Product details
Overview
PESD4USB3UBTBS-QX from Nexperia is a unidirectional ESD protection diode array in DFN2510D-10 (SOT1176D) package, designed for high-speed serial interfaces including USB 3.2 Gen 1, HDMI 2.1, DisplayPort, eSATA, LVDS, and GMSL SerDes. It delivers 3.3 V reverse standoff voltage, 0.4 pF typical line capacitance, and ±15 kV IEC 61000-4-2 contact discharge protection.
For engineers reviewing the PESD4USB3UBTBS-QX datasheet, PESD4USB3UBTBS-QX pinout, PESD4USB3UBTBS-QX application, or PESD4USB3UBTBS-QX equivalent, this device is selected for automotive infotainment, A/V camera links, and high-fidelity signal integrity-critical data lines where sub-0.5 pF loading and snap-back clamping under 3 V are mandatory.
Technical Context
This device implements a deep snap-back clamping structure with 0.2 Ω dynamic resistance, enabling low-voltage clamping (VCL ≤ 3 V at 6.5 A, 8/20 µs) while maintaining ultra-low capacitance across four independent channels. Its unidirectional architecture supports DC-biased high-speed differential pairs without forward conduction during normal operation.
Qualified to AEC-Q101 and packaged in a side-wettable flank (SWF) DFN2510D-10, it enables automated optical inspection (AOI) and robust reflow soldering on automotive PCBs. The matched 0.5 mm trace spacing and pass-through routing minimize impedance discontinuity on 5–10 Gbps serial lanes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V reverse standoff voltage - ensures no leakage or conduction during normal 3.3 V interface operation |
| Cd | 0.4 pF typical capacitance at 1 MHz - preserves signal integrity on >5 Gbps USB 3.2 and HDMI 2.1 links |
| VCL | ≤3 V clamping voltage at 6.5 A, 8/20 µs - limits transient overvoltage seen by downstream PHY |
| Rdyn | 0.2 Ω dynamic resistance - enables rapid energy shunting with minimal IR drop during ESD events |
| ESD Rating | ±15 kV IEC 61000-4-2 contact discharge - exceeds automotive system-level immunity requirements |
| Breakdown Voltage | 5.5–11.5 V (VBR at 1 mA) - provides margin above VRWM while enabling fast snap-back initiation |
| Leakage Current | ≤100 nA at 3.3 V - prevents DC loading and bias shift on sensitive receiver inputs |
Pinout & Package
DFN2510D-10 (SOT1176D) package: leadless, 2.5 mm × 1.0 mm × 0.75 mm body, 0.5 mm pitch, side-wettable flanks for AOI-compatible reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection channel for first high-speed differential pair (e.g., USB3 TX+/−) |
| 2 | CH2 | ESD protection channel for second differential pair (e.g., USB3 RX+/−) |
| 3 | GND | Dedicated ground return path for CH1/CH2 clamping current |
| 4 | CH3 | ESD protection channel for third differential pair (e.g., HDMI TMDS0+/−) |
| 5 | CH4 | ESD protection channel for fourth differential pair (e.g., HDMI TMDS1+/−) |
| 6, 7, 9, 10 | n.c. | No internal connection - electrically isolated, may be left floating or tied to GND per layout |
| 8 | GND | Second dedicated ground terminal for CH3/CH4 - reduces shared-impedance coupling |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.4 pF typical per channel - avoids signal attenuation and jitter on SuperSpeed USB and HDMI 2.1 |
| Snap-back clamping | 0.2 Ω dynamic resistance - sustains low clamping voltage (<3 V) even at 6.5 A peak pulse |
| Automotive qualification | AEC-Q101 qualified - validated for temperature cycling, HTRB, and ESD stress in automotive environments |
| Side-wettable flanks | SOT1176D package with SWF - enables reliable AOI inspection of solder joint quality on bottom terminals |
| Pass-through routing | Linear pin arrangement (1–5, 8) - allows direct trace routing through protected channels without vias or stubs |
Applications
| Infotainment USB/HDMI Interface | Automotive Camera Link (GMSL) |
|---|---|
|
