Product details
Overview
IP4234CZ6 from Nexperia is a single-channel USB 2.0 ESD protection device in a 6-lead SOT457 (TSOP6) package, featuring dual π-filter ESD diodes with rail-to-rail architecture and an integrated Zener diode for supply-independent clamping. It delivers ±8 kV IEC 61000-4-2 level 4 contact discharge protection, 3.1 pF typical I/O-to-ground capacitance, and 0.5 Ω series resistance-optimized for high-speed signal integrity on USB D+/D− and VBUS lines in portable electronics.
For engineers reviewing the IP4234CZ6 datasheet, IP4234CZ6 pinout, IP4234CZ6 application, or IP4234CZ6 equivalent, key selection criteria include low-capacitance ESD protection for 480 Mbps USB 2.0 data paths, simultaneous VBUS and differential signal line protection, rail-to-rail clamping independent of supply voltage, and compliance with IEC 61000-4-5 (15 A lightning surge).
Technical Context
The IP4234CZ6 implements a monolithic π-filter structure per channel: two ultra-low-capacitance ESD diodes (pins 1/3 and 4/6) connected to ground via internal series resistors (0.5 Ω), plus a dedicated Zener diode (pin 5 to pin 2) for low-voltage clamping of VBUS. Its rail-to-rail diode architecture ensures ESD protection remains effective across 0 V to 5.5 V supply range without dependency on external bias.
It supports bidirectional ESD suppression on two independent I/O channels (each with matched 3.1 pF CI/O-GND) while maintaining signal integrity for USB 2.0's 480 Mbps data rate. The device meets IEC 61000-4-5 Level 3 (15 A, 8/20 μs) lightning surge immunity and operates continuously from −40 °C to +85 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±8 kV contact discharge per IEC 61000-4-2 level 4 - guarantees robust protection against common human-body model events in handheld devices. |
| I/O Capacitance | 3.1 pF typical (pins 1,3,4,6 to GND at 1 MHz) - preserves USB 2.0 signal rise/fall times and minimizes bit error rate. |
| Zener Breakdown | 6–9 V (pin 5 to pin 2 at 1 mA) - provides precise VBUS overvoltage clamping without interfering with 5 V nominal operation. |
| Series Resistance | 0.5 Ω typical - limits ESD current peak while maintaining low insertion loss on high-speed data lines. |
| Lightning Surge | 100 W peak pulse power (8/20 μs, 15 A) per IEC 61000-4-5 - withstands induced surges in docking stations and peripheral hubs. |
| Operating Temp | −40 °C to +85 °C - supports deployment in consumer mobile handsets and industrial USB host interfaces. |
Pinout & Package
IP4234CZ6 is housed in a miniature 6-lead SOT457 (TSOP6) surface-mount package measuring 3.1 mm × 2.7 mm × 1.1 mm, optimized for space-constrained USB port layouts on PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | ESD protection I/O channel 1 anode | Connects to USB D+ or D− signal line; forms first diode junction in π-filter path to ground. |
| 2 | Ground (GND) | Common reference for all ESD diodes and Zener cathode; must be low-inductance PCB connection. |
| 3 | ESD protection I/O channel 1 cathode | Completes π-filter path for channel 1; ties to same signal line as pin 1 via internal resistor. |
| 4 | ESD protection I/O channel 2 anode | Connects to second USB signal line (e.g., D− if pin 1 is D+) or VBUS; independent protection path. |
| 5 | Supply voltage (VBUS) | Zener diode anode input; clamps VBUS transients to 6–9 V during ESD events. |
| 6 | ESD protection I/O channel 2 cathode | Completes π-filter path for channel 2; matches pin 3 functionality for second protected line. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail ESD diode architecture | Enables full-swing protection from −0.5 V to +5.5 V without external bias, eliminating need for VCC-dependent clamp circuits. |
| Ultra-low 3.1 pF I/O capacitance | Preserves USB 2.0 eye diagram integrity at 480 Mbps by minimizing signal attenuation and jitter accumulation. |
| Dual-channel π-filter topology | Provides independent, matched ESD protection for both differential data lines (D+/D−) and VBUS using one monolithic die. |
| Integrated Zener diode on VBUS pin | Clamps supply-line transients to ≤9 V before downstream regulators, preventing brownout or latch-up in USB power switches. |
| SOT457 (TSOP6) package | Enables direct placement adjacent to USB connectors with minimal trace length, reducing parasitic inductance in ESD current path. |
Applications
| USB 2.0 Mobile Handset Interface | PC Notebook USB Port Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 2.0 ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Single-channel, 4-pin SOT-23; 12 pF I/O capacitance; no integrated VBUS Zener. | Limited to one data line; requires external clamping for VBUS; higher capacitance risks USB 2.0 eye closure. | Select only when board space permits separate VBUS protection and lower-cost single-line coverage suffices. |
| Vishay VEML6030X01 | Optical sensor IC-not an ESD protector; incompatible function and pinout. | Not applicable; misidentified part with no ESD protection capability. | Avoid-this is not a functional alternative; verify part number before sourcing. |
Compared with NUP4201MR6T1G, IP4234CZ6 delivers 74% lower I/O capacitance and integrated VBUS clamping in the same footprint, enabling true single-chip USB 2.0 port hardening; VEML6030X01 is non-functional as ESD protection and must be excluded from selection.

FAQ
What is the maximum continuous operating voltage on the VBUS pin (pin 5)?
The IP4234CZ6 supports a maximum input voltage of +5.5 V on pin 5 under normal operation, with absolute maximum rating of +5.5 V (VI). This aligns with standard USB 2.0 VBUS specification and ensures compatibility with 5 V tolerant transceivers without derating.
Can IP4234CZ6 protect both USB data lines and VBUS simultaneously?
Yes-pins 1/3 protect one signal line (e.g., D+), pins 4/6 protect the second (e.g., D−), and pin 5 (VBUS) connects to the integrated Zener diode for independent 6–9 V clamping. All three functions operate concurrently without interaction or performance trade-off.
Is the 3.1 pF capacitance measured at DC or AC bias?
The 3.1 pF typical I/O-to-ground capacitance is measured at VI = 0 V, f = 1 MHz, and VCC = 3.0 V, per Table 5 of the datasheet. It remains stable across 0–5.5 V bias due to the rail-to-rail diode architecture and absence of voltage-dependent depletion regions.
Does IP4234CZ6 require external decoupling capacitors?
No external decoupling is required-the device integrates all necessary filtering elements (π-filter resistors and diodes) internally. Layout best practice is to place it within 3 mm of the USB connector with direct GND pour and minimized trace inductance to ground pin 2.
