The EClamp
®
2515K is combination EMI filter and line
termination device with integrated TVS diodes for use
on Multimedia Card interfaces. This device utilizes
solid-state silicon-avalanche technology for superior
clamping performance and DC electrical characteris-
tics. They have been optimized for

The device consists of six circuits that include series
impedance matching resistors and pull up resistors as
required by the SD specification. TVS diodes are
included on each line for ESD protection. Each data
line has a typical capacitance of 22pF while the clock
line has a typical capacitance of only 12pF. An addi-
tional TVS diode connection is included for protection
of the voltage (Vdd) bus. A 45 Ohm termination resis-
tor is included on the DAT0, DAT1, DAT2, DAT3, CMD,
and CLK lines. Pull up resistors of 15k Ohms are
included on DAT0, DAT1, DAT2, DAT3, and CMD lines.
The TVS diodes provide effective suppression of ESD
voltages in excess of ±15kV (air discharge) and ±12kV
(contact discharge) per IEC 61000-4-2.
The EClamp2515K is in a 16-pin SLP3313P16 pack-
age. It measures 3.3 x 1.3 x 0.50mm. The leads are
spaced at a pitch of 0.4mm and are finished with lead-
free NiPdAu.
