Product details
Overview
PESD4USB3BTTS-Q from Nexperia is a bidirectional ESD protection diode array designed for high-speed serial interfaces including SuperSpeed USB 3.2 (10 Gbps), HDMI 2.0, DisplayPort, eSATA, LVDS, and GMSL SerDes. It delivers ±15 kV IEC 61000-4-2 contact ESD protection, 0.3 pF channel capacitance, and 0.5 Ω dynamic resistance in a DFN2510D-10 (SOT1165D) package with side-wettable flanks - enabling AOI-compatible automotive infotainment and camera interface designs.
For engineers reviewing the PESD4USB3BTTS-Q datasheet, PESD4USB3BTTS-Q pinout, PESD4USB3BTTS-Q application, or PESD4USB3BTTS-Q equivalent, this page provides verified electrical parameters, validated automotive qualification (AEC-Q101), exact pin mapping for four-channel differential signal routing, and real-world use cases in USB 3.2 Gen 2 and GMSL link protection.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance to achieve deep voltage clamping during ESD transients. Its low 0.3 pF capacitance per channel preserves signal integrity on 10 Gbps USB 3.2 differential pairs while maintaining <5.5 V clamping at ±5 A TLP current.
The DFN2510D-10 package features matched 0.5 mm trace spacing and side-wettable flanks for automated optical inspection. All four protected channels are symmetrically arranged with dual ground terminals (pins 3 and 8) to minimize ground loop inductance in high-frequency layouts.
Key Specifications

Applications
| USB 3.2 Gen 2 Interface Protection | HDMI 2.0 Link Protection |
|---|---|
|
Use Scenario: Protecting host controller and peripheral ports in automotive infotainment head units handling 10 Gbps SuperSpeed USB 3.2 data transfers. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed directly at connector entry point to shunt transients before reaching USB 3.2 PHY. Use Value: 0.3 pF capacitance avoids signal degradation at 5 GHz fundamental frequency; ±15 kV rating meets ISO 10605 automotive ESD requirements. |
Use Scenario: Shielding HDMI 2.0 source and sink ports in vehicle rear-seat entertainment displays against cable-discharge events. IC Role / Device Role / Timing Role: Four-channel ESD suppressor applied across all three TMDS differential pairs and HPD line in compact DFN package. Use Value: Dual GND pins (3 & 8) reduce ground bounce during multi-lane ESD strikes; 0.5 Ω Rdyn ensures sub-6 V clamping under 8/20 µs surge. |
| GMSL SerDes Protection | LVDS Camera Interface Protection |
|
Use Scenario: Safeguarding GMSL serializer outputs in ADAS front cameras exposed to ESD during assembly, service, or environmental exposure. IC Role / Device Role / Timing Role: Channel-matched ESD protection on serialized video lanes (CLK, DATA0–DATA3) with minimal skew impact. Use Value: Symmetric capacitance (<0.3 pF) across all channels maintains inter-pair timing alignment critical for GMSL frame synchronization. |
Use Scenario: Securing LVDS video links between automotive instrument clusters and TFT displays subjected to repeated hot-plug and static discharge. IC Role / Device Role / Timing Role: Low-capacitance ESD array placed at display connector to protect display driver IC inputs. Use Value: 3.3 V VRWM aligns with LVDS common-mode range; snap-back behavior prevents latch-up during sustained overvoltage conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | Higher 0.5 pF capacitance; ±12 kV IEC 61000-4-2 rating; no AEC-Q101 qualification | Targeted at consumer-grade USB 3.0 (5 Gbps), not automotive or 10 Gbps systems | Select only for non-automotive, cost-sensitive designs where 10 Gbps margin and AEC compliance are unnecessary |
| ESD56081D05 | 0.25 pF typical capacitance; ±20 kV ESD rating; same DFN2510D-10 footprint but different pinout (GND on pins 1 & 10) | Requires PCB redesign due to inverted ground pin placement; optimized for PCIe Gen4 | Choose only when higher ESD margin is required and layout revision is feasible for ground pin relocation |
Compared with SP1006-04UTG and ESD56081D05, PESD4USB3BTTS-Q uniquely balances 10 Gbps signal fidelity (0.3 pF), automotive qualification (AEC-Q101), and production-ready DFN2510D-10 layout compatibility - making it optimal for USB 3.2 Gen 2 and GMSL in OEM automotive programs.

FAQ
What is the maximum data rate supported by PESD4USB3BTTS-Q?
PESD4USB3BTTS-Q supports up to 10 Gbps data rates, validated for SuperSpeed USB 3.2 Gen 2 operation. Its 0.3 pF channel capacitance and matched trace spacing preserve signal integrity at 5 GHz fundamental frequency, meeting HDMI 2.0 and DisplayPort 1.4 timing budgets without equalization overhead.
Does PESD4USB3BTTS-Q require external biasing or control signals?
No. PESD4USB3BTTS-Q is a passive bidirectional ESD protection device with no power supply, enable pin, or control interface. It operates solely via avalanche breakdown and snap-back clamping triggered by transient overvoltage - requiring zero configuration or firmware integration.
Can PESD4USB3BTTS-Q be used on single-ended lines like HDMI HPD or USB VBUS?
No. PESD4USB3BTTS-Q is configured exclusively for differential signal protection (CH1–CH4). Its internal architecture lacks dedicated single-ended paths; using it on HPD or VBUS would leave those lines unprotected and may compromise clamping performance on adjacent differential pairs.
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 mutual coupling during multi-lane ESD events and lowers overall clamping impedance - measured at 0.5 Ω dynamic resistance - ensuring consistent sub-6 V clamping across all four channels simultaneously.
