CSPEMI307A 4-Channel ESD/EMI Filter Array plus 4-Channel ESD Array for USB
Features
• • • • • • Four channels of combined EMI/RFI filtering + ESD protection Four additional channels of ESD-only protection EMI/ESD channels provide greater than 32dB attenuation at 1GHz +15kV ESD protection on all channels (IEC 61000-4-2 Level 4, contact discharge) + 30kV ESD protection on all channels (HBM) Chip Scale Package features extremely low lead inductance for optimum filter and ESD performance 15-bump, 2.960mm X 1.330mm footprint Chip Scale Package (CSP) Lead-free version available
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 specifically 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 protection on all eight channels for sensitive electronic components 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-STD883 (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 portable electronics (e.g., cellular telephones, PDAs, notebook 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.

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.
