Product Description
The CSPEMI307A is a multichannel EMI/ESD array
offering a combination of four low-pass filter + ESD
channels to reduce EMI/RFI emissions on a data port
and four dedicated ESD-only channels intended specif-
ically for ESD protection on a USB port. Each EMI/RFI
channel integrates a high quality pi-style filter (C-R-C)
which provides greater than 30dB attenuation in the
800-2700 MHz range. These pi-style filters support
bidirectional filtering, controlling EMI both to and from a
data port connector.
The CSPEMI307A provides a high-level of ESD protec-
tion on all eight channels for sensitive electronic com-
ponents that may be subjected to electrostatic
discharge (ESD). The input pins are designed and
characterized to safely dissipate ESD strikes of 15kV,
exceeding the maximum requirement of the IEC
61000-4-2 international standard. Using the MIL-STD-
883 (Method 3015) specification for Human Body
Model (HBM) ESD, the device provides protection for
contact discharges to greater than 30kV.
The CSPEMI307A is particularly well suited for porta-
ble electronics (e.g., cellular telephones, PDAs, note-
book computers) because of its small package footprint
and low weight. The CSPEMI307A is available in a
space-saving, low-profile Chip Scale Package with
optional lead-free finishing.

Specifications
Note 1: T

=25
C unless otherwise specified.
Note 2: ESD applied to input and output pins with respect to GND, one at a time.
Note 3: Clamping voltage is measured at the opposite side of the EMI filter to the ESD pin. For example, if ESD is applied to Pin A2,
then clamping voltage is measured at Pin C2.
Note 4: Unused pins are left open
Note 5: These parameters are guaranteed by design and characterization.
