Product details
Overview
PESD4USB5U-TBSAX from Nexperia is a unidirectional 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 discharge protection, 0.5 pF channel capacitance, 0.4 Ω dynamic resistance, 5 V reverse standoff voltage, and AEC-Q101 qualification for automotive infotainment and camera links.
For engineers reviewing the PESD4USB5U-TBSAX datasheet, PESD4USB5U-TBSAX pinout, PESD4USB5U-TBSAX application, or PESD4USB5U-TBSAX equivalent, key selection criteria include low-capacitance multi-channel ESD clamping for signal integrity preservation, side-wettable flank (SWF) DFN2510D-10 package compatibility with AOI, and snap-back clamping behavior enabling robust system-level protection without signal degradation on differential high-speed buses.
Technical Context
This device implements a deep snap-back clamping structure with negative dynamic resistance, reducing clamping voltage under ESD stress while maintaining ultra-low 0.4 pF capacitance per channel at 1 MHz. Its bidirectional transient response is engineered for symmetric positive/negative pulse handling (±15 kV IEC 61000-4-2, ±14 kV ISO 10605).
The DFN2510D-10 (SOT1176D) package features 0.5 mm pitch, side-wettable flanks for automated optical inspection, and matched 0.5 mm trace spacing - all optimized to minimize parasitic inductance and preserve impedance continuity on 10 Gbps differential lanes such as USB 3.2 Gen 2 and GMSL.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV per IEC 61000-4-2 level 4 (contact); ensures compliance with industrial and automotive system-level ESD immunity requirements |
| Channel Capacitance | 0.5 pF @ 1 MHz, 0 V - preserves signal integrity on 10 Gbps USB 3.2 and HDMI 2.0 differential pairs |
| Dynamic Resistance | 0.4 Ω @ 10 A TLP pulse - enables low-voltage clamping during fast ESD transients to protect downstream PHYs |
| Reverse Standoff Voltage | 5 V - compatible with 3.3 V and 5 V high-speed interface supply rails without leakage or conduction |
| Breakdown Voltage | 6–9 V @ 1 mA - provides sufficient margin above 5 V VRWM to avoid false triggering during normal operation |
| AEC-Q101 Qualified | Qualified for automotive applications - supports deployment in infotainment head units, ADAS cameras, and display modules |
Pinout & Package
Encapsulated in a leadless DFN2510D-10 (SOT1176D) plastic package measuring 2.5 mm × 1.0 mm × 0.75 mm with side-wettable flanks for AOI-compatible reflow soldering and 0.5 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 | CH2 | ESD protection anode for second differential pair (e.g., HDMI TMDS0+/−) |
| 3 | GND | Common cathode return path for all four channels; must be low-inductance connection to system ground plane |
| 4 | CH3 | ESD protection anode for third differential pair (e.g., DisplayPort AUX+/− or eSATA) |
| 5 | CH4 | ESD protection anode for fourth differential pair (e.g., GMSL SerDes data lane) |
| 6–10 | n.c. | No internal connection; electrically isolated terminals - no PCB routing required |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.5 pF per channel - minimizes insertion loss and maintains >10 GHz bandwidth for USB 3.2 Gen 2 and HDMI 2.0 signals |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.6 pF typical capacitance; 5.5 V VRWM; ±12 kV IEC 61000-4-2; no AEC-Q101 qualification | Targeted at consumer USB 3.0/PCIe; not certified for automotive temperature or reliability stress | Select when cost sensitivity outweighs automotive qualification and 0.1 pF extra capacitance is acceptable |
| SP3205-01UTG | 0.35 pF typical capacitance; 5.5 V VRWM; ±15 kV IEC 61000-4-2; AEC-Q101 qualified; 6-pin SOT-563 package | Limited to two channels; requires dual placement for four-lane protection; higher board area usage | Select when lowest possible capacitance is critical and layout allows discrete dual-channel implementation |
Compared with TPD4E05U06DQAR and SP3205-01UTG, PESD4USB5U-TBSAX uniquely combines four-channel integration, AEC-Q101 qualification, 0.5 pF capacitance, and SWF-enabled manufacturability in a single 2.5 mm × 1.0 mm footprint - making it optimal for space-constrained automotive SerDes and USB 3.2 Gen 2 designs requiring full production traceability.

FAQ
What is the maximum operating temperature for PESD4USB5U-TBSAX?
The device supports ambient temperatures from −55 °C to +150 °C and junction temperatures up to +150 °C, meeting AEC-Q101 thermal stress requirements for under-hood and display module applications. Its thermal performance is validated across the full range using JEDEC JESD51-1 compliant testing.
Does PESD4USB5U-TBSAX require external biasing or control signals?
No - it operates passively as a clamping diode array with no external power, enable, or configuration pins. The device relies solely on its intrinsic snap-back characteristics to conduct during ESD transients, returning to high-impedance state automatically after event clearance.
Can PESD4USB5U-TBSAX be used on bidirectional high-speed buses like USB 2.0?
Yes - although unidirectional in construction, its symmetrical clamping behavior (±3.5 V typical VCL at ±5 A) makes it effective for USB 2.0 D+/D− lines. It is explicitly listed in Nexperia's documentation for USB 2.0 system-level ESD protection alongside SuperSpeed USB 3.2.
How does the side-wettable flank (SWF) feature improve manufacturing yield?
The SWF design enables automated optical inspection of solder joint fillets on all 10 terminals without X-ray, detecting voids, insufficient wetting, or bridging in real time. This reduces post-reflow rework rates by >40% in high-volume automotive PCB assembly compared to non-SWF DFN packages.
