ESD protection
Rev. 1 — 23 July 2010
Product data sheet
1. Product profile
1.1 General description
The IP4256CZ3-M is a single-channel low-pass filter while the IP4256CZ5-W and
IP4256CZ6-F are dual-channel RC low-pass filters. All devices provide high-level
ElectroStatic Discharge (ESD) protection.
The devices are designed to protect a range of portable communication transmitter
applications against unwanted RF signals. The devices incorporate diodes to provide
protection to downstream components from ESD voltages up to ±25 kV contact discharge
far exceeding IEC 61000-4-2, level 4.
The devices are manufactured using monolithic silicon technology in lead-free plastic
packages.
