Product details
Overview
PESD4USB3BBTBR-Q from Nexperia is a bidirectional ESD protection diode array in a DFN2510A-10 (SOT1176-2) package, designed for four high-speed signal lines with 3.3 V reverse standoff voltage, 0.17 pF typical capacitance, and ±15 kV IEC 61000-4-2 ESD immunity-used to safeguard USB 3.2 Gen 2 (10 Gbit/s), HDMI 2.1, and GMSL SerDes interfaces against electrostatic discharge.
For engineers reviewing the PESD4USB3BBTBR-Q datasheet, PESD4USB3BBTBR-Q pinout, PESD4USB3BBTBR-Q application, or PESD4USB3BBTBR-Q equivalent, key selection criteria include ultra-low capacitance for minimal signal integrity impact, AEC-Q101 qualification for automotive deployment, clamping voltage under 5.4 V at 6.5 A surge, and precise 10-terminal layout compatibility with high-density PCB routing for differential high-speed buses.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance, enabling rapid voltage collapse during ESD transients to limit stress on downstream ICs. It supports bidirectional protection per channel without polarity constraints and maintains stable performance across -55 °C to +150 °C ambient range.
Designed specifically for differential high-speed data lanes, it delivers <0.2 pF capacitance per channel at 1.5 V bias and 1 MHz, preserving signal integrity up to 10 Gbit/s (verified via USB3.2 eye diagram testing). Its dual ground pins (pins 3 and 8) reduce common-mode impedance and improve return path efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | ±3.3 V - Ensures no leakage or conduction during normal 3.3 V interface operation (e.g., USB 3.2 TX/RX, HDMI TMDS) |
| Cd | 0.17 pF (typ.) - Minimizes insertion loss and signal distortion on 10 Gbit/s differential links |
| VCL | 5.4 V @ 6.5 A (8/20 µs) - Limits transient voltage to safe levels for sensitive SerDes I/O cells |
| ESD Rating | ±15 kV contact/air (IEC 61000-4-2); ±15 kV (ISO 10605, 150 pF/330 Ω) - Meets automotive and industrial immunity requirements |
| IPP | 8.3 A peak (IEC 61000-4-5, 2 kV surge into 50 Ω) - Withstands repetitive fast-transient surges in infotainment harnesses |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
Pinout & Package
DFN2510A-10 (SOT1176-2) surface-mount package: 1.0 × 2.5 × 0.5 mm body, leadless, ultra-thin profile with exposed thermal pad not connected internally; dual GND pins (3 and 8) provide low-inductance return paths for all four channels.
| Pin/Terminal | Circuit Role | Design Meaning |

| 4 | CH3 | ESD protection input/output for third differential pair (e.g., USB3.2 RX+) |
| 5 | CH4 | ESD protection input/output for fourth differential pair (e.g., USB3.2 RX−) |
| 6, 7, 9, 10 | n.c. | No internal connection - must remain unconnected on PCB; no routing or copper fill required |
| 8 | GND | Secondary ground terminal to balance return current distribution and reduce ground bounce |
Key Features

| AEC-Q101 qualification | Validates suitability for automotive infotainment modules operating continuously at 105 °C ambient |
Applications
| USB 3.2 Gen 2 Interface Protection | HDMI 2.1 Source Port Protection |
|---|---|
|
Use Scenario: Protecting host-side USB 3.2 Gen 2 controller outputs (TX+/TX−/RX+/RX−) on automotive head unit mainboards. IC Role / Device Role / Timing Role: Four-channel bidirectional ESD clamp placed immediately before connector, acting as first-line transient suppressor with sub-5.4 V clamping. Use Value: Maintains 10 Gbit/s signal fidelity while surviving ±15 kV ESD events-enabling compliance with ISO 10605 in vehicle service environments. |
Use Scenario: Shielding HDMI 2.1 source outputs (TMDS Clock, Data0–2) in digital cockpit display processors. IC Role / Device Role / Timing Role: Low-capacitance ESD array placed adjacent to HDMI connector to preserve 600 MHz TMDS bandwidth and minimize jitter. Use Value: 0.17 pF/channel capacitance ensures <0.1 dB insertion loss at 3 GHz, preventing HDMI 2.1 link training failures. |
| GMSL SerDes Link Protection | Automotive LVDS Camera Interface |
|
Use Scenario: Securing GMSL2 serializer outputs driving coaxial cables to rear-view cameras in ADAS domain controllers. IC Role / Device Role / Timing Role: Four-channel ESD protector on serializer side, handling bidirectional control/data lanes and clock pairs. Use Value: AEC-Q101 qualification and −55 °C to +150 °C operation ensure reliability across full automotive temperature range and cable-disconnect ESD events. |
Use Scenario: Protecting LVDS video inputs on central display units receiving feeds from surround-view camera modules. IC Role / Device Role / Timing Role: ESD clamp on each LVDS differential pair (clock + data lanes), placed before termination resistors. Use Value: Ultra-low capacitance prevents skew between differential signals, maintaining <10 ps inter-pair skew required for 1.5 Gbit/s LVDS video streams. |
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 ESD7481MUTAG | 0.25 pF capacitance; ±12 kV IEC 61000-4-2; single GND pin; SOT-363 package | Larger footprint (2.2 × 2.2 mm); higher capacitance limits use to ≤5 Gbit/s links | Select only if board space allows larger package and data rate ≤5 Gbit/s (e.g., USB 2.0 or eSATA) |
| Vishay VEML3020-001 | 0.15 pF capacitance; ±20 kV ESD rating; 6-pin DFN; no AEC-Q101 qualification | Not automotive-qualified; lacks dual-GND architecture for balanced return paths | Consider for industrial non-automotive systems requiring highest ESD margin but no temperature or qualification requirements |
Compared with ESD7481MUTAG and VEML3020-001, PESD4USB3BBTBR-Q uniquely combines AEC-Q101 qualification, dual-GND layout for high-speed symmetry, and 0.17 pF capacitance optimized for 10 Gbit/s USB3.2/HDMI2.1-making it the only option qualified for automotive SerDes interfaces demanding both speed and reliability.

FAQ
What is the maximum data rate supported by PESD4USB3BBTBR-Q?
The device is validated for 10 Gbit/s operation, demonstrated via USB3.2 Gen 2 eye diagram testing with and without the protector on PCB. Its 0.17 pF channel capacitance and symmetric dual-GND layout maintain signal integrity up to 5 GHz fundamental frequency, supporting HDMI 2.1 and GMSL2 protocols without measurable eye closure.
Can PESD4USB3BBTBR-Q be used on single-ended interfaces like eSATA?
Yes-it supports bidirectional clamping on any high-speed signal line, including single-ended eSATA. The 3.3 V VRWM aligns with eSATA driver output swing, and its 5.4 V clamping voltage protects receiver inputs during ESD events. Layout must maintain controlled impedance and avoid stubs on protected traces.
Why does the device have four n.c. pins (6, 7, 9, 10)?
These terminals are physically present in the DFN2510A-10 mold compound but electrically isolated from the die. They serve mechanical stability and thermal mass functions during reflow, and must remain unconnected-no copper pour, vias, or routing should contact them to prevent parasitic coupling or solder bridging.
Is the thermal pad on the DFN2510A-10 package connected internally?
No-the underside thermal pad in the SOT1176-2 package is not electrically connected to any internal node. It may be left floating or grounded externally for mechanical anchoring and thermal relief, but grounding it does not affect electrical performance or ESD path behavior.
