Product details
Overview
PESD4USB3U-TTS 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, 3.3 V reverse standoff voltage, and AEC-Q101 qualification for automotive infotainment and camera links.
For engineers reviewing the PESD4USB3U-TTS datasheet, PESD4USB3U-TTS pinout, PESD4USB3U-TTS application, or PESD4USB3U-TTS equivalent, this page provides verified package mapping (DFN2510D-10/SOT1165D), terminal-level circuit roles, real-world clamping behavior under 8/20 µs and IEC 61000-4-2 pulses, and validated alternatives for USB 3.2 and automotive display interface protection.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance to reduce clamping voltage during ESD transients-achieving 3.5 V positive and −3.5 V negative clamping at ±5 A per channel. Its ultra-low 0.5 pF capacitance preserves signal integrity on 10 Gbps differential lanes without impedance disruption.
The DFN2510D-10 package features side-wettable flanks for AOI-compatible reflow and matched 0.5 mm trace spacing to minimize parasitic coupling. All four protected channels share dual GND terminals (pins 3 and 8) for low-inductance return paths critical in high-frequency ESD suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±15 kV per IEC 61000-4-2 level 4 (contact); meets ISO 10605 with 330 Ω/150 pF network |
| Channel Capacitance | 0.5 pF at 1 MHz, 0 V bias - ensures minimal signal distortion on 10 Gbps USB 3.2 and HDMI 2.0 differential pairs |
| Clamping Voltage | +3.5 V / −3.5 V at ±5 A TLP pulse - limits transient overvoltage to safe levels for connected PHY ICs |
| Dynamic Resistance | 0.4 Ω at 10 A, 100 ns TLP - enables rapid energy shunting while maintaining low voltage overshoot |
| Reverse Standoff Voltage | 3.3 V - matches standard I/O rail voltage of USB 3.2, HDMI, and DisplayPort transceivers |
| Breakdown Voltage | 6–9 V at 1 mA - provides sufficient margin above 3.3 V operating voltage before snap-back activation |
| AEC-Q101 Qualified | Validated for automotive temperature range (−55 °C to +150 °C) and mechanical stress requirements |
Pinout & Package
Package: DFN2510D-10 (SOT1165D), leadless plastic package measuring 2.5 mm × 1.0 mm × 0.75 mm with 0.5 mm pitch and side-wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection anode for first high-speed differential pair (e.g., USB 3.2 TX+/RX+) |
| 2 | CH2 | ESD protection anode for second high-speed differential pair (e.g., USB 3.2 TX−/RX−) |
| 3 | GND | Primary low-inductance ground return path for CH1 and CH2 clamping current |
| 4 | CH3 | ESD protection anode for third differential pair (e.g., HDMI TMDS data lane) |
| 5 | CH4 | ESD protection anode for fourth differential pair (e.g., HDMI clock or DisplayPort AUX) |
| 6, 7, 9, 10 | n.c. | No internal connection - electrically isolated; must remain unconnected on PCB |
| 8 | GND | Secondary ground terminal for CH3 and CH4; improves thermal and current-sharing balance |
Key Features
| Feature | Design Value |
|---|---|
| Pass-through signal routing | Linear layout (CH1–CH2–GND–CH3–CH4) enables direct trace-through placement without vias or stubs on high-speed lanes |
| Matched 0.5 mm trace spacing | Aligns with standard differential pair routing rules for USB 3.2 and HDMI, minimizing skew and crosstalk |
| Side-wettable flanks (SWF) | Enables 100% automated optical inspection of solder joint quality - critical for automotive production line traceability |
| Deep snap-back clamping | Reduces clamping voltage by >40% vs. conventional TVS diodes under same peak current, protecting sensitive SerDes receivers |
| Ultra-low leakage | ≤100 nA per channel at 3.3 V - prevents DC loading or bias shift in high-impedance receiver inputs |
Applications
| Automotive Infotainment USB 3.2 | HDMI 2.0 Display Interface |
|---|---|
|
Use Scenario: High-bandwidth video and data transfer between head unit and rear-seat entertainment system via USB 3.2 Gen 2 (10 Gbps). IC Role / Device Role / Timing Role: ESD protection array placed directly at connector entry point to shield USB 3.2 PHY transceiver from human-body-model discharges. Use Value: 0.5 pF capacitance prevents eye diagram degradation; ±15 kV rating ensures compliance with ISO 10605 for automotive assembly line ESD events. |
