Product details
Overview
PUSB3FR4 from Nexperia is a 4-channel ultra-low-capacitance ESD protection diode array designed for SuperSpeed USB 3.2 (10 Gbps), HDMI, DisplayPort, eSATA, and LVDS interfaces. It provides ±15 kV IEC 61000-4-2 contact ESD protection per channel with 0.29 pF typical line capacitance, 0.27 Ω dynamic resistance, and snapback clamping down to 1.5 V at 1 A.
For engineers reviewing the PUSB3FR4 datasheet, PUSB3FR4 pinout, PUSB3FR4 application, or PUSB3FR4 equivalent, this device is selected for high-speed serial interface protection where signal integrity, impedance matching, and sub-0.3 pF channel capacitance are critical - especially in compact mobile and display port designs requiring robust system-level ESD immunity without degrading eye diagrams.
Technical Context
The PUSB3FR4 implements four independent rail-to-rail snapback diode structures optimized for differential high-speed data lanes. Each channel delivers bidirectional clamping with breakdown voltage ≥5.5 V and clamping voltage ≤±3 V at ±5 A (IEC 61000-4-5).
Its DFN2510A-10 package enables matched 0.5 mm trace spacing and ≤0.05 pF inter-pair capacitance matching, preserving differential impedance and minimizing NEXT crosstalk - validated via TLP testing, eye diagram analysis (USB 3.2 and HDMI 2.0), and TDR measurements showing <10% impedance deviation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Line capacitance | 0.29 pF typical per channel - preserves signal integrity up to 10 Gbps without measurable eye closure. |
| ESD rating | ±15 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds industrial system-level immunity requirements. |
| Dynamic resistance | 0.27 Ω typical - minimizes voltage overshoot during fast ESD transients, reducing stress on downstream PHYs. |
| Snapback voltage | 1.5 V at 1 A TLP - enables low-clamp protection that avoids false triggering or latch-up in 3.3 V systems. |
| Breakdown voltage | 5.5 V minimum - ensures safe operation above 3.3 V supply rails while maintaining margin against overvoltage. |
| Capacitance matching | ≤0.05 pF difference between differential pairs - maintains common-mode rejection and reduces skew in HDMI/DP links. |
Pinout & Package
Encapsulated in a leadless DFN2510A-10 (SOT1176-1) package: 2.5 mm × 1.0 mm × 0.5 mm body, 0.5 mm pitch, 10-terminal layout with dual ground pins and four protected channels.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD-protected input/output for first differential pair (e.g., USB3 TX+/TX−) |
| 2 | CH2 | ESD-protected input/output for second differential pair (e.g., USB3 RX+/RX−) |
| 3 | GND | Primary ground reference for CH1–CH2 clamping path; low-inductance return |
| 4 | CH3 | ESD-protected input/output for third differential pair (e.g., HDMI TMDS0+/−) |
| 5 | CH4 | ESD-protected input/output for fourth differential pair (e.g., HDMI TMDS1+/−) |
| 6, 7, 9, 10 | n.c. | No internal connection - electrically isolated; must remain unconnected on PCB |
| 8 | GND | Secondary ground reference for CH3–CH4 clamping path; improves symmetry and thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance architecture | 0.29 pF/channel enables full compliance with USB 3.2 Gen 2 (10 Gbps) and HDMI 2.0 eye mask requirements. |
| Matched differential pair layout | 0.5 mm trace spacing + ≤0.05 pF capacitance mismatch ensures <0.1 dB insertion loss imbalance up to 5 GHz. |
| Deep snapback clamping | 1.5 V snapback voltage at 1 A prevents overvoltage damage to 3.3 V SerDes receivers during ESD events. |
| Rail-to-rail bidirectional protection | Clamps both positive and negative transients to VDD and GND - no external bias required for USB/HDMI hot-plug scenarios. |
| Pass-through signal routing | Linear pin arrangement (CH1–CH2–GND–CH3–CH4) supports direct in-line PCB trace routing without vias or bends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESD7L5.0DT5G | Single-channel, 0.55 pF capacitance, ±12 kV ESD rating | Limited to lower-speed interfaces (≤3 Gbps); requires 4× placement for quad-lane protection | Use only when board space allows discrete placement and speed requirements are ≤USB 2.0. |
| Texas Instruments TPD4E05U06DQAR | 4-channel, 0.5 pF capacitance, ±12 kV ESD rating, integrated VBUS switch control | Higher capacitance degrades 10 Gbps eye opening; includes auxiliary logic not needed for passive protection | Select only if VBUS switching functionality is required - otherwise PUSB3FR4 offers superior RF performance. |
Compared with ESD7L5.0DT5G and TPD4E05U06DQAR, the PUSB3FR4 delivers 2.3× lower line capacitance and 25% higher ESD rating in a single compact package - making it uniquely suited for 10 Gbps differential interfaces where signal fidelity and system-level immunity must coexist.

FAQ
Does PUSB3FR4 require external bias or power supply?
No. The PUSB3FR4 is a passive, rail-to-rail ESD protection device with no VCC or control pins. It operates solely through its internal snapback diode structure, clamping transients between signal lines and ground or supply rails without external bias - ideal for hot-plug interfaces like USB-C and HDMI.
Can PUSB3FR4 be used on single-ended interfaces like USB 2.0 D+ and D−?
Yes. Although optimized for differential signals, its 0.29 pF capacitance and ±15 kV ESD rating make it fully compatible with USB 2.0 full-speed/high-speed D+/D− lines. Pin assignments remain identical: CH1 and CH2 protect one differential pair, with GND pins providing low-inductance return paths.
What is the maximum recommended trace length between PUSB3FR4 and protected IC?
For optimal ESD performance, keep trace lengths from the protected IC's I/O pad to the PUSB3FR4 pins under 3 mm. Longer traces increase inductance, raising clamping voltage during fast ESD events - verified by TLP testing showing <1.5 V snapback only with minimal loop area and direct GND stitching.
Is PUSB3FR4 compliant with RoHS and REACH regulations?
Yes. The PUSB3FR4 is manufactured in accordance with Nexperia's standard environmental compliance program: lead-free (Pb-free), halogen-free, RoHS Directive 2011/65/EU compliant, and REACH SVHC-free - confirmed in the official product declaration available on Nexperia's website.
