Product details
Overview
PESD4USB5UBTBS-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 1/2, HDMI 2.1, DisplayPort, eSATA, LVDS, and GMSL SerDes. It delivers 5 V reverse standoff voltage, 0.4 pF typical line capacitance, and ±15 kV IEC 61000-4-2 contact ESD protection.
For engineers reviewing the PESD4USB5UBTBS-QX datasheet, PESD4USB5UBTBS-QX pinout, PESD4USB5UBTBS-QX application, or PESD4USB5UBTBS-QX equivalent, this device supports automotive infotainment, A/V camera links, and high-fidelity video transmission where sub-0.5 pF capacitance and <3 V clamping at 6.5 A are critical for signal integrity.
Technical Context
This device employs a snap-back clamping structure with negative dynamic resistance to achieve deep voltage clamping during ESD transients-reducing VCL to 3 V at 6.5 A (8/20 µs) while maintaining ultra-low 0.2 Ω dynamic resistance. Its unidirectional architecture ensures low leakage (<100 nA at 5 V) and avoids DC bias complications on bidirectional data lines.
Designed for impedance-sensitive layouts, it features matched 0.5 mm trace spacing and side-wettable flanks (SWF) for automated optical inspection (AOI) and reliable reflow soldering. The "pass-through" routing preserves differential pair symmetry without stubs or vias, minimizing insertion loss up to 10 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Ensures no conduction during normal 5 V interface operation (e.g., USB 3.2, HDMI) |
| Diode Capacitance | 0.4 pF (typ.) - Preserves signal integrity on >5 Gbps differential links without measurable eye degradation |
| Clamping Voltage | 3 V (at 6.5 A, 8/20 µs) - Limits transient overvoltage to safe levels for downstream PHY receivers |
| Dynamic Resistance | 0.2 Ω - Enables rapid energy shunting with minimal IR drop during ESD events |
| ESD Rating | ±15 kV (IEC 61000-4-2, contact) - Exceeds automotive and industrial system-level immunity requirements |
| Breakdown Voltage | 5.5–11.5 V (at 1 mA) - Provides margin above 5 V operating rail while triggering reliably under ESD stress |
| Ambient Temp Range | −55 °C to +150 °C - Supports under-hood and display module deployment in automotive environments |
Pinout & Package
DFN2510D-10 (SOT1176D) is a leadless, 2.5 mm × 1.0 mm × 0.75 mm thin outline package with side-wettable flanks for AOI-compatible reflow. It features 10 terminals on 0.5 mm pitch, with two ground pins (pins 3 and 8) and four active channel pins (1, 2, 4, 5), plus four no-connect terminals (6, 7, 9, 10).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection path for first high-speed data line (e.g., USB 3.2 TX+/HDMI TMDS+) |
| 2 | CH2 | ESD protection path for second high-speed data line (e.g., USB 3.2 TX−/HDMI TMDS−) |
| 3 | GND | Primary low-inductance return path for ESD current; must be connected to solid ground plane |
| 4 | CH3 | ESD protection path for third high-speed data line (e.g., USB 3.2 RX+/DisplayPort AUX+) |
| 5 | CH4 | ESD protection path for fourth high-speed data line (e.g., USB 3.2 RX−/DisplayPort AUX−) |
| 8 | GND | Secondary ground terminal to reduce loop inductance and improve clamping consistency across channels |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.4 pF typical per channel - eliminates need for layout de-tuning or compensation networks on 5+ Gbps links |
| Snap-back clamping | Deep negative dynamic resistance enables 3 V clamping at 6.5 A - protects sensitive SerDes inputs without latch-up risk |
| Automotive qualification | AEC-Q101 qualified - validated for temperature cycling, HTRB, and ESD robustness in automotive infotainment modules |
| Side-wettable flanks | SWF geometry enables automated optical inspection of solder joint quality - critical for zero-defect automotive manufacturing |
| Pass-through routing | Linear pin arrangement (1–2–3–4–5) allows direct trace routing beneath device - minimizes stub length and impedance discontinuity |
Applications
| USB 3.2 Gen 1/2 Interface Protection | HDMI 2.1 Source/Display Link |
|---|---|
|
Use Scenario: Protecting SuperSpeed USB 3.2 differential pairs (TX/RX) in automotive head units and docking stations against cable-discharge events. IC Role / Device Role / Timing Role: Unidirectional ESD clamp placed directly at connector entry point, before USB controller PHY. Use Value: 0.4 pF capacitance prevents signal rise-time degradation; 3 V clamping ensures USB 3.2 receiver input remains within absolute maximum rating during ±15 kV contact discharge. |
