Product details
Overview
PESD4USB3BBTBS-Q from Nexperia is a bidirectional ESD protection diode array in DFN2510D-10 (SOT1176D) package, designed for high-speed serial interfaces including USB 3.2 Gen1, HDMI 2.1, DisplayPort, eSATA, LVDS, and GMSL SerDes. It delivers ±15 kV IEC 61000-4-2 contact ESD protection, 0.23 pF typical line capacitance, and 0.32 Ω dynamic resistance-enabling signal integrity preservation in automotive infotainment and camera links.
For engineers reviewing the PESD4USB3BBTBS-Q datasheet, PESD4USB3BBTBS-Q pinout, PESD4USB3BBTBS-Q application, or PESD4USB3BBTBS-Q equivalent, this device is selected for ultra-low-capacitance transient suppression on differential high-speed data lanes where insertion loss and impedance matching are critical design constraints.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance to achieve deep voltage clamping during ESD transients-reducing VCL to 5 V at 6.5 A (8/20 µs). Its matched 0.5 mm trace spacing and side-wettable flanks support automated optical inspection and reliable reflow soldering in compact automotive PCB layouts.
It operates with a 3.3 V reverse standoff voltage (VRWM) and exhibits <100 nA reverse leakage at rated VRWM. The four-channel architecture protects two differential pairs (CH1–CH4), with dedicated GND pins (pins 3 and 8) enabling low-inductance return paths essential for high-frequency ESD current dissipation.
Key Specifications

Applications
| USB 3.2 Gen1 Interface Protection | HDMI 2.1 Source Port Protection |
|---|---|
|
Use Scenario: Protecting SuperSpeed USB 3.2 differential pairs (TX/RX) on automotive head-unit USB-C ports exposed to user-handling ESD. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point, before USB 3.2 PHY. Use Value: 0.23 pF capacitance avoids signal degradation at 5 Gbps; ±15 kV ESD rating ensures compliance with IEC 61000-4-2 Level 4 in vehicle cabin environments. |
Use Scenario: Shielding HDMI 2.1 source-side TMDS channels in digital dash displays against cable-discharge events during hot-plug. IC Role / Device Role / Timing Role: Four-channel ESD clamp on two TMDS differential pairs (clock + data lanes), mounted adjacent to HDMI connector. Use Value: Matched 0.5 mm trace spacing enables controlled-impedance layout; 5 V clamping prevents HDMI receiver latch-up during 8/20 µs surges. |
| GMSL SerDes Camera Link | LVDS Automotive Display Interface |
|
Use Scenario: Safeguarding GMSL serializer output lines connecting ADAS cameras to domain controllers over long harnesses. IC Role / Device Role / Timing Role: ESD protection array on serializer's differential video/data outputs, located at PCB edge near FAKRA connector. Use Value: 0.32 Ω dynamic resistance ensures fast clamping response (<1 ns), limiting transient overshoot that could corrupt serialized pixel data. |
Use Scenario: Protecting LVDS video links between infotainment SoC and TFT display module in center console assemblies. IC Role / Device Role / Timing Role: Four-channel clamp on dual LVDS pairs (clock + data), placed immediately after SoC output drivers. Use Value: Low 3.3 V VRWM avoids DC loading; side-wettable flanks support AOI verification of fine-pitch solder joints in high-reliability production. |
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 ESD7351 | 0.35 pF capacitance; ±12 kV IEC 61000-4-2; same DFN2510-10 package | Limited to USB 2.0 and lower-speed LVDS due to higher capacitance and lower ESD rating | Select when cost sensitivity outweighs need for USB 3.2/GMSL bandwidth and automotive-level ESD margin. |
| Vishay VEML3010 | 0.25 pF; ±15 kV; but only dual-channel (2-line) configuration; different 1.6 × 1.6 mm package | Requires two devices for full 4-line protection; larger footprint limits routing density in tight camera modules | Prefer for non-automotive consumer designs where board area is less constrained and AEC-Q101 is not required. |
Compared with ESD7351 and VEML3010, PESD4USB3BBTBS-Q uniquely combines quad-channel protection, 0.23 pF capacitance, ±15 kV rating, and AEC-Q101 qualification in a 2.5 × 1.0 mm footprint-making it optimal for space-limited, high-speed automotive serial links requiring single-device coverage.

FAQ
What is the maximum operating temperature for PESD4USB3BBTBS-Q?
The device is rated for ambient temperatures from −55 °C to +150 °C and storage temperatures up to +150 °C. Its AEC-Q101 qualification confirms performance stability across this full automotive range, including thermal cycling and high-temperature reverse bias life testing.
Can PESD4USB3BBTBS-Q protect both USB 2.0 and USB 3.2 interfaces?
Yes-it supports both standards: its 0.23 pF capacitance and 3.3 V VRWM meet USB 2.0 signal integrity requirements, while its low dynamic resistance and fast snap-back response ensure effective clamping on USB 3.2 Gen1 (5 Gbps) differential lanes without introducing jitter or eye closure.
Why does the device have two separate GND pins (pins 3 and 8)?
These dedicated ground terminals provide independent, low-inductance return paths for the two protected differential pairs (CH1/CH2 and CH3/CH4), minimizing crosstalk and ensuring symmetrical clamping behavior. This separation reduces ground bounce and maintains common-mode rejection during multi-line ESD events.
Is side-wettable flank (SWF) soldering required for reliable assembly?
SWF is not mandatory but strongly recommended: the flanks enable automated optical inspection of solder joint quality-a critical requirement for automotive production. Standard reflow profiles work, but SWF ensures process control and zero-defect goals in safety-critical applications.
