EMI Filter with ESD
Protection
Product Description
The EMI7112 is an L−C EMI filter array with ESD protection that
integrates two Pi−filters (C−L−C) to suppress EMI/RFI Noise.
EMI7112 includes ESD protection diodes on all input/output pins, and
provides a very high level of protection for sensitive electronic
components against possible electrostatic discharge (ESD). The ESD
diodes connected to the filter ports safely dissipate ESD strikes of
±30 kV, which is beyond the maximum requirement of the
IEC61000−4−2 international standard.
Features
• Two Channels of EMI Filtering
• ±30 kV ESD Protection (IEC 61000−4−2, Contact Discharge)
• ±30 kV ESD Protection (IEC 61000−4−2, Air Discharge)
• Greater than 45 dB of Attenuation at 900 MHz
• These Devices are Pb−Free and are RoHS Compliant
Applications
• Mobile Phones

NOTE: TLP parameter: Z0 = 50 W, tp = 100 ns, tr = 300 ps, averaging window: t1 = 30 ns to t2 = 60 ns. VIEC is the equivalent voltage
stress level calculated at the secondary peak of the IEC 61000−4−2 waveform at t = 30 ns with 2 A/kV. See TLP description
below for more information.
Transmission Line Pulse (TLP) Measurement
Transmission Line Pulse (TLP) provides current versus
voltage (I−V) curves in which each data point is obtained
from a 100 ns long rectangular pulse from a charged
transmission line. A simplified schematic of a typical TLP
system is shown in Figure 7. TLP I−V curves of ESD
protection devices accurately demonstrate the product’s
ESD capability because the 10s of amps current levels and
under 100 ns time scale match those of an ESD event. This
is illustrated in Figure 8 where an 8 kV IEC 61000−4−2
current waveform is compared with TLP current pulses at
8 A and 16 A. A TLP I−V curve shows the voltage at which
the device turns on as well as how well the device clamps
voltage over a range of current levels.
