Product details
Overview
PESD4USB3UCTBR-Q from Nexperia is a unidirectional ESD protection diode array in DFN2510A-10 (SOT1176-2) package, designed for high-speed serial interfaces including USB 3.2 (10 Gbit/s), HDMI 2.1 (12G FRL), and GMSL SerDes. It delivers ±15 kV IEC 61000-4-2 ESD protection, 0.29 pF typical line capacitance, and 2.8 V clamping voltage at 8 A TLP.
For engineers reviewing the PESD4USB3UCTBR-Q datasheet, PESD4USB3UCTBR-Q pinout, PESD4USB3UCTBR-Q application, or PESD4USB3UCTBR-Q equivalent, this device is selected for ultra-low-capacitance transient suppression on differential high-speed data lanes where signal integrity and eye diagram preservation are critical - confirmed by USB3.2 and HDMI 2.1 eye diagrams with/without device.
Technical Context
This device implements four independent unidirectional ESD protection channels in a single 10-terminal leadless DFN package, each featuring snap-back clamping behavior with negative dynamic resistance to minimize clamping voltage during ESD transients. Its architecture avoids DC bias dependency and supports bidirectional signal flow on AC-coupled lines.
It meets AEC-Q101 qualification for automotive use and satisfies IEC 61000-4-2 (±15 kV contact), IEC 61000-4-4 (36 A), and ISO 10605 (±15 kV, 330 Ω/150 pF) requirements. The 0.29 pF capacitance per channel is measured on pin 1 at 1 MHz and 1.5 V reverse bias, ensuring minimal insertion loss up to 10 GHz.
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. |
| Clamping Voltage (VCL) | 2.8 V at 8 A TLP (100 ns) - limits voltage seen by downstream PHY to safe levels during ESD events. |
| Diode Capacitance (Cd) | 0.29 pF typical per channel at 1 MHz - preserves signal integrity on 10 Gbit/s USB3.2 and 12G HDMI 2.1 links. |
| ESD Rating | ±15 kV IEC 61000-4-2 contact discharge - exceeds Level 4 immunity for robust system-level ESD compliance. |
| Package | DFN2510A-10 (SOT1176-2), 1.0 × 2.5 × 0.5 mm - ultra-small footprint compatible with dense high-speed PCB layouts. |
| AEC-Q101 Qualified | Qualified for automotive infotainment and ADAS camera modules - validated for -55 °C to +150 °C ambient operation. |
Pinout & Package
DFN2510A-10 (SOT1176-2) is a leadless, ultra-thin surface-mount package with 10 terminals, 1.0 mm width, 2.5 mm length, and 0.5 mm height. Ground terminals are placed on both sides (pins 3 and 8) to minimize inductance and improve ESD current return path symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection input for first high-speed differential pair (e.g., USB3.2 TX+/−, HDMI TMDS0+) |
| 2 | CH2 | ESD protection input for second high-speed differential pair (e.g., USB3.2 RX+/−, HDMI TMDS1+) |
| 3 | GND | Dedicated low-inductance ground return for CH1–CH2 protection paths |
| 4 | CH3 | ESD protection input for third high-speed differential pair (e.g., HDMI TMDS2+, GMSL DATA+) |
| 5 | CH4 | ESD protection input for fourth high-speed differential pair (e.g., HDMI CLOCK+, GMSL CLK+) |
| 6, 7, 9, 10 | n.c. | No-connect terminals - electrically isolated and not bonded internally |
| 8 | GND | Second dedicated low-inductance ground return for CH3–CH4 protection paths |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional 4-channel ESD protection | Enables independent protection of four high-speed signal lines without affecting DC bias or common-mode range. |

| 0.29 pF channel capacitance | Minimizes signal distortion and insertion loss on 10 Gbit/s USB3.2 and 12G HDMI 2.1 links - verified by eye diagram testing. |
| AEC-Q101 qualified | Validated for automotive-grade reliability across -55 °C to +150 °C, supporting infotainment and camera module deployment. |
| IEC 61000-4-4 surge robustness | Withstands 36 A fast transient burst (1.8 kV into 50 Ω) - protects against coupled noise in noisy vehicle environments. |
Applications
| USB 3.2 Gen 2 Interface Protection | HDMI 2.1 12G FRL Link Protection |
|---|---|
|
