NXP Semiconductors IP4284CZ10-TB,115

Overview

IP4284CZ10-TB from NXP Semiconductors is a 4-channel ESD protection diode array designed for ultra-high-speed differential interfaces including HDMI 1.3/1.4, DisplayPort, USB SuperSpeed 3.0, eSATA, and LVDS. It delivers ±8 kV contact ESD protection per IEC 61000-4-2 Level 4, features 0.5 pF typical channel capacitance, and uses rail-to-rail clamping diodes in an XSON10U (SOT1059-1) package measuring 1 × 2.5 × 0.5 mm - deployed in TV HDMI receiver ports to preserve signal integrity at 5 Gbit/s.

For engineers reviewing the IP4284CZ10-TB datasheet, IP4284CZ10-TB pinout, IP4284CZ10-TB application, or IP4284CZ10-TB equivalent, key selection criteria include sub-0.7 pF max TMDS channel capacitance, matched ≤0.05 pF inter-pair capacitance difference, dual ground pins for low-inductance return paths, and compatibility with 100 Ω differential impedance routing for HDMI/DisplayPort layouts.

Technical Context

This device implements integrated bidirectional Zener diodes on all four signal channels (CH1–CH4), each with 6–9 V breakdown voltage and ≤1 μA reverse leakage at 3.0 V bias. Clamping occurs via low-dynamic-resistance (≤1 Ω) transient response during ±8 kV ESD events, enabling robust downstream protection without signal distortion.

The XSON10U package supports pass-thru PCB routing with 0.5 mm trace spacing alignment and maintains mutual channel capacitance ≤0.07 pF - critical for minimizing NEXT crosstalk in tightly spaced HDMI TMDS pairs operating up to 5 Gbit/s, as verified by eye diagram testing with CP0 pattern compliance.

FAQ

What is the maximum operating voltage supported by IP4284CZ10-TB?

IP4284CZ10-TB supports an input voltage range of −0.5 V to +5.5 V per pin, making it compatible with 3.3 V and 5 V logic interfaces including HDMI, DisplayPort, and eSATA. Its Zener breakdown voltage of 6–9 V ensures safe clamping above normal signal swings without forward conduction during steady-state operation - a key design feature confirmed in Table 4 of the official NXP datasheet.

Does IP4284CZ10-TB require external biasing or power supply connections?

No, IP4284CZ10-TB operates without external bias or power supply - its rail-to-rail clamping diodes connect directly between signal lines and ground (pins 3 and 8), requiring only proper PCB grounding. This passive architecture eliminates quiescent current draw and simplifies layout, as validated by the "no VCC pin" configuration in the pinning table and application diagrams in Figures 10 and 11 of the NXP datasheet.

Can IP4284CZ10-TB be used for USB 3.0 SuperSpeed differential pairs?

Yes, IP4284CZ10-TB is explicitly qualified for USB 3.0 SuperSpeed (5 Gbit/s) protection, with 0.5 pF typical channel capacitance and ≤0.05 pF inter-pair matching ensuring minimal eye diagram degradation. Figure 4 in the NXP datasheet confirms clean CP0-pattern eye diagrams using IP4284CZ10-TB on reference PCBs - confirming its suitability for SSTX+/SSTX− and SSRX+/SSRX− lanes.

How does the XSON10U package of IP4284CZ10-TB support high-speed layout?

The XSON10U package of IP4284CZ10-TB enables high-speed layout via linear pin sequencing (CH1–CH2–GND–CH3–CH4–n.c.–n.c.–GND–n.c.–n.c.), allowing straight-through trace routing with no vias or stubs. Its 1 × 2.5 × 0.5 mm body and 0.5 mm trace spacing alignment reduce parasitic inductance and maintain 100 Ω differential impedance - a design advantage documented in Section 1.2 and Figure 12 of the NXP datasheet.

Is IP4284CZ10-TB RoHS compliant and halogen-free?

Yes, IP4284CZ10-TB is Pb-free, RoHS compliant, and fully halogen- and antimony-free - certified as "Dark Green compliant" per NXP's environmental policy. This compliance is stated in Section 1.2 "Features and benefits" and verified through material declarations aligned with JEDEC J-STD-609A standards, ensuring suitability for global consumer electronics markets.
