Product details
Overview
PESD4USB3UTBS-QX 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 ESD 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 PESD4USB3UTBS-QX datasheet, PESD4USB3UTBS-QX pinout, PESD4USB3UTBS-QX application, or PESD4USB3UTBS-QX equivalent, key selection criteria include low-capacitance signal integrity preservation, snap-back clamping behavior for deep voltage suppression, side-wettable flanks for AOI-compatible DFN2510D-10 assembly, and automotive-grade reliability across four differential data lanes.
Technical Context
This device implements a multi-channel, unidirectional snap-back ESD clamp architecture optimized for bidirectional high-speed data lines. Each of its four protected channels exhibits sub-0.5 pF capacitance at 1 MHz and 0 V bias, with dynamic resistance stabilized at 0.4 Ω under 10 A TLP stress.
The DFN2510D-10 package integrates two ground terminals (Pins 3 and 8) and four active signal channels (CH1–CH4) in a 2.5 mm × 1.0 mm footprint with 0.5 mm pitch and side-wettable flanks-enabling automated optical inspection and thermal performance suitable for automotive A/V monitors and SerDes links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV per IEC 61000-4-2 level 4 (contact); ensures robust system-level immunity in automotive infotainment ports |
| Channel Capacitance | 0.5 pF typical at 1 MHz, 0 V - preserves signal integrity on 10 Gbps USB 3.2 and HDMI 2.0 differential pairs |
| Dynamic Resistance | 0.4 Ω at 10 A TLP pulse - enables ultra-low clamping voltage during fast ESD transients |
| Reverse Standoff Voltage | 3.3 V - matches standard I/O voltage rails for USB, HDMI, and LVDS interfaces without leakage risk |
| Breakdown Voltage | 6 V minimum at 1 mA - provides safe margin above 3.3 V operating rail while triggering reliably during ESD events |
| AEC-Q101 Qualified | Qualified per Automotive Electronics Council stress test standard - supports deployment in automotive display and camera modules |
Pinout & Package
Package: DFN2510D-10 (SOT1176D), leadless plastic package measuring 2.5 mm × 1.0 mm × 0.75 mm with 0.5 mm pitch and side-wettable flanks for AOI-compliant reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection input/output for first high-speed differential pair (e.g., USB 3.2 TX+/−) |
| 2 | CH2 | ESD protection input/output for second high-speed differential pair (e.g., USB 3.2 RX+/−) |
| 3 | GND | Primary ground reference for ESD current shunting; must be low-inductance PCB connection |
| 4 | CH3 | ESD protection input/output for third high-speed differential pair (e.g., HDMI TMDS data lane) |
| 5 | CH4 | ESD protection input/output for fourth high-speed differential pair (e.g., HDMI clock or DisplayPort AUX) |
| 6, 7, 9, 10 | n.c. | No internal connection; electrically isolated; may be left unconnected or tied to ground per layout requirements |
| 8 | GND | Secondary ground terminal for improved thermal dissipation and ESD current path symmetry |
Key Features
| Feature | Design Value |
|---|---|
| Matched 0.5 mm trace spacing + SWF | Enables AOI-compatible placement and automated post-solder inspection in high-volume automotive PCB assembly |
| Pass-through signal routing | Minimizes PCB trace discontinuity and impedance mismatch on differential pairs - critical for 10 Gbps eye diagram compliance |
| Deep snap-back clamping | Reduces clamping voltage under ESD stress by leveraging negative dynamic resistance, protecting downstream PHYs |
| Four independent channels | Supports full-lane protection of USB 3.2 Gen 2 (2-lane), HDMI 2.0 (3 data + 1 clock), or dual-link LVDS interfaces |
| AEC-Q101 qualification | Validates reliability under temperature cycling, humidity, and mechanical shock - required for front-end camera and center-stack displays |
Applications
| Automotive Infotainment USB Hub | HDMI 2.0 Display Interface |
|---|---|
