Product details
Overview
PESD4USB3BTBS-QX 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, 0.5 Ω dynamic resistance, and operates with 3.3 V reverse standoff voltage in automotive-grade AEC-Q101 qualified DFN2510D-10 (SOT1176D) package.
For engineers reviewing the PESD4USB3BTBS-QX datasheet, PESD4USB3BTBS-QX pinout, PESD4USB3BTBS-QX application, or PESD4USB3BTBS-QX equivalent, key selection criteria include ultra-low capacitance for signal integrity, snap-back clamping behavior for low-voltage rail protection, side-wettable flanks for AOI compatibility, and AEC-Q101 qualification for automotive infotainment and camera links.
Technical Context
This device implements a bidirectional snap-back clamping structure optimized for transient suppression on differential high-speed data lanes. Its deep snap-back behavior reduces clamping voltage to ±5.5 V at ±5 A while maintaining sub-0.3 pF capacitance per channel at 1 MHz and 0 V bias - critical for preserving 10 Gbps USB 3.2 eye diagrams and HDMI 2.0 timing margins.
It features four independent ESD protection channels (CH1–CH4), two ground terminals (Pins 3 and 8), and four no-connect pins (6, 7, 9, 10) in a 10-terminal DFN2510D-10 package with 0.5 mm pitch and side-wettable flanks. The design supports impedance-matched PCB routing and avoids DC current sources to prevent latch-up during sustained overvoltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV per IEC 61000-4-2 level 4 (contact); meets ISO 10605 with 330 Ω/150 pF network - ensures system-level robustness in automotive plug-in events. |
| Channel Capacitance | 0.24–0.3 pF at 1 MHz, 0 V - preserves signal integrity on 10 Gbps USB 3.2 and HDMI 2.0 differential pairs without degrading rise time or jitter. |
| Clamping Voltage | ±5.5 V at ±5 A (TLP, 100 ns pulse) - limits transient overshoot below IC I/O absolute maximum ratings during ESD strikes. |
| Dynamic Resistance | 0.5 Ω (TLP, 100 ns) - enables fast energy shunting with minimal voltage drop across protection path during ESD events. |
| Reverse Standoff | 3.3 V - matches standard I/O supply rails for USB, HDMI, and LVDS transceivers without leakage-induced signal distortion. |
| Breakdown Voltage | 6–9 V at 1 mA - provides sufficient margin above 3.3 V operating voltage to avoid false triggering during normal operation. |
| AEC-Q101 Qualified | Qualified per Automotive Electronics Council stress test standard - validated for under-hood and infotainment module deployment up to 150 °C junction temperature. |
Pinout & Package

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 ESDBL3011MUTAG | Single-channel, 0.25 pF, ±12 kV IEC 61000-4-2, SOT-323 package - lower channel count and ESD rating. | Limited to single-lane protection; requires four discrete devices for full USB 3.2 coverage - increases board area and routing complexity. | Select when only one high-speed lane needs protection and space-constrained SOT-323 mounting is required. |
| Vishay VEML3010-001 | Quad-channel, 0.45 pF, ±15 kV, DFN2510-10 but lacks AEC-Q101 qualification and SWF - higher capacitance and no automotive validation. | Not qualified for automotive use; unsuitable for safety-critical camera or display links where AEC-Q101 is mandated. | Consider only for industrial or consumer HDMI/USB applications where automotive qualification is not required. |
Compared with ESDBL3011MUTAG and VEML3010-001, PESD4USB3BTBS-QX uniquely combines quad-channel integration, 0.3 pF capacitance, ±15 kV ESD rating, AEC-Q101 qualification, and side-wettable flanks - making it the only option meeting full automotive infotainment and ADAS interface requirements in a single DFN package.

FAQ
What is the maximum recommended trace length between PESD4USB3BTBS-QX and the protected connector?
For optimal ESD performance, place the device within 3 mm of the high-speed connector per AEC-Q200 layout guidance. Longer traces increase inductance, raising clamping voltage during fast ESD transients and risking downstream IC damage. Ground vias should be placed within 1 mm of each GND pin to minimize loop inductance.
Can PESD4USB3BTBS-QX be used on 5 V-tolerant interfaces like legacy USB 2.0?
Yes - its 6–9 V breakdown voltage and 3.3 V reverse standoff provide sufficient margin for 5 V-tolerant USB 2.0 transceivers. The device clamps transients before reaching destructive levels, and its 0.3 pF capacitance avoids signal degradation on 480 Mbps data lines. No additional series resistance is needed.
Does the device require external biasing or control signals?
No - PESD4USB3BTBS-QX is a passive, bidirectional ESD suppressor with no enable pins, power supplies, or configuration requirements. It operates automatically during ESD events via intrinsic snap-back behavior and remains transparent during normal signal transmission.
How does the dual-GND-pin configuration improve thermal and electrical performance?
Pins 3 and 8 provide separate low-inductance ground return paths for CH1–CH2 and CH3–CH4, respectively. This reduces shared impedance, minimizes crosstalk between protected lanes, and improves heat dissipation during multi-channel ESD events - critical for simultaneous HDMI TMDS and USB 3.2 protection in compact automotive modules.
