Product details
Overview
PESD4USB3BCTBR-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, 0.19 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.
For engineers reviewing the PESD4USB3BCTBR-Q datasheet, PESD4USB3BCTBR-Q pinout, PESD4USB3BCTBR-Q application, or PESD4USB3BCTBR-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 validated performance in 10 Gbit/s eye diagrams with and without device insertion.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance, enabling low-voltage clamping during ESD transients while maintaining sub-0.2 pF line capacitance at 1 MHz and 1.5 V bias. It supports bidirectional protection across four independent channels with two dedicated ground terminals.
Designed for high-speed differential signaling, it meets IEC 61000-4-5 surge (8.2 A peak), IEC 61000-4-4 EFT (40 A into 50 Ω), and ISO 10605 (±15 kV contact discharge), with breakdown voltage ≥5.5 V and dynamic resistance ≤0.34 Ω under TLP stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | ±3.3 V - Ensures no conduction during normal 3.3 V interface operation, preserving signal integrity. |
| Diode Capacitance (Cd) | 0.19 pF (typ.) - Minimizes signal distortion on 10 Gbit/s USB 3.2 and HDMI 2.1 links. |
| Clamping Voltage (VCL) | 5.4 V @ 6.5 A (8/20 µs) - Limits transient voltage seen by downstream PHY to safe levels. |
| ESD Withstand | ±15 kV IEC 61000-4-2 - Exceeds Level 4 immunity for robust handling in manufacturing and field use. |
| Peak Pulse Current (IPP) | 8.2 A (IEC 61000-4-5) - Sustains high-energy surges without degradation in automotive infotainment systems. |
| Dynamic Resistance (Rdyn) | 0.34 Ω (TLP, ±10 A) - Enables fast, low-impedance clamping to suppress ESD energy before IC damage occurs. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress. |
Pinout & Package
Encapsulated in a leadless DFN2510A-10 (SOT1176-2) surface-mount package measuring 1.0 × 2.5 × 0.5 mm, with exposed thermal pad and 10-terminal layout optimized for high-density PCB routing and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection input for first high-speed data line (e.g., USB3 TX+/RX+ pair leg). |
| 2 | CH2 | ESD protection input for second high-speed data line (e.g., USB3 TX−/RX− pair leg). |
| 3 | GND | Dedicated ground return path for CH1–CH2 clamping current; must be low-inductance connection. |
| 4 | CH3 | ESD protection input for third high-speed data line (e.g., HDMI TMDS clock or data channel). |
| 5 | CH4 | ESD protection input for fourth high-speed data line (e.g., HDMI auxiliary or GMSL SerDes lane). |
| 6, 7, 9, 10 | n.c. | No internal connection - electrically isolated; may be used as keep-out or thermal relief zones. |
| 8 | GND | Second dedicated ground terminal for CH3–CH4 clamping current; enables balanced return paths. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional 4-channel architecture | Independent protection for two differential pairs without shared clamping nodes, preserving common-mode rejection. |
| Snap-back clamping mechanism | Dynamic resistance drops to 0.34 Ω during ESD event, reducing clamping voltage to 5.4 V and limiting energy transfer to protected IC. |
| Ultra-low 0.19 pF capacitance | Enables <1 dB insertion loss up to 10 GHz, verified via USB 3.2 eye diagram testing with and without device. |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (−55 °C to +150 °C) and storage (−65 °C to +150 °C), supporting under-hood and display module use. |
| DFN2510A-10 footprint | 1.0 mm width allows placement adjacent to high-speed connectors without trace stubs; 0.5 mm profile suits slim display bezels. |
Applications
| USB 3.2 Gen 2 Interface Protection | HDMI 2.1 Source Port Protection |

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 ESD7481 | 0.25 pF capacitance, ±12 kV IEC 61000-4-2, single-channel (requires 4 devices) | Lacks AEC-Q101 qualification; higher capacitance limits use in 10 Gbit/s links | Select when cost-per-channel is prioritized over automotive qualification and 10 Gbit/s compliance. |
| Vishay VEML6030X01 | 0.22 pF, ±15 kV, but only 2-channel configuration; requires dual placement for 4-line protection | Not qualified to AEC-Q101; lacks dual-GND layout for balanced return paths | Prefer for space-constrained non-automotive designs where 4-line integration is less critical than footprint size. |
Compared with ESD7481 and VEML6030X01, PESD4USB3BCTBR-Q uniquely delivers integrated 4-channel protection, AEC-Q101 qualification, dual-GND terminals, and 0.19 pF capacitance-enabling single-device 10 Gbit/s USB 3.2 and HDMI 2.1 protection in automotive modules without compromising signal fidelity or reliability.

FAQ
What is the maximum data rate supported by PESD4USB3BCTBR-Q?
The device is validated for 10 Gbit/s operation, as confirmed by USB 3.2 Gen 2 eye diagram testing (Fig. 5–6 in the datasheet). Its 0.19 pF capacitance and low dynamic resistance ensure minimal insertion loss and jitter impact on high-speed differential signals, making it suitable for USB 3.2 Gen 2, HDMI 2.1, and GMSL links.
Does PESD4USB3BCTBR-Q require external biasing or control signals?
No. It is a passive, bidirectional ESD protection diode array with no power supply or enable pins. It operates solely based on its intrinsic clamping characteristics-conducting only during ESD transients above its breakdown voltage-and remains fully transparent during normal 3.3 V signal operation.
How does the dual-GND pin configuration improve ESD performance?
Pins 3 and 8 provide separate low-inductance ground return paths for CH1–CH2 and CH3–CH4, respectively. This reduces ground loop inductance and minimizes voltage overshoot during simultaneous multi-line ESD events, improving clamping consistency and preventing crosstalk-induced false triggering in multi-lane interfaces.
Can PESD4USB3BCTBR-Q be used in non-automotive applications like consumer docking stations?
Yes. While AEC-Q101 qualified, its electrical specs-including ±15 kV ESD rating, 0.19 pF capacitance, and 10 Gbit/s validation-are equally beneficial in consumer USB-C docking stations, portable monitors, and HDMI 2.1 adapters where signal integrity and robustness are critical.
