Product details
Overview
PESD4USB3UBTBS-QJ from Nexperia is a unidirectional ESD protection diode array in DFN2510D-10 (SOT1176D) package, designed for high-speed serial interfaces including USB 3.2 Gen 1, HDMI 2.1, DisplayPort, eSATA, LVDS, and GMSL SerDes. It delivers 3.3 V reverse standoff voltage, 0.4 pF typical line capacitance, and ±15 kV IEC 61000-4-2 contact discharge protection.
For engineers reviewing the PESD4USB3UBTBS-QJ datasheet, PESD4USB3UBTBS-QJ pinout, PESD4USB3UBTBS-QJ application, or PESD4USB3UBTBS-QJ equivalent, key selection criteria include ultra-low capacitance for signal integrity, AEC-Q101 qualification for automotive use, matched 0.5 mm trace spacing for AOI compatibility, and snap-back clamping with 0.2 Ω dynamic resistance.
Technical Context
This device implements a deep snap-back clamping structure to reduce clamping voltage during ESD transients, achieving 3 V clamping at 6.5 A (8/20 µs) while maintaining sub-0.5 pF capacitance across all four protected channels. Its negative dynamic resistance behavior enables low-voltage clamping without sacrificing high-speed signal fidelity.
Designed for system-level protection of differential high-speed buses, it supports bidirectional data flow on each channel via unidirectional diode configuration referenced to ground, with two dedicated GND pins (pins 3 and 8) for low-inductance return paths and minimized ground bounce.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V reverse standoff voltage - ensures no leakage or conduction during normal 3.3 V interface operation |
| Cd | 0.4 pF typical capacitance at 1 MHz - preserves signal integrity on >5 Gbps links like USB 3.2 and HDMI 2.1 |
| VCL | 3 V clamping voltage at 6.5 A (8/20 µs) - limits transient overvoltage to safe levels for downstream PHYs |
| Rdyn | 0.2 Ω dynamic resistance - enables rapid energy shunting with minimal voltage overshoot during ESD events |
| ESD Rating | ±15 kV IEC 61000-4-2 contact discharge - exceeds Level 4 immunity for automotive and industrial environments |
| Breakdown Voltage | 5.5–11.5 V (VBR at 1 mA) - provides margin above VRWM while enabling robust snap-back initiation |
| Leakage Current | 1 nA typical IRM at 3.3 V - prevents DC loading or bias shift on high-impedance data lines |
Pinout & Package
DFN2510D-10 (SOT1176D) is a leadless, side-wettable flank (SWF), 10-terminal plastic package measuring 2.5 mm × 1.0 mm × 0.75 mm with 0.5 mm pitch. Its compact footprint and AOI-compatible flanks support automated optical inspection and high-yield reflow soldering in space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection anode for first high-speed data line (e.g., USB 3.2 TX+/RX+) |
| 2 | CH2 | ESD protection anode for second high-speed data line (e.g., USB 3.2 TX−/RX−) |
| 3 | GND | Dedicated low-inductance ground return path for CH1 and CH2 |
| 4 | CH3 | ESD protection anode for third high-speed data line (e.g., HDMI TMDS0+) |
| 5 | CH4 | ESD protection anode for fourth high-speed data line (e.g., HDMI TMDS0−) |
| 6, 7, 9, 10 | n.c. | No internal connection - electrically isolated; must remain unconnected on PCB |
| 8 | GND | Second dedicated ground terminal for CH3 and CH4, enabling split-ground routing |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.4 pF per channel - maintains impedance continuity and minimizes insertion loss up to 10 GHz |
| Snap-back clamping | 0.2 Ω dynamic resistance - reduces clamping voltage by >40% versus standard TVS diodes under 6.5 A stress |
| Side-wettable flanks | SWF-enabled DFN2510D-10 package - allows reliable AOI inspection of solder joints without X-ray |
| AEC-Q101 qualification | Qualified for automotive applications - validated for temperature cycling, HTRB, and ESD robustness per AEC standard |
| Pass-through routing | Linear pin arrangement (1–5, then 8) - supports straight-through PCB trace layout without vias or bends |
Applications
| Infotainment USB/HDMI Interfaces | Automotive Display Video Links |
|---|---|
|
Use Scenario: Protecting USB 3.2 Gen 1 and HDMI 2.1 data lanes in vehicle head units and central displays. IC Role / Device Role / Timing Role: Unidirectional ESD clamp placed directly at connector entry point to shunt transients before reaching SerDes PHY.

|
Use Scenario: Securing external SATA and LVDS links in infotainment storage subsystems and rear-seat entertainment systems. IC Role / Device Role / Timing Role: Standoff-rated (3.3 V) unidirectional diode array placed inline with differential signal traces near board edge connectors. Use Value: 1 nA max leakage prevents DC bias shift on high-impedance LVDS receivers; 0.5 mm trace spacing matches standard PCB routing rules. |
Use Scenario: Hardening DisplayPort and APIX 2/3 links in digital instrument clusters and HUD projection systems. IC Role / Device Role / Timing Role: System-level ESD suppressor integrated into high-density flex-rigid PCBs where space and signal integrity are critical. Use Value: DFN2510D-10 footprint (2.5 × 1.0 mm) saves >60% area versus SO-8 alternatives; SWF design enables full solder-joint visibility. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DPYR | 0.5 pF capacitance, 3.6 V VRWM, single-channel SC-70 package | Requires four discrete devices for quad-channel protection; lacks AEC-Q101 qualification | Select when board space permits discrete placement and automotive qualification is not required |
| ESD5451N-2/TR | 0.35 pF capacitance, 3.3 V VRWM, DFN1006-2 package per channel | Four separate 2-pin devices needed; no integrated dual-GND or pass-through routing support | Choose only if lowest possible capacitance is prioritized over layout simplicity and automotive compliance |
Compared with TPD4E001DPYR and ESD5451N-2/TR, PESD4USB3UBTBS-QJ delivers integrated quad-channel protection in one AEC-Q101-qualified package with optimized routing, dual GND terminals, and verified 0.2 Ω dynamic resistance-reducing BOM count, PCB area, and ground-loop risk in automotive high-speed designs.

FAQ
What is the maximum operating temperature range for PESD4USB3UBTBS-QJ?
The device is rated for ambient temperatures from −55 °C to +150 °C and storage temperatures from −65 °C to +150 °C, fully supporting under-hood and display-module thermal environments in automotive applications per AEC-Q101 requirements.
Does PESD4USB3UBTBS-QJ require external biasing or control signals?
No. It operates passively as a clamping diode array with no external power, enable, or configuration pins. Protection activates automatically when transient voltage exceeds the 5.5–11.5 V breakdown threshold, with no firmware or circuitry overhead.
Can PESD4USB3UBTBS-QJ be used on bidirectional differential interfaces like USB 3.2?
Yes. Though unidirectional per channel, its anode-to-ground configuration protects both polarities of differential signals when paired across complementary lines (e.g., CH1 on TX+, CH2 on TX−), maintaining signal symmetry and common-mode rejection.
How does the snap-back behavior affect system reliability during repeated ESD events?
The snap-back structure reduces clamping voltage dynamically but requires proper PCB layout: avoid connecting protected lines to unlimited DC current sources, as sustained overvoltage could hold the device in snap-back state and increase power dissipation beyond safe limits.