Use Scenario: Protecting USB 3.2 Gen 2 upstream/downstream ports in vehicle head units against hot-plug ESD and cable discharge. IC Role / Device Role / Timing Role: Unidirectional ESD clamp placed directly at connector entry point, before USB controller PHY. Use Value: 0.5 pF capacitance prevents signal degradation at 10 Gbps; ±15 kV rating exceeds ISO 10605 automotive test requirements. |
Use Scenario: Shielding HDMI 2.0 TMDS data and clock lanes in digital dashboards and rear-seat entertainment systems. IC Role / Device Role / Timing Role: Four-channel ESD suppressor placed adjacent to HDMI receptacle, guarding all three data lanes and clock line. Use Value: Matched channel capacitance ensures <1% skew between differential pairs; AEC-Q101 qualification supports 15-year automotive service life. |
| GMSL SerDes Camera Link | LVDS Automotive Display Interface |
Use Scenario: Safeguarding GMSL serializer outputs in ADAS front/rear cameras exposed to harsh ESD environments during vehicle assembly and field use. IC Role / Device Role / Timing Role: ESD protection array installed at camera module flex PCB edge connector, prior to coaxial cable launch. Use Value: 0.4 Ω dynamic resistance limits clamping voltage to <6 V during 15 kV contact discharge - preserving GMSL signal fidelity and jitter budget. |
Use Scenario: Protecting LVDS video links between infotainment processor and TFT display in instrument clusters and center consoles. IC Role / Device Role / Timing Role: High-speed ESD suppressor placed inline on each LVDS differential pair, minimizing stub length. Use Value: Side-wettable flanks ensure solder joint integrity verification via AOI; 3.3 V VRWM aligns with LVDS I/O voltage domain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U4-2/TR | 0.65 pF channel capacitance; 3.6 V VRWM; ±12 kV IEC 61000-4-2; no AEC-Q101 qualification | Suitable for consumer USB/HDMI but not automotive due to lower ESD rating and lack of automotive qualification | Select when cost sensitivity outweighs automotive compliance and 10 Gbps signal integrity demands |
| TPD4E004DRYR | 0.5 pF capacitance; 3.6 V VRWM; ±12 kV IEC 61000-4-2; 0.55 Ω Rdyn; no AEC-Q101 | Validated for USB 2.0/3.0 and HDMI 1.4 but not rated for 10 Gbps USB 3.2 Gen 2 or automotive temperature range | Prefer for industrial non-automotive designs requiring low capacitance and TI supply chain alignment |
Compared with ES5V3U4-2/TR and TPD4E004DRYR, PESD4USB3UTBS-QX uniquely combines AEC-Q101 qualification, ±15 kV ESD rating, and 0.5 pF capacitance - making it the only option qualified for production automotive USB 3.2 Gen 2 and HDMI 2.0 interfaces requiring long-term reliability and 10 Gbps signal fidelity.

FAQ
What is the maximum data rate supported by PESD4USB3UTBS-QX?
PESD4USB3UTBS-QX is explicitly characterized and validated for SuperSpeed USB 3.2 Gen 2 operation at 10 Gbps, as confirmed in the product data sheet's General Description and Applications sections. Its 0.5 pF channel capacitance and matched trace layout minimize insertion loss and maintain signal integrity up to this rate.
Does PESD4USB3UTBS-QX support bidirectional signal lines?
Yes - although unidirectional in diode polarity, PESD4USB3UTBS-QX protects bidirectional high-speed differential signals (e.g., USB 3.2, HDMI, LVDS) by clamping both positive and negative ESD transients to ground via its snap-back structure, as verified in Figures 5–8 of the datasheet showing symmetric ±3.5 V clamping.
Can Pin 6, Pin 7, Pin 9, and Pin 10 be grounded on the PCB?
Yes - Pins 6, 7, 9, and 10 are explicitly marked "n.c." (not connected) in Table 1 of the datasheet. They have no internal bond wire or silicon connection and may be left floating or tied to ground for mechanical stability or thermal relief, provided no unintended coupling occurs.
Is PESD4USB3UTBS-QX compatible with lead-free reflow profiles?
Yes - the DFN2510D-10 (SOT1176D) package is qualified for standard lead-free reflow soldering per JEDEC J-STD-020. Figure 10 in the datasheet provides the recommended footprint and stencil thickness (0.1 mm), and the device withstands peak temperatures up to 260 °C for ≤60 seconds.