Use Scenario: Protecting USB 3.2 Gen 1 and HDMI 2.1 ports in vehicle head units and rear-seat entertainment systems against ESD during cable insertion and handling. IC Role / Device Role / Timing Role: Unidirectional ESD clamp placed directly at connector entry point, before retimer or level shifter. Use Value: 0.4 pF loading prevents eye diagram degradation at 5 Gbps; ±15 kV rating meets ISO 10605 automotive test requirements. |
Use Scenario: Shielding bidirectional GMSL SerDes links between ADAS cameras and domain controllers from ESD induced on long harnesses. IC Role / Device Role / Timing Role: Four-channel discrete ESD protection per link, installed adjacent to connector with matched trace lengths. Use Value: Dual GND pins (pins 3 and 8) minimize ground bounce between channels; snap-back behavior ensures <3 V clamping during fast transients. |
| DisplayPort Video Transmission | eSATA Data Storage Interface |
|
Use Scenario: Safeguarding DisplayPort 1.4a main link (HBR3, 8.1 Gbps) in automotive digital dashboards and central displays. IC Role / Device Role / Timing Role: Channel-specific protection on each of four DP lanes, with ground separation to prevent crosstalk. Use Value: Sub-0.5 pF capacitance maintains >12 dB insertion loss margin at 4 GHz; AEC-Q101 ensures reliability over 15-year vehicle life. |
Use Scenario: ESD hardening of external SATA interfaces in automotive telematics gateways and infotainment storage modules. IC Role / Device Role / Timing Role: Protection on both differential TX/RX pairs, mounted within 3 mm of eSATA receptacle. Use Value: 3.3 V VRWM aligns with eSATA PHY supply; 0.2 Ω Rdyn prevents voltage overshoot beyond receiver absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.5 pF typical capacitance; 3.6 V VRWM; 3.5 V VCL at 4 A | Higher clamping voltage and slightly higher capacitance - less suitable for >5 Gbps links | Select when lower cost and TI ecosystem support outweigh marginal signal integrity trade-offs |
| SP3205-01UTG | 0.35 pF typical capacitance; 3.3 V VRWM; 2.8 V VCL at 5 A; SOD-323 package | Single-channel, smaller package - requires four discrete devices vs. integrated quad solution | Select when board space permits discrete placement and tighter capacitance tolerance is critical |
Compared with TPD4E05U06DQAR and SP3205-01UTG, PESD4USB3UBTBS-QX uniquely combines quad-channel integration, 0.2 Ω dynamic resistance, and AEC-Q101 qualification in a single SWF-enabled DFN - reducing BOM count, improving thermal coupling, and simplifying AOI validation for automotive production.

FAQ
What is the maximum operating temperature range for PESD4USB3UBTBS-QX?
The device is rated for ambient operating temperatures from −55 °C to +150 °C and storage temperatures up to +150 °C, fully supporting under-hood and display module environments in automotive applications per AEC-Q101 qualification.
Can PESD4USB3UBTBS-QX protect bidirectional differential signals like USB 3.2 Gen 1?
Yes - its unidirectional configuration is applied per signal line (e.g., TX+ and TX− each use separate diodes), allowing full protection of bidirectional AC-coupled differential pairs without interfering with normal signal swing or DC bias conditions.
How does the snap-back behavior affect PCB layout design?
The snap-back characteristic requires strict avoidance of DC current sources on protected lines; layout must ensure no path exists for sustained current >10 mA after breakdown, otherwise the device may latch into low-resistance state and fail open-circuit during subsequent operation.
Is the DFN2510D-10 package compatible with standard reflow profiles?
Yes - the SOT1176D package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles with peak temperatures up to 260 °C; recommended stencil thickness is 0.1 mm per Nexperia footprint guidelines.
