Dual-channel passive filter network with ESD protection

The IP4256CZ5-W is a dual-channel RC low-pass filter which provides high-level ElectroStatic Discharge (ESD) protection.

The device is designed to protect a range of portable communication transmitter applications against unwanted RF signals. Incorporated diodes provide protection to downstream components from ESD voltages up to ±25 kV contact discharge, far exceeding IEC 61000-4-2 level 4.

The device is manufactured using monolithic silicon technology.

Not recommended for new automotive design-ins.

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
