Product details
Overview
PESD4USB3UBTTS-Q from Nexperia is a unidirectional ESD protection diode array in DFN2510D-10 (SOT1165D) package, designed for high-speed serial interfaces including SuperSpeed USB 3.2, HDMI 2.1, DisplayPort, eSATA, LVDS, and GMSL SerDes. It delivers 3.3 V reverse standoff voltage, 0.4 pF typical line capacitance, ±15 kV IEC 61000-4-2 level 4 ESD immunity, and 0.2 Ω dynamic resistance for low-clamping protection in automotive infotainment and camera links.
For engineers reviewing the PESD4USB3UBTTS-Q datasheet, PESD4USB3UBTTS-Q pinout, PESD4USB3UBTTS-Q application, or PESD4USB3UBTTS-Q equivalent, key selection criteria include ultra-low capacitance for signal integrity, AEC-Q101 qualification for automotive reliability, matched 0.5 mm trace spacing for AOI compatibility, and pass-through routing for minimal PCB layout impact on high-speed differential pairs.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance to reduce clamping voltage during ESD transients-achieving 2.9 V clamping at 6.5 A (8/20 µs) while maintaining sub-0.5 pF capacitance per channel at 1 MHz and 0 V bias. Its unidirectional architecture supports DC-biased high-speed data lines without forward conduction risk under normal operation.
The DFN2510D-10 package features side-wettable flanks (SWF) for automated optical inspection and 0.5 mm pitch terminals aligned for differential pair routing. Four active channels (CH1–CH4) share dual ground pins (pins 3 and 8), with six terminals unused (pins 6, 7, 9, 10), enabling compact placement adjacent to connectors or IC I/O pads.
Key Specifications

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 | 0.5 pF capacitance, 3.3 V VRWM, ±12 kV IEC 61000-4-2, SOD-323 package | Smaller 2-channel count; lacks AEC-Q101 qualification and SWF | Preferred for cost-sensitive consumer USB 2.0 ports where automotive qualification is not required |
| TPD4E05U06DQAR | 0.5 pF capacitance, 5.5 V VRWM, ±12 kV IEC 61000-4-2, X2SON-8 package | Higher VRWM limits use on 3.3 V rails; no AEC-Q101 rating | Suitable for industrial HDMI 2.0 interfaces with 5 V bias, but not for automotive USB 3.2 due to voltage mismatch and qualification gap |
Compared with SP1006-04UTG and TPD4E05U06DQAR, PESD4USB3UBTTS-Q uniquely combines AEC-Q101 qualification, 0.4 pF capacitance, four-channel integration, and side-wettable flanks-making it the only option validated for production automotive SerDes links requiring zero-signal-integrity compromise and full-process traceability.

FAQ
What is the maximum recommended trace length between PESD4USB3UBTTS-Q and the protected connector?
Trace length should be ≤3 mm from each channel pin to its corresponding connector pad to minimize inductance and preserve clamping effectiveness. Longer traces increase peak voltage overshoot during ESD events-verified via TLP testing showing >15% VCL rise at 5 mm trace length. Ground vias must be placed within 1 mm of pins 3 and 8 to maintain low-inductance return paths.
Can PESD4USB3UBTTS-Q be used on bidirectional data lines like USB 2.0 D+/D−?
No-it is unidirectional and rated for 3.3 V reverse standoff, making it unsuitable for bidirectional 3.3 V-tolerant lines that swing negative during data transitions. For USB 2.0, Nexperia recommends the bidirectional PESD5V0S1BA (5 V VRWM) or PESD2CAN (12 V VRWM), both qualified for ±15 kV ESD and compatible with full-swing signaling.
Does the device require external biasing or control signals?
No-PESD4USB3UBTTS-Q operates passively with no external power, bias, or enable signals. It functions solely as a voltage-triggered clamp: conducting only during ESD transients exceeding breakdown voltage (5.5–11.5 V), remaining fully transparent (<100 nA leakage at 3.3 V) during normal operation.
How does the snap-back behavior affect system-level reliability during repeated ESD events?
Snap-back enables lower clamping voltage but requires strict adherence to datasheet limits: repeated exposure above 3.3 V DC or AC bias risks unintended triggering. Testing confirms stable performance over 1000+ ESD pulses at ±15 kV when used within specified VRWM and ambient temperature (−55 °C to +150 °C), with no parameter shift beyond ±5%.
