NXP IP4220CZ6

IP4220CZ6 概要

IP4220CZ6 is a versatile ESD protection device designed to enhance the reliability and durability of electronic equipment in various applications where ESD events can potentially cause damage or signal disruption.

特徴

RoHS Compliant: The IP4220CZ6 is compliant with the Restriction of Hazardous Substances (RoHS) directive, which restricts the use of certain hazardous substances in electronics manufacturing. It is also free of halogen and antimony, which is often referred to as "Dark Green" compliance.

ESD Protection: The device provides robust ESD (ElectroStatic Discharge) protection of up to ±8 kV during contact discharge, complying with the IEC 61000-4-2 standard at level 4. This level of protection is crucial for preventing damage to sensitive electronic components.

Ultra-Low Input Capacitance: The IP4220CZ6 features four pairs of ultra-low input capacitance (CI = 1 pF) ESD rail-to-rail protection diodes. Low input capacitance is essential for applications involving high-frequency analog signal ports and high-speed data transmission because it minimizes signal distortion.

Zener Diode: The device includes an integrated Zener diode, which ensures low voltage clamping during ESD events. This diode helps limit the voltage across protected components, preventing them from exceeding safe voltage levels.

Small SMD Package: The IP4220CZ6 is packaged in a compact 6-lead TSOP6 (SOT457) Surface-Mounted Device (SMD) package. This small form factor makes it suitable for space-constrained electronic designs and allows for easy integration onto circuit boards.

応用

The IP4220CZ6 is designed for general-purpose ESD protection in a range of applications, particularly those involving high-frequency analog signal ports and high-speed serial data transmission. Some specific applications include:

Cellular Phones and PCS Mobile Handsets: Protects various ports and connectors in mobile phones, ensuring their reliability and longevity.

PC and Notebook USB 2.0/IEEE1394 Ports: Safeguards USB and IEEE1394 (FireWire) ports on computers and laptops from ESD damage.

DVI (Digital Video Interface): Provides ESD protection for DVI interfaces used in displays and video equipment.

Cordless Telephones: Protects connectors and ports in cordless telephone systems, preventing ESD-related issues.

Wireless Data Systems (WAN/LAN): Ensures the reliability of connectors and ports in wireless data communication systems.

Mobile Internet Devices (MID): Protects MID interfaces, allowing them to withstand ESD events.

Portable Media Players (PMP): Provides ESD protection for the ports and connectors of portable media players.

High-Definition Multimedia Interface (HDMI): Safeguards HDMI ports used in high-definition multimedia devices.
