for SIM Card
Description Features
Package Configuration
8 Pin SLP package (Bottom Side View)
Nominal Dimensions in mm
The EClampTM2455P is 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 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 EClamp2455P is in a 8-pin, RoHS/WEEE compliant,
SLP2116P8 package. It measures 2.1 x 1.6 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
such as cell phones and digital still cameras.

EClamp2455P
Device Connection
The EClamp2455P designed with ease of layout in
mind. The package has flow through design which
allows the designer to route the signals straight in and
out between the SIM port connector and the SIM
controller. The device is in a 8-pin SLP package.
Electrical connection is made to the 8 pins located at
the bottom of the device. A center tab serves as the
ground connection. Pin connections are noted in
Figure 1. All path lengths should be kept as short as
possible to minimize the effects of parasitic inductance
in the board traces.
