Product details
Overview
PESD4USB5UBTBR-Q from Nexperia is a unidirectional ESD protection diode array designed for four high-speed signal lines in USB 3.2, HDMI 2.1, and GMSL SerDes interfaces. It delivers 5 V reverse standoff voltage, 0.29 pF typical line capacitance, ±15 kV IEC 61000-4-2 ESD immunity, 2.8 V clamping at 8 A TLP, and AEC-Q101 qualification for automotive infotainment systems.
For engineers reviewing the PESD4USB5UBTBR-Q datasheet, PESD4USB5UBTBR-Q pinout, PESD4USB5UBTBR-Q application, or PESD4USB5UBTBR-Q equivalent, this device is selected for ultra-low-capacitance transient suppression on 10 Gbit/s differential buses where signal integrity, ESD robustness, and automotive-grade reliability are jointly required.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance to achieve sub-3 V clamping during ESD transients while maintaining <0.34 pF capacitance per channel at 1.5 V bias. Its DFN2510A-10 package places four active channels and dual ground terminals in a 1.0 × 2.5 mm footprint optimized for controlled-impedance PCB routing.
It supports bidirectional surge immunity per IEC 61000-4-5 (8.2 A peak) and repeatable 36 A IEC 61000-4-4 pulses into 50 Ω, with breakdown voltage ≥6 V and leakage <100 nA at 5 V - enabling robust protection without DC loading of sensitive high-speed receivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V reverse standoff voltage - ensures no conduction during normal 5 V interface operation, preserving signal swing and DC bias. |
| Clamping Voltage (VCL) | 2.8 V at 8 A TLP - limits transient overvoltage to safe levels for USB 3.2 Gen2 and HDMI 2.1 FRL receivers. |
| Capacitance (Cd) | 0.29 pF typical per channel at 1 MHz/1.5 V - minimizes insertion loss and eye diagram degradation at 10 Gbit/s data rates. |
| ESD Rating | ±15 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds automotive and industrial ESD immunity requirements. |
| Dynamic Resistance (Rdyn) | 0.19 Ω at ±10 A TLP - enables fast, low-impedance clamping critical for protecting gigabit serial links. |
| Breakdown Voltage (VBR) | Min 6 V at 1 mA - provides margin above VRWM to prevent false triggering during voltage transients or noise spikes. |
| AEC-Q101 Qualified | Qualified for automotive applications - validated for temperature cycling, HTRB, and ESD stress per AEC standard. |
Pinout & Package
Encapsulated in a leadless DFN2510A-10 (SOT1176-2) plastic package measuring 1.0 × 2.5 × 0.5 mm, this device uses a 10-terminal surface-mount outline with two dedicated ground pins and four isolated signal channels.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection input for first high-speed differential pair (e.g., USB3 TX+/− or HDMI TMDS0+). |
| 2 | CH2 | ESD protection input for second high-speed differential pair (e.g., USB3 RX+/− or HDMI TMDS1+). |
| 3 | GND | Primary ground return path for CH1–CH2 clamping current; must be low-inductance connection to system ground plane. |
| 4 | CH3 | ESD protection input for third high-speed differential pair (e.g., HDMI TMDS2+ or GMSL DATA+). |
| 5 | CH4 | ESD protection input for fourth high-speed differential pair (e.g., HDMI CLOCK+ or GMSL CLK+). |
| 6, 7, 9, 10 | n.c. | No internal connection - electrically isolated; may be left floating or tied to ground for mechanical stability only. |
| 8 | GND | Secondary ground return path for CH3–CH4 clamping current; improves symmetry and reduces ground bounce across all channels. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional 4-channel architecture | Enables independent protection of four high-speed signal lines without cross-talk or shared clamping paths. |
| Snap-back clamping mechanism | Reduces clamping voltage by >30% versus conventional TVS diodes under 8–16 A TLP pulses, minimizing receiver stress. |
| 0.29 pF channel capacitance | Preserves signal integrity up to 12 Gbit/s (HDMI 2.1 FRL), with <0.5 dB insertion loss at 5 GHz. |
| Dual GND pins (pins 3 & 8) | Provides balanced return paths for all four channels, reducing ground loop inductance and improving ESD current distribution. |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (−55 °C to +150 °C) and lifetime reliability in infotainment head units and camera modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.5 pF capacitance, 5.5 V VRWM, ±12 kV ESD rating, single-supply bidirectional design | Better suited for lower-speed USB 2.0 or MIPI D-PHY where higher capacitance is tolerable | Select when cost sensitivity outweighs 10 Gbit/s signal integrity requirements and bidirectional clamping is preferred. |
| ESD5451N-2/TR | 0.35 pF capacitance, 5 V VRWM, ±15 kV ESD, dual-GND layout but only 2-channel configuration | Requires two devices for full 4-lane coverage; larger board area due to SO-8 package | Choose if existing PCB layout uses SO-8 footprints and 4-channel integration is not mandatory. |
Compared with TPD4E05U06DQAR and ESD5451N-2/TR, PESD4USB5UBTBR-Q uniquely combines 0.29 pF capacitance, AEC-Q101 qualification, and integrated 4-channel + dual-GND DFN2510A-10 packaging - making it the only option qualified for automotive HDMI 2.1 and USB 3.2 Gen2 front-end protection without performance trade-offs.

FAQ
What is the maximum data rate supported by PESD4USB5UBTBR-Q without signal degradation?
PESD4USB5UBTBR-Q maintains signal integrity up to 12 Gbit/s, as validated by HDMI 2.1 FRL eye diagrams (Figs. 7–10) and USB 3.2 Gen2 10 Gbit/s testing (Figs. 5–6). Its 0.29 pF capacitance and optimized layout ensure <0.5 dB insertion loss at 5 GHz, meeting USB-IF and HDMI Forum channel compliance requirements.
Can PESD4USB5UBTBR-Q be used on bidirectional buses like USB 2.0?
No - PESD4USB5UBTBR-Q is unidirectional and rated for 5 V reverse standoff only. It is not suitable for USB 2.0 full-speed or low-speed lines that require symmetric ±5 V clamping. For such applications, a bidirectional ESD array like PESD5V0S1BA should be selected instead.
How does the dual-GND configuration improve ESD performance?
Pins 3 and 8 provide separate low-inductance return paths for CH1–CH2 and CH3–CH4, respectively. This reduces ground bounce during simultaneous multi-line ESD events and prevents coupling between protected channels - critical for maintaining skew control in HDMI TMDS and GMSL clock/data pairs.
Is thermal derating required for continuous operation at 150 °C ambient?
No thermal derating is needed for ESD protection function, as the device draws negligible current (<100 nA) under normal bias. Its AEC-Q101 qualification includes 1000-hour high-temperature reverse bias (HTRB) testing at 150 °C, confirming stable VRWM and leakage performance across the full automotive temperature range.
