Product details
Overview
IP4233CZ6 from Nexperia is an ultra-low-capacitance ESD protection diode array designed for high-frequency AC-coupled Ethernet I/O ports, delivering ±8 kV IEC 61000-4-2 contact discharge protection, 0.9 pF typical input-to-ground capacitance, and back-to-back diode configuration to prevent negative signal clipping in 10/100BASE-T transceivers.
For engineers reviewing the IP4233CZ6 datasheet, IP4233CZ6 pinout, IP4233CZ6 application, or IP4233CZ6 equivalent, key selection criteria include low signal distortion (sub-1 pF capacitance), dual-channel differential protection capability, compatibility with Ethernet PHY voltage rails, and SOT363 footprint constraints for dense PCB layouts.
Technical Context
The IP4233CZ6 integrates two monolithic silicon back-to-back diode pairs-each pair spanning pins 2–6 and 3–5-to provide symmetrical clamping for bidirectional AC signals without DC bias shift. Its architecture avoids forward conduction during normal operation while enabling rapid avalanche response to transient ESD events.
Designed specifically for Ethernet physical layer interfaces, it operates within −40 °C to +85 °C ambient range, supports ±5.5 V maximum input voltage, and maintains reverse leakage below 100 nA at 3.0 V, ensuring minimal loading on high-impedance transceiver lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±8 kV contact discharge per IEC 61000-4-2 Level 4 - ensures robust immunity against common handling and system-level ESD events |
| Capacitance (I/O–GND) | 0.9 pF typical at 1 MHz - preserves signal integrity in 10/100 Mbit/s Ethernet channels by minimizing rise-time degradation |
| Breakdown Voltage (VBR) | 6–9.5 V at 5 mA - sets clamping threshold above Ethernet common-mode voltage but below PHY absolute maximum ratings |
| Reverse Leakage (IRM) | ≤100 nA at 3.0 V - prevents DC loading of AC-coupled PHY inputs and avoids baseline shift in differential receivers |
| Operating Temperature | −40 °C to +85 °C - supports industrial-grade Ethernet equipment deployment without derating |
| Package | SOT363 (SC-88) - 2.2 mm × 1.8 mm footprint enables placement adjacent to RJ45 magnetics or PHY ICs |
Pinout & Package
The IP4233CZ6 is housed in a plastic surface-mounted SOT363 (SC-88) package with 6 leads, optimized for space-constrained Ethernet port layouts. Pin 1 is index-marked; pins 1 and 4 are not connected and must remain unpopulated or floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Unbonded die pad - must be left unconnected to avoid parasitic coupling or solder bridging |
| 2 | I/O Channel 1 Anode | Input terminal for first back-to-back diode pair; connects to TX+/RX+ line in Ethernet PHY interface |
| 3 | I/O Channel 2 Anode | Input terminal for second back-to-back diode pair; connects to TX−/RX− line in Ethernet PHY interface |
| 4 | No Connect (NC) | Unbonded die pad - electrically isolated and thermally inactive |
| 5 | I/O Channel 2 Cathode | Return path for second diode pair; ties to GND plane via shortest possible trace to minimize inductance |
| 6 | I/O Channel 1 Cathode | Return path for first diode pair; shares GND connection with pin 5 for matched clamping symmetry |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.9 pF typical - enables use in 100BASE-TX without measurable jitter or eye closure |
| Back-to-back diode topology | Dual anti-series configuration - blocks DC current flow while clamping both positive and negative ESD transients |
| RoHS-compliant packaging | Pb-free SOT363 construction - meets EU Directive 2011/65/EU and supports lead-free reflow assembly |
| Monolithic silicon integration | Single-die dual-channel design - eliminates inter-device timing skew and ensures matched clamping characteristics |
Applications
| 10/100BASE-T Ethernet PHY Protection | Industrial Ethernet Switch Ports |
|---|---|
Use Scenario: Protecting differential TX+/TX− and RX+/RX− lines of a single-port 10/100 Mbit/s Ethernet transceiver before magnetics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 0.8 pF capacitance, ±8 kV ESD rating, but uses single-diode + TVS architecture instead of back-to-back pairs | Lacks inherent AC-signal symmetry; requires external bias network for true bidirectional clamping | Prefer IP4233CZ6 when protecting inherently AC-coupled lines without DC bias paths |
| SP3012-02UTG | 0.3 pF capacitance, ±12 kV ESD rating, but rated only to 3.3 V working voltage vs. ±5.5 V for IP4233CZ6 | Not suitable for mixed-voltage Ethernet PHYs or legacy 5 V tolerant interfaces | Select IP4233CZ6 for designs requiring higher voltage margin and proven Ethernet interoperability |
Compared with TPD2E001DRYR and SP3012-02UTG, the IP4233CZ6 uniquely combines sub-1 pF capacitance, ±5.5 V operating range, and native back-to-back topology-making it the only option qualified for direct placement on 10/100BASE-T differential pairs without signal conditioning.

FAQ
What is the maximum recommended trace length between IP4233CZ6 and the Ethernet PHY IC?
Trace length from IP4233CZ6 pins 2/3 to the PHY I/O pins should not exceed 3 mm to maintain sub-nanosecond clamping response and minimize inductive overshoot. Longer traces increase peak voltage seen by the PHY during ESD events due to L·di/dt effects, potentially exceeding the ±5.5 V absolute maximum rating.
Can IP4233CZ6 be used for 1000BASE-T (Gigabit Ethernet) applications?
No-IP4233CZ6 is characterized and validated only for 10/100BASE-T operation. Its 0.9 pF capacitance introduces unacceptable insertion loss and return loss degradation above 62.5 MHz, and its clamping dynamics are not specified for the 125 MHz symbol rate of Gigabit Ethernet.
Is thermal pad grounding required for IP4233CZ6 in SOT363 package?
No thermal pad is present in the SOT363 package; the device relies on PCB copper area under pins 5 and 6 for heat dissipation. A minimum 10 mm² GND pour connected directly to pins 5 and 6 via multiple 0.3 mm vias is recommended to sustain repetitive ESD pulses without junction temperature exceedance.
Does IP4233CZ6 require external decoupling capacitors?
No external decoupling is needed-the device has no power supply pins and operates passively. However, a 100 nF ceramic capacitor should be placed between the local GND pour (connected to pins 5/6) and system GND to stabilize the reference during multi-pulse ESD events and reduce ground bounce.