Use Scenario: Protecting SuperSpeed USB 3.2 Gen 2 (10 Gbit/s) host/device ports in automotive infotainment head units and docking stations. IC Role / Device Role / Timing Role: Unidirectional ESD clamp placed directly at connector, shunting transients before reaching USB 3.2 PHY IC. Use Value: Maintains clean eye diagram (Fig. 5 vs Fig. 6) with <0.5 dB insertion loss at 5 GHz - enabling full Gen 2 link training and stable 10 Gbit/s operation. |
Use Scenario: Safeguarding HDMI 2.1 Fixed Rate Link (12G FRL) inputs on automotive A/V monitors and rear-seat entertainment systems. IC Role / Device Role / Timing Role: Four-channel ESD suppressor on TMDS clock and data lanes, positioned between connector and HDMI receiver. Use Value: Preserves 12G FRL eye opening under worst-case cable model (WCM3, Fig. 9) - prevents bit errors and link dropouts in long-cable automotive video links. |
| GMSL SerDes Video Link Protection | Automotive LVDS Camera Interface |
|
Use Scenario: ESD hardening of Gigabit Multimedia Serial Link (GMSL) serializer/deserializer channels in surround-view camera systems. IC Role / Device Role / Timing Role: Per-lane unidirectional clamp on GMSL DATA+/− and CLK+/− pairs, mounted adjacent to FAKRA connector. Use Value: Enables >15 kV ESD immunity without degrading GMSL jitter budget - verified by eye diagrams at 3.125 Gbps with <0.3 UI degradation. |
Use Scenario: Protecting LVDS video signals from front/rear cameras in ADAS domain controllers and central gateways. IC Role / Device Role / Timing Role: Low-capacitance ESD suppressor on LVDS differential pairs, placed before LVDS receiver termination network. Use Value: Adds <0.15 pF per lane to total trace capacitance - negligible impact on LVDS rise/fall time (<10 ps delay shift) and common-mode rejection. |
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 typical capacitance, bidirectional, 5.5 V VRWM | Higher capacitance limits use to ≤5 Gbit/s interfaces (e.g., USB 2.0, DisplayPort 1.2); not recommended for USB3.2 Gen 2 or HDMI 2.1. | Select when bidirectional protection is required and VRWM >3.3 V is acceptable - e.g., legacy 5 V tolerant interfaces. |
| ESD5451N-2/TR | 0.35 pF typical capacitance, unidirectional, 3.3 V VRWM, AEC-Q101 qualified | Higher clamping voltage (3.5 V at 8 A TLP) and lower ESD rating (±12 kV) reduce margin for stringent automotive ESD test plans. | Choose for cost-sensitive automotive designs where 0.35 pF capacitance and ±12 kV ESD meet system-level requirements. |
Compared with TPD4E05U06DQAR and ESD5451N-2/TR, PESD4USB3UCTBR-Q provides the lowest capacitance (0.29 pF) and tightest clamping (2.8 V @ 8 A), making it uniquely suitable for 10 Gbit/s USB3.2 and 12G HDMI 2.1 while maintaining AEC-Q101 compliance.

FAQ
What is the maximum data rate supported by PESD4USB3UCTBR-Q?
PESD4USB3UCTBR-Q is validated for 10 Gbit/s USB 3.2 Gen 2 and 12 Gbit/s HDMI 2.1 FRL operation, with eye diagrams confirming signal integrity retention (Figs. 5–10 in datasheet). Its 0.29 pF capacitance and low dynamic resistance ensure minimal jitter and insertion loss up to 10 GHz.
Can PESD4USB3UCTBR-Q be used on bidirectional differential interfaces like USB 3.2?
Yes - although unidirectional, it is placed on AC-coupled differential lanes where the signal swings symmetrically around ground. The 3.3 V VRWM allows full swing of ±1.65 V signals without forward conduction, and its snap-back clamping responds identically to positive/negative ESD transients.
How does the snap-back clamping behavior affect PCB layout?
Snap-back requires strict avoidance of DC bias sources on protected lines - do not connect to batteries or constant-voltage rails. Layout must provide low-inductance ground paths (pins 3 and 8) and avoid stubs longer than 2 mm to prevent false triggering or oscillation during ESD events.
Is PESD4USB3UCTBR-Q compatible with lead-free reflow profiles?
Yes - it is qualified for standard lead-free reflow per J-STD-020, with peak temperature up to 260 °C. The recommended footprint (Fig. 18) uses 0.1 mm stencil thickness and 2.45 mm × 1.25 mm solder land dimensions to ensure reliable void-free solder joints in DFN2510A-10 package.
