Product details
Overview
PESD4USB5UBTTS-Q from Nexperia is a unidirectional ESD protection diode array in DFN2510D-10 (SOT1165D) package, designed for high-speed serial interfaces including USB 3.2 Gen1, HDMI 2.1, and GMSL SerDes. It delivers 5 V reverse standoff voltage, 0.4 pF typical line capacitance, and ±15 kV IEC 61000-4-2 contact ESD protection - enabling signal integrity preservation in automotive infotainment and camera links.
For engineers reviewing the PESD4USB5UBTTS-Q datasheet, PESD4USB5UBTTS-Q pinout, PESD4USB5UBTTS-Q application, or PESD4USB5UBTTS-Q equivalent, this device addresses critical trade-offs between ultra-low capacitance, sub-3 V clamping under 6.5 A surge, and AEC-Q101-qualified reliability for high-speed differential data lines in constrained PCB layouts.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance, achieving 0.2 Ω dynamic resistance and 2.9 V clamping voltage at 6.5 A (8/20 µs), significantly reducing transient voltage overshoot during ESD events. Its matched 0.5 mm trace spacing and side-wettable flanks support automated optical inspection and fine-pitch reflow soldering.
It operates as a four-channel unidirectional TVS array with dedicated ground pins (pins 3 and 8) and two isolated no-connect terminals (pins 6, 7, 9, 10). The 0.4 pF capacitance per channel is measured on pin 1 at 1 MHz and 0 V bias, ensuring minimal signal distortion on SuperSpeed USB and LVDS lanes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 5 V - defines maximum continuous operating voltage before leakage exceeds 100 nA; matches 5 V interface rails. |
| Diode Capacitance (Cd) | 0.4 pF (typ.) - enables >5 Gbps data rates on USB 3.2 and HDMI 2.1 without measurable insertion loss. |
| Clamping Voltage (VCL) | 2.9 V @ 6.5 A (8/20 µs) - limits transient overvoltage to safe levels for downstream PHY receivers. |
| Dynamic Resistance (Rdyn) | 0.2 Ω - ensures rapid voltage collapse post-breakdown, minimizing energy dissipation in protected ICs. |
| ESD Rating | ±15 kV (IEC 61000-4-2 contact) - exceeds Level 4 immunity requirement for automotive and industrial end-equipment. |
| Breakdown Voltage (VBR) | 5.5–11.5 V (min–max at 1 mA) - guarantees robust turn-on margin above VRWM while avoiding false triggering. |
| Ambient Temperature Range | −55 °C to +150 °C - supports under-hood and display module deployment in automotive environments. |
Pinout & Package
DFN2510D-10 (SOT1165D) is a leadless, 2.5 mm × 1.0 mm × 0.75 mm thin small outline package with side-wettable flanks for AOI-compatible reflow. Dimensions include 0.5 mm pitch, 10 terminals, and dual exposed ground pads (pins 3 and 8).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection path for first high-speed differential pair (e.g., USB 3.2 TX+/−) |
| 2 | CH2 | ESD protection path for second differential pair (e.g., HDMI TMDS0+) |
| 3 | GND | Primary low-inductance ground return for CH1–CH2; connects to thermal pad |
| 4 | CH3 | ESD protection path for third differential pair (e.g., HDMI TMDS1+) |
| 5 | CH4 | ESD protection path for fourth differential pair (e.g., GMSL Data+) |
| 6, 7, 9, 10 | n.c. | No internal connection; electrically isolated; used for mechanical stability and solder joint visibility |
| 8 | GND | Secondary ground terminal; improves current sharing and reduces ground loop inductance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance routing | 0.4 pF/channel preserves signal integrity on >5 Gbps serial links without equalization overhead |
| Deep snap-back clamping | 0.2 Ω Rdyn and 2.9 V VCL at 6.5 A reduce peak stress on SerDes receiver inputs by >40% vs. standard TVS |
| Side-wettable flanks (SWF) | Enables 100% automated optical inspection of solder joints on all 10 terminals, eliminating X-ray dependency |
| AEC-Q101 qualification | Validated for automotive use per stress test requirements including HTGB, HTRB, and temperature cycling |
| Pass-through signal layout | Linear pin arrangement (CH1–CH2–GND–CH3–CH4) allows direct trace routing beneath device without vias |
Applications
| Automotive Infotainment USB | HDMI 2.1 Display Interface |
|---|---|
Use Scenario: Protecting USB 3.2 Gen1 ports in head-unit docking stations against ESD from user plugging/unplugging. IC Role / Device Role / Timing Role: Unidirectional ESD clamp placed directly at connector, shunting transients before reaching USB controller PHY.

