NXP multi-channel ESD
protection and EMI filter
IP425xCZ8-4/CZ12-6/CZ16-8
IP4256CZ3-M/CZ5-W/CZ6-F
30 dB EMI filter with up to 30 kV IEC contact
ESD protection in leadless packages
These highly integrated, space-saving devices, housed in NXP’s Ultra Thin Leadless Plastic (ULTP)
package, combine high-level ESD protection with EMI filtering of all relevant 2G and 3G mobilephone,
WLAN and Bluetooth frequencies. The ESD protection exceeds the requirements of the
IEC 61000-4-2 level 4 standard. NXP has 1.000 shot-proven ESD solutions that protect all kinds
of portable applications over their full lifetimes, and provides a complete in-house production
flow for added supply reliability.
Key features of new family
} Up to 30 dB insertion loss at mobile-phone frequencies
(800 MHz to 3 GHz)
} High ESD protection exceeding IEC 61000-4-2 level 4
} Available as 1-, 2-, 4-, 6- or 8-channel filter
} Dark Green-compliant (RoHS-compliant and halogen-/
antimony-free)
} Ultra-thin leadless package, less than 0.5 mm height
} Terminal pitch of 0.4 mm
Key applications
EMI/RFI filtering and downstream ESD
protection in mobile and portable applications
} Camera interface
} Display and LCD interface
} Memory card interface (SD, MMC, etc.)
} Touch or keypad interface
} Bottom connector
Key benefits
} Reduced component count
} Reduced board space
} Easy routing

Clamping voltage of IP4254CZ16-8
at ±8 kV IEC 61000-4-2, level 4 pulse
} Integrated π-filter (C-R-C) structure assures excellent ESD
pulse transient response
Why integrated silicon solutions?
} No degradation – full ESD protection even after 1000 IEC
level strikes
} Predictable, reliable suppression of relevant 2G and 3G
mobile-phone frequencies while minimizing signal loss
} Very low clamping voltage due to optimized π-filter structures
(C-R-C structure)
• Prevent damage of ESD-sensitive circuits during an ESD event (IEC testing only ensures the device will survive)
• Protect against soft errors caused by non-destructive transients
• Protect sensitive system chips
