVS
for ESD protection
‹ ESD protection to IEC 61000-4-2 (ESD) Level 4,
±15kV (air), ±8kV (contact)
‹ TVS working voltage: 5V
‹ Inductor: 2nH (Typical)
‹ Capacitors: 100pF (Typical at VR = 0V)
‹ Protection and filtering for two lines
‹ Solid-state technology
The device consists of two identical circuits comprised of
TVS diodes for ESD protection, and a C-L-C pi-filter for
EMI/RFI filtering. A typical inductor value of 2nH and a
capacitor value of 100pF are used to achieve 20dB
minimum attenuation from 800MHz to 2.7GHz. It has a
very low series resistance of 2 Ohms, making it ideal for
use on headset speaker interfaces. 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 EClamp2422N is in a 6-pin, RoHS/WEEE compliant,
SLP1510N6 package. It measures 1.45 x 1.0 x
0.58mm. The leads are spaced at a pitch of 0.5mm
and are finished with lead-free NiPdAu. The small
package makes it ideal for use in portable electronics.
