Description
The EClampTM2465T is a combination EMI filter and line
termination device with integrated TVS diodes for use on
SIM Card interfaces on cellular phones and other por-
table electronics. This state-of-the-art device utilizes
solid-state silicon-avalanche technology for superior
clamping performance and DC electrical characteristics.
The device consists of three circuits that include series
impedance matching resistors for proper termination of
the SIM card interface. Termination resistor value of
100 Ohms is included on the Reset and Data lines and
47 Ohms on the CLK line. TVS diodes are also included
on each line for ESD protection in excess of ±15kV (air
discharge) and ±8kV (contact discharge) per IEC 61000-
4-2, level 4. An additional TVS diode connection is
included for protection of the voltage (Vcc) bus.
The EClamp2465T is in a 8-pin, RoHS/WEEE compliant,
SLP1713P8T package. It measures 1.7 x 1.3 mm with
a nominal height of only 0.4mm. 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 and digital still
cameras.