IC Role / Device Role / Timing Role: Four-channel discrete protection for TMDS+/- pairs and HPD/CEC lines in compact layout. Use Value: Matched 0.5 mm trace spacing enables clean 4K60 routing; dual GND pins minimize ground bounce during multi-line discharge. |
| GMSL Serializer Links | LVDS Camera Interfaces |
Use Scenario: Safeguarding GMSL SerDes data lanes in rear-view camera modules exposed to chassis-level ESD. IC Role / Device Role / Timing Role: Per-lane unidirectional TVS on serialized video/data channels, placed within 3 mm of connector. Use Value: 2.9 V clamping ensures receiver input stays below absolute maximum ratings during 15 kV contact discharge. |
Use Scenario: Protecting LVDS clock and data pairs in ADAS surround-view systems from board-level ESD coupling. IC Role / Device Role / Timing Role: Low-capacitance ESD suppression on differential pairs carrying 100+ MHz pixel clocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | Bidirectional configuration; 0.5 pF capacitance; 3.6 V clamping @ 4 A; no AEC-Q101 qualification | Suitable for non-automotive USB 2.0/HDMI 1.4 where bidirectional protection suffices and temperature range ≤105 °C | Select when system-level ESD polarity is undefined and automotive qualification is not required. |
| ESD56411D05-2/TR | Unidirectional; 0.35 pF capacitance; 3.0 V clamping @ 5 A; AEC-Q101 qualified; DFN1610-6 package (6-pin) | Supports only two channels; lacks dual-GND architecture and SWF; smaller footprint but higher thermal resistance | Choose for space-constrained dual-lane designs where 0.35 pF is prioritized over four-channel integration. |
Compared with TPD4E05U06DQAR and ESD56411D05-2/TR, PESD4USB5UBTTS-Q uniquely combines four-channel unidirectional protection, AEC-Q101 qualification, side-wettable flanks, and dual-GND low-inductance grounding - making it the only option qualified for full automotive GMSL/HDMI 2.1 front-end protection in single-package form.

FAQ
What is the maximum recommended trace length between PESD4USB5UBTTS-Q and the protected connector?
For optimal ESD performance, place the device within 3 mm of the connector pin. Longer traces increase inductance, raising clamping voltage during fast transients. The DFN2510D-10's side-wettable flanks and linear pinout enable direct routing without vias, supporting this constraint in dense HDI layouts.
Can PESD4USB5UBTTS-Q be used on bidirectional buses like USB 2.0 D+ and D−?
Yes - though unidirectional, it protects USB 2.0 data lines when installed with cathodes toward the protected IC (anodes grounded). Its 5 V VRWM aligns with USB 2.0 signaling, and 0.4 pF capacitance avoids signal integrity issues at 480 Mbps. Confirm polarity alignment per schematic during layout.
Does the device require external decoupling capacitors for ESD suppression?
No - PESD4USB5UBTTS-Q functions as a standalone ESD suppressor and does not require series resistors or parallel capacitors. Its snap-back behavior and 0.2 Ω dynamic resistance provide self-limiting conduction. Adding external capacitance would degrade high-frequency response and violate the 0.4 pF design target.
How does the dual-GND configuration (pins 3 and 8) improve protection performance?
Dual GND terminals halve the effective ground inductance compared to single-GND arrays, reducing voltage overshoot during multi-channel simultaneous discharge. This is critical for HDMI/GMSL where multiple differential pairs experience correlated ESD events - measured clamping improvement is ≥15% versus single-GND equivalents.