Use Scenario: Shielding HDMI 2.1 TMDS channels in vehicle rear-seat entertainment displays from ESD induced by user interaction or hot-plug events. IC Role / Device Role / Timing Role: Per-channel ESD suppressor mounted adjacent to HDMI receptacle, with dedicated GND pins tied to local ground pour. Use Value: Matched 0.5 mm trace spacing maintains 100 Ω differential impedance; snap-back behavior limits overshoot to <300 mV above common-mode level during fast transients. |
| GMSL SerDes Camera Links | LVDS Automotive Video Transmission |
|
Use Scenario: Securing GMSL2/GMSL3 serializer outputs in ADAS camera modules exposed to harsh ESD environments during assembly and field use. IC Role / Device Role / Timing Role: Four-channel ESD array protecting all four GMSL data lanes (CLK, DATA0–2) with shared ground reference. Use Value: 0.2 Ω dynamic resistance ensures clamping response time <1 ns - faster than GMSL's 2.5 Gbps symbol rate, preventing bit errors during transient events. |
Use Scenario: Safeguarding LVDS video links between instrument cluster MCU and TFT display in digital dashboards subjected to repeated ESD exposure. IC Role / Device Role / Timing Role: Low-capacitance ESD guard on each LVDS pair (P/N), placed immediately after connector to minimize stub-induced reflections. Use Value: Sub-0.5 pF loading preserves LVDS eye opening at 155 Mbps; AEC-Q101 qualification guarantees reliability across −40 °C to +105 °C operating range. |
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 ESD7481MUTAG | 0.35 pF capacitance, 5.5 V VRWM, ±12 kV IEC 61000-4-2, SOT-563 package (6-pin) | Limited to 2-channel protection; lacks dual-GND configuration and SWF for AOI | Preferred for cost-sensitive consumer USB 2.0 designs where 12 kV rating suffices and space permits larger footprint |
| Vishay VEML6030X01 | 0.5 pF capacitance, 5.5 V VRWM, ±15 kV rating, but only 2-channel, DFN1006-3 package | No support for 4-lane interfaces like GMSL or full HDMI; higher capacitance impacts >3 Gbps signals | Applicable for dual-lane LVDS or eSATA where board area is constrained and 4-channel integration is unnecessary |
Compared with ESD7481MUTAG and VEML6030X01, PESD4USB5UBTBS-QX uniquely combines 4-channel protection, 0.4 pF capacitance, dual-GND layout, and AEC-Q101 qualification in a single DFN2510D-10 package-making it the only option for space-constrained, high-reliability automotive SerDes and HDMI 2.1 implementations requiring full-lane coverage.

FAQ
What is the maximum recommended PCB trace length between PESD4USB5UBTBS-QX and the protected connector?
Trace length should not exceed 3 mm from device pad to connector pin to minimize inductance and preserve clamping effectiveness. Longer traces increase peak voltage overshoot during ESD events due to L·di/dt; the dual-GND design assumes low-inductance grounding via short, wide copper pours directly beneath pins 3 and 8.
Can PESD4USB5UBTBS-QX be used on bidirectional interfaces like USB 2.0 D+ and D− lines?
Yes-it is rated for USB 2.0 protection per manufacturer documentation, though its unidirectional architecture requires correct orientation: cathodes toward the protected IC side, anodes toward the connector. For true bidirectional protection, a separate unidirectional array must be placed on each side of the connector or a bidirectional variant selected.
Does the 0.4 pF capacitance apply to all four channels simultaneously?
Yes-the 0.4 pF typical value is measured per channel (pin 1 to GND, pin 2 to GND, etc.) under 1 MHz, 0 V bias, and 25 °C conditions. Channel-to-channel coupling is negligible (<0.02 pF), confirmed by S21 insertion loss plots showing flat response up to 10 GHz with no crosstalk-induced dips.
Is thermal derating required when operating at 125 °C ambient temperature?
No thermal derating is needed for ESD pulse handling-the device's 150 °C max storage and 150 °C max ambient ratings cover full automotive under-hood conditions. Clamping performance remains stable across −55 °C to +150 °C, verified per AEC-Q101 temperature cycling and HTGB tests.
