The EClamp
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 RST 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 EClamp2455K is in a 8-pin, RoHS/WEEE compli-
ant, SLP1713P8 package. It measures 1.7 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 and digital still cameras.
