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 Gen 1 (5 Gbps), HDMI 2.1, DisplayPort, eSATA, LVDS, and GMSL SerDes. It delivers ±15 kV IEC 61000-4-2 contact ESD protection, 0.4 pF typical line capacitance, and 0.2 Ω dynamic resistance to preserve signal integrity in automotive infotainment and camera links.
For engineers reviewing the PESD4USB5UBTTS-Q datasheet, PESD4USB5UBTTS-Q pinout, PESD4USB5UBTTS-Q application, or PESD4USB5UBTTS-Q equivalent, key selection criteria include sub-0.5 pF capacitance for >5 Gbps data rates, AEC-Q101 qualification for automotive deployment, matched 0.5 mm trace spacing for AOI compatibility, and snap-back clamping architecture enabling low VCL under 6.5 A 8/20 µs surge.
Technical Context
This device implements a deep snap-back clamping structure with negative dynamic resistance, reducing clamping voltage during ESD transients while maintaining ultra-low capacitance across all four protected channels. Its unidirectional configuration supports 5 V DC bias rails with 5.5 V minimum breakdown voltage and <100 nA reverse leakage at VRWM.
The DFN2510D-10 package features side-wettable flanks (SWF) for automated optical inspection and 'pass-through' routing that preserves controlled impedance on high-speed differential pairs. It is qualified per AEC-Q101 and rated for operation from −55 °C to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V reverse standoff voltage - ensures no conduction during normal 5 V interface operation |
| Cd (typ) | 0.4 pF at 1 MHz - minimizes signal distortion on SuperSpeed USB 3.2 and HDMI 2.1 links |
| VBR (min) | 5.5 V at 1 mA - provides margin above 5 V rail while enabling fast ESD turn-on |
| Rdyn | 0.2 Ω - achieves low clamping voltage (VCL ≤ 2.9 V at 6.5 A) during ESD events |
| ESD Rating | ±15 kV IEC 61000-4-2 contact - exceeds Level 4 immunity for automotive and industrial environments |
| Package | DFN2510D-10 (SOT1165D), 2.5 × 1.0 × 0.75 mm - enables compact layout with AOI-compatible side-wettable flanks |
| Ambient Temp | −55 °C to +150 °C - supports under-hood and display module placement in automotive systems |

Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.4 pF typical per channel - preserves signal rise/fall times and eye diagram integrity on 5 Gbps+ links |
| Snap-back clamping | Dynamic resistance of 0.2 Ω - reduces clamping voltage to ≤2.9 V at 6.5 A, protecting downstream PHYs |

| Pass-through routing | Linear pin arrangement (CH1–CH2–GND–CH3–CH4) - simplifies PCB trace routing without vias or stubs |
Applications
| USB 3.2 Gen 1 Interface Protection | HDMI 2.1 Source Port Protection |
|---|---|
|
Use Scenario: Protecting USB 3.2 Gen 1 (5 Gbps) differential pairs in automotive head unit host controllers against ESD during cable insertion. IC Role / Device Role / Timing Role: Unidirectional ESD clamp placed directly at connector, shunting transient current to dual GND pins before reaching USB PHY. Use Value: 0.4 pF capacitance prevents signal degradation; 0.2 Ω Rdyn limits clamping voltage to ≤2.9 V, avoiding PHY latch-up or damage. |
Use Scenario: Shielding HDMI 2.1 TMDS channels in vehicle rear-seat entertainment displays from ESD during hot-plug events. IC Role / Device Role / Timing Role: Four-channel ESD suppressor mounted adjacent to HDMI receptacle, with matched trace lengths to maintain differential skew <10 ps. Use Value: Dual GND pins (pins 3 and 8) reduce ground inductance; 15 kV ESD rating meets ISO 10605 requirements for automotive cabin environments. |
| GMSL SerDes Camera Link Protection | eSATA Interface Protection |
|
Use Scenario: Safeguarding GMSL serializer outputs in ADAS front cameras exposed to ESD during assembly or field service. IC Role / Device Role / Timing Role: Channel-specific ESD protection on serialized video lanes, placed within 3 mm of connector per AEC-Q200 layout guidelines. Use Value: −55 °C to +150 °C operating range supports under-hood camera modules; snap-back behavior avoids DC latch-up during transient overvoltage. |
Use Scenario: Securing external SATA ports in automotive infotainment gateways against ESD from user-connected storage devices. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional diode array applied to eSATA differential pair, leveraging low capacitance to retain 3 Gbps signal fidelity. Use Value: 5 V VRWM aligns with eSATA power delivery; 0.5 mm pitch and SWF enable reliable reflow in high-volume automotive PCB assembly. |
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 NUF4302MUTAG | 0.55 pF typical capacitance; 8 kV IEC 61000-4-2; SOT-363 package (larger footprint, no SWF) | Limited to USB 2.0 and lower-speed LVDS due to higher capacitance and lower ESD rating | Select when cost sensitivity outweighs 5 Gbps support and automotive qualification is not required. |
| Vishay VEML6075-GG1 | UV sensor IC - not an ESD protector; incompatible function and package | Not applicable - functional mismatch | Exclude from ESD protection evaluation; this is a photodiode-based UV index sensor. |
Compared with NUF4302MUTAG, PESD4USB5UBTTS-Q delivers 25% lower capacitance, 88% higher ESD rating, and AEC-Q101 qualification in a smaller, AOI-optimized package - making it the only viable choice for automotive USB 3.2 and HDMI 2.1 designs requiring production-grade reliability.

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 per AEC-Q200 guidelines. Longer traces increase inductance, raising clamping voltage during transients. The DFN2510D-10's side-wettable flanks and pass-through pinout support direct routing without vias, minimizing parasitic inductance and preserving <10 ps differential skew on USB 3.2 or HDMI links.
Can PESD4USB5UBTTS-Q be used on bidirectional interfaces like USB 2.0 D+ and D−?
Yes - although unidirectional, its 5 V VRWM and 5.5 V VBR allow safe use on 3.3 V or 5 V bidirectional data lines like USB 2.0. The device clamps only during negative ESD events on the cathode side; for full bidirectional protection, pair with a complementary device or verify system-level immunity per IEC 61000-4-2 testing with actual layout and grounding.
Does the 'n.c.' marking on pins 6, 7, 9, and 10 mean they must be left floating?
No - these pins are internally unconnected but may be tied to ground in PCB layout to improve thermal dissipation or mechanical stability. Doing so does not affect electrical performance. However, avoid routing high-speed signals near them, and ensure solder mask clearance matches the DFN2510D-10 footprint to prevent bridging during reflow.
How does the snap-back behavior impact DC bias stability on protected lines?
The snap-back structure triggers only during ESD transients exceeding VBR; under normal 5 V operation, reverse leakage remains <100 nA, posing no loading risk. However, sustained overvoltage (>5.5 V) could induce snap-back conduction - design must ensure no DC sources exceed VRWM, and avoid connecting unprotected battery rails directly to protected lines.
