Overview
The IP4256CZ5-W,115 is a dual-channel passive RC low-pass EMI filter circuit manufactured by Nexperia. It integrates a second-order Pi-type filter network with ElectroStatic Discharge (ESD) protection in a compact SOT-665 surface-mount package. The device features a series channel resistance of 100 Ohms and a channel capacitance of 30 pF at 0 V bias voltage. It provides attenuation of 20 dB from 800 MHz to 3 GHz. The component operates within a temperature range of -40°C to +85°C and is designed for high-level ESD protection up to ±25 kV contact discharge.
Feature Summary
- Integrates a dual-channel second-order passive RC Pi-type low-pass filter network for effective RF interference suppression.
- Provides robust Electrostatic Discharge (ESD) protection exceeding IEC 61000-4-2 Level 4 standards via incorporated diodes.
- Utilizes monolithic silicon technology to combine filtering and protection functions in a single compact surface-mount package.
Applications
- General-purpose Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) filtering
- Downstream ESD protection for cellular phone and Personal Communication System (PCS) mobile handsets
- Wireless data system applications including Wireless Local Area Network (WLAN) and Wireless Wide Area Network (WWAN)
Procurement Notes
Verify the specific suffix '115' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Confirm current lifecycle status as some sources indicate Not Recommended for New Designs (NRND). Ensure compatibility with SOT-665 footprint requirements during procurement planning.
Selection Notes
Select this component when dual-channel signal lines require simultaneous EMI attenuation and ESD protection. The 100 Ohm resistance and 30 pF capacitance values are suitable for high-frequency data lines. Consider the SOT-665 package size constraints and operating temperature range of -40°C to +85°C for final design validation.
Part Context
This part belongs to the IP4256 series of dual-channel EMI filters. It is distinct from single-channel variants or other packages within the same family. The device serves as an integrated solution for protecting sensitive downstream components from both electromagnetic noise and electrostatic discharge events in portable communication devices.
Replacement Considerations
Check for direct substitutes within the IP4256 series that may offer different packaging options or updated lifecycle statuses. Verify pinout compatibility if considering alternative manufacturers. Consult Nexperia's official substitution guide for validated replacements.
