PROTECTION PRODUCTS - EMIClampTM
Description
The EClampTM3202A is a low pass filter array with
integrated TVS diodes for ESD protection. It is de-
signed to provide bidirectional filtering of EMI/RFI
signals and electrostatic discharge (ESD) protection in
portable electronic equipment. This state-of-the-art
device utilizes solid-state silicon-avalanche technology
for superior clamping performance and DC electrical
characteristics. They have been optimized for use on a
microphone port in cellular phones and other protable
electronics. The EClamp3202A effectively replaces 10
discrete components in a small SC-89 package to
provide ESD protection and EMI filtering. Each device
requires less than 2.9mm2 of PCB area with a low
profile of only 0.60mm. This small package will protect
and filter up to two lines. This small outline makes the
device especially well suited for portable applications.
The TVS diodes are bidirectional for supporting bipolar
audio signals without distortion. 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 device has very low insertion
loss in the pass band and high attenuation at frequen-
cies ranging from 800MHz to 3GHz. Each line features
two stages of TVS diode protection. They feature large
cross-sectional area junctions for conducting high tran-
sient currents. They offer desirable characteristics for
board level protection including fast response time, low
operating and clamping voltage, and no device degrada-
tion.