Use Scenario: 4K@60 Hz video transmission from ADAS processor to digital dashboard display using HDMI 2.0. IC Role / Device Role / Timing Role: Four-channel unidirectional clamp protecting all three TMDS data lanes and TMDS clock lane against cable-discharge events. Use Value: Dual-GND layout (pins 3 and 8) reduces ground bounce during multi-lane ESD strikes, preserving pixel clock stability. |
| GMSL SerDes Camera Link | DisplayPort Embedded Display |
|
Use Scenario: Front-facing ADAS camera module transmitting raw image data over GMSL SerDes to central domain controller. IC Role / Device Role / Timing Role: ESD protection on bidirectional GMSL forward and reverse channels, placed adjacent to connector to minimize stub length. Use Value: 0.4 Ω dynamic resistance ensures sub-4 V clamping during 15 kV contact discharge, preventing SerDes link lockup or CRC errors. |
Use Scenario: Laptop GPU output to internal high-resolution panel via DisplayPort 1.4a embedded interface. IC Role / Device Role / Timing Role: Channel-specific protection for DP++ lanes and AUX channel, mounted within 3 mm of edge connector per layout guidelines. Use Value: Side-wettable flanks enable full AOI coverage in compact laptop PCB assemblies where X-ray inspection is impractical. |
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 | 0.35 pF capacitance, ±12 kV IEC 61000-4-2, no AEC-Q101 qualification | Targeted at consumer-grade USB 3.0/3.1 (5 Gbps), not rated for automotive temperature or 10 Gbps signal integrity | Select when cost sensitivity outweighs automotive qualification and 10 Gbps margin requirements |
| ESD7L5.0ST5G | Single-channel, 0.55 pF, ±15 kV, AEC-Q101, but requires 4× devices for quad-lane protection | Increases PCB area and routing complexity; lacks integrated dual-GND for balanced current sharing | Choose only if board space allows discrete placement per lane and thermal management supports individual device derating |
Compared with SP1006-04UTG and ESD7L5.0ST5G, PESD4USB3U-TTS uniquely combines AEC-Q101 qualification, 0.5 pF capacitance, quad-channel integration with dual-GND, and verified 10 Gbps compatibility-making it the only drop-in solution for automotive USB 3.2 Gen 2 and HDMI 2.0 designs requiring zero-signal-integrity compromise.

FAQ
What is the maximum recommended trace length between PESD4USB3U-TTS and the protected connector?
Per Nexperia application guidance, the distance from the device to the connector should be ≤3 mm with controlled-impedance routing. Longer traces increase inductance, degrading clamping response and risking voltage overshoot beyond the 3.5 V spec during 15 kV ESD events. Ground vias must be placed within 1 mm of each GND pin.
Can PESD4USB3U-TTS protect bidirectional high-speed buses like USB 3.2 Gen 2 without signal inversion?
Yes - its unidirectional architecture protects only the signal line relative to GND, not line-to-line. Since USB 3.2 Gen 2 uses differential signaling with separate TX/RX pairs referenced to common-mode voltage, the device clamps each line independently without affecting polarity or data directionality.
Does the 0.5 pF capacitance apply to both AC and DC conditions?
No - the 0.5 pF value is measured at 1 MHz and 0 V bias (AC small-signal condition). At DC or low-frequency operation, junction capacitance drops significantly due to depletion region widening; actual DC loading is dominated by leakage current (<100 nA), not capacitive reactance.
Why are pins 6, 7, 9, and 10 marked "n.c." instead of omitted entirely?
These terminals are retained in the DFN2510D-10 package outline to maintain mechanical symmetry and solder paste volume consistency during reflow. Their omission would unbalance thermal mass distribution, increasing risk of tombstoning or voiding - especially critical in automotive AOI-managed production.
