Product details
Overview
PESD4USB3U-TBSAX 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, and 0.4 Ω dynamic resistance in a DFN2510D-10 (SOT1176D) package with side-wettable flanks for AOI compatibility.
For engineers reviewing the PESD4USB3U-TBSAX datasheet, PESD4USB3U-TBSAX pinout, PESD4USB3U-TBSAX application, or PESD4USB3U-TBSAX equivalent, key selection criteria include low-capacitance bidirectional signal integrity preservation, AEC-Q101 qualification for automotive infotainment, and matched 0.5 mm trace spacing for high-density PCB routing near differential pairs.
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 0.4–0.5 pF capacitance ensures minimal signal distortion on 10 Gbps USB 3.2 and HDMI 2.0 differential lanes.
Rated for 3.3 V reverse standoff voltage and 7 A peak pulse current (8/20 µs), it operates across −55 °C to +150 °C ambient and supports system-level protection without compromising impedance matching-critical for GMSL and FPD-Link SerDes links where timing skew and insertion loss must remain tightly controlled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV IEC 61000-4-2 contact discharge; meets ISO 10605 (330 Ω/150 pF); enables robust system-level compliance without external shielding. |
| Channel Capacitance | 0.5 pF typical at 1 MHz, 0 V bias; preserves signal integrity on 10 Gbps USB 3.2 and HDMI 2.0 differential channels. |
| Clamping Voltage | 3.5 V (positive), −3.5 V (negative) at 5 A TLP; limits transient overvoltage to safe levels for sensitive SerDes receivers. |
| Dynamic Resistance | 0.4 Ω typical at 10 A, 100 ns TLP pulse; enables fast energy shunting with minimal voltage overshoot during ESD events. |
| Reverse Standoff | 3.3 V maximum VRWM; compatible with 3.3 V I/O rails of USB 3.2 PHYs, HDMI TMDS buffers, and GMSL deserializers. |
| Package | DFN2510D-10 (SOT1176D), 2.5 × 1.0 × 0.75 mm, 0.5 mm pitch, side-wettable flanks; supports automated optical inspection and high-density layout. |
| AEC-Q101 | Qualified per AEC-Q101-004 Rev D; validated for automotive infotainment, camera links, and display modules requiring extended temperature reliability. |
Pinout & Package
DFN2510D-10 (SOT1176D) is a leadless, surface-mount plastic package measuring 2.5 mm × 1.0 mm × 0.75 mm with 10 terminals, 0.5 mm pitch, and side-wettable flanks for solder-joint inspection. The package supports high thermal dissipation and mechanical stability in automotive and industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection input for first high-speed differential pair (e.g., USB 3.2 TX+/−, HDMI TMDS0+) |
| 2 | CH2 | ESD protection input for second differential pair (e.g., USB 3.2 RX+/−, HDMI TMDS1+) |
| 3 | GND | Dedicated ground return path for CH1/CH2 clamping; minimizes loop inductance and improves ESD response speed |
| 4 | CH3 | ESD protection input for third differential pair (e.g., HDMI TMDS2+, DisplayPort Lane 0+) |
| 5 | CH4 | ESD protection input for fourth differential pair (e.g., HDMI Clock+, GMSL SerDes data lane) |
| 6–10 | n.c. | No internal connection; electrically isolated terminals; used for mechanical anchoring and thermal conduction |
Key Features
| Feature | Design Value |
|---|---|
| Pass-through signal routing | Linear, symmetric pin layout (CH1–CH4 interleaved with GND) enables direct in-line placement on differential traces without stubs or vias. |
| Matched 0.5 mm trace spacing | Terminal pitch matches standard high-speed PCB trace spacing, eliminating need for fan-out layers and reducing crosstalk risk. |
| Deep snap-back clamping | Sub-1 V clamping window below breakdown voltage ensures rapid transition into low-impedance state during ESD, limiting bus voltage excursion. |
| Side-wettable flanks (SWF) | Exposed copper sidewalls enable automated optical inspection of solder fillets-critical for zero-defect automotive assembly lines. |
| Low leakage current | ≤100 nA per channel at 3.3 V reverse bias; prevents DC loading of high-impedance receiver inputs in USB and HDMI PHYs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.6 pF capacitance, ±12 kV IEC 61000-4-2, 3.6 V VRWM, no AEC-Q101 qualification | Targeted at consumer USB 3.0 and DisplayPort; not rated for automotive temperature range or GMSL SerDes reliability | Select when cost sensitivity outweighs AEC-Q101 requirement and 0.1 pF higher capacitance is acceptable for ≤5 Gbps links. |
| SP3205-01HTG | 0.35 pF capacitance, ±15 kV IEC 61000-4-2, 3.3 V VRWM, AEC-Q101 qualified, but only 2-channel configuration | Requires two devices for 4-lane protection; lacks integrated dual-GND layout for optimal high-speed layout symmetry | Prefer for space-constrained designs needing lowest possible capacitance on critical 10 Gbps lanes, accepting higher BOM count and routing complexity. |
Compared with TPD4E05U06DQAR and SP3205-01HTG, PESD4USB3U-TBSAX uniquely combines 4-channel integration, AEC-Q101 qualification, side-wettable flanks, and matched 0.5 mm trace pitch-making it the only single-package solution for automotive-grade 10 Gbps USB 3.2 and HDMI 2.0 protection with AOI-compatible manufacturability.

FAQ
What is the maximum operating temperature for PESD4USB3U-TBSAX?
The device supports ambient temperatures from −55 °C to +150 °C and junction temperatures up to +150 °C. This range satisfies under-hood automotive applications and industrial edge computing environments where thermal cycling and sustained high-temperature operation are required. Storage temperature extends to −65 °C to +150 °C.
Can PESD4USB3U-TBSAX be used for bidirectional high-speed signals like USB 3.2 differential pairs?
Yes-though unidirectional in construction, its symmetrical clamping behavior (3.5 V positive / −3.5 V negative) and low 0.5 pF capacitance make it fully compatible with AC-coupled differential signaling. It is explicitly validated for SuperSpeed USB 3.2 at 10 Gbps in both transmit and receive directions per Nexperia's application notes and USB-IF test reports.
Does the 'n.c.' marking on pins 6–10 indicate they must be left floating on the PCB?
No-pins 6–10 are internally unconnected but externally exposed for mechanical anchoring and thermal conduction. Nexperia recommends soldering them to a thermal pad or ground plane to improve heat dissipation and mechanical reliability, especially in automotive vibration environments. They must not be electrically tied to active nets.
How does the snap-back clamping mechanism differ from standard TVS diodes in ESD response?
Unlike conventional avalanche-based TVS diodes, PESD4USB3U-TBSAX uses an advanced silicon-controlled rectifier (SCR)-like snap-back structure that triggers at ~6 V and rapidly drops to ~0.4 Ω dynamic resistance. This reduces clamping voltage to ±3.5 V at 5 A-over 40% lower than typical TVS devices-minimizing stress on downstream SerDes receivers during ESD events.
