Product details
Overview
PESD4USB3BTBS-QJ from Nexperia is a bidirectional 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, 0.3 pF channel capacitance, and 0.5 Ω dynamic resistance in a DFN2510D-10 (SOT1176D) package with side-wettable flanks-enabling AOI and automotive-grade reliability.
For engineers reviewing the PESD4USB3BTBS-QJ datasheet, PESD4USB3BTBS-QJ pinout, PESD4USB3BTBS-QJ application, or PESD4USB3BTBS-QJ equivalent, key selection criteria include low-capacitance signal integrity preservation, AEC-Q101 qualification for automotive infotainment, matched trace spacing for impedance control, snap-back clamping behavior, and compatibility with 10 Gbps differential data lanes.
Technical Context
This device implements a bidirectional snap-back clamping structure optimized for transient suppression on high-speed differential pairs. Its ultra-low 0.3 pF capacitance per channel minimizes signal distortion at 10 Gbps, while the 0.5 Ω dynamic resistance ensures clamping voltage remains below ±5.5 V under ±5 A TLP stress.
The DFN2510D-10 package integrates four independent ESD channels (CH1–CH4), two ground terminals (Pins 3 & 8), and four no-connect terminals (Pins 6, 7, 9, 10), enabling pass-through routing without stubs or vias-critical for maintaining 90 Ω differential impedance in USB 3.2 and GMSL layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV per IEC 61000-4-2 Level 4 (contact); meets ISO 10605 with 330 Ω/150 pF network-ensures system-level robustness against human-body-model discharges. |
| Channel Capacitance | 0.24–0.3 pF @ 1 MHz, 0 V bias-preserves signal integrity on 10 Gbps USB 3.2 and HDMI 2.0 differential lines without measurable eye closure. |
| Clamping Voltage | ±5.5 V @ ±5 A TLP pulse-limits transient overvoltage to safe levels for downstream PHY receivers in GMSL and FPD-Link SerDes. |
| Dynamic Resistance | 0.5 Ω @ 10 A, 100 ns TLP-enables rapid voltage collapse during ESD events, reducing energy dissipation in protected ICs. |
| Reverse Standoff | 3.3 V maximum-compatible with 3.3 V I/O rails of USB 3.2 transceivers and DisplayPort source devices without leakage-induced signal degradation. |
| Breakdown Voltage | 6–9 V @ 1 mA-provides sufficient margin above 3.3 V operating voltage while triggering reliably before damage to sensitive interface circuitry. |
| AEC-Q101 Qualified | Qualified per Automotive Electronics Council stress test standard-validates suitability for under-hood and infotainment applications requiring extended temperature operation (−55 °C to +150 °C). |
Pinout & Package
DFN2510D-10 (SOT1176D) is a leadless, 10-terminal 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. Its compact footprint supports dense PCB layouts in automotive display modules and USB-C docking stations.
| 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 return path; must be connected to low-impedance chassis or digital ground plane |
| 4 | CH3 | ESD protection input/output for third differential pair (e.g., HDMI TMDS0+/− or GMSL DATA+/−) |
| 5 | CH4 | ESD protection input/output for fourth differential pair (e.g., HDMI TMDS1+/− or GMSL CLK+/−) |
| 6 | n.c. | No internal connection; left floating or tied to ground only if required by PCB mechanical constraints |
| 7 | n.c. | No internal connection; electrically isolated-no routing or thermal tie recommended |
| 8 | GND | Secondary ground terminal; improves current distribution symmetry and reduces ground loop inductance for multi-channel protection |
| 9 | n.c. | No internal connection; unused pad-must not be soldered or routed to avoid parasitic coupling |
| 10 | n.c. | No internal connection; reserved for package mechanical stability-no electrical function |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional snap-back clamping | Enables symmetric ±15 kV ESD protection without polarity-sensitive layout-reduces design risk for AC-coupled differential signals. |
| 0.3 pF channel capacitance | Minimizes insertion loss and phase skew on 10 Gbps links, supporting full compliance with USB 3.2 Gen 2 and HDMI 2.0 eye diagram masks. |
| Side-wettable flanks (SWF) | Allows 100% automated optical inspection of solder joint quality-critical for zero-defect automotive manufacturing requirements. |
| Matched 0.5 mm trace spacing | Aligns precisely with standard 90 Ω differential microstrip routing rules, eliminating need for compensation gaps or neck-downs. |
| Pass-through signal routing | Supports direct in-line placement between connector and PHY without stubs, vias, or bends-maintaining signal integrity across all four channels. |

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 capacitance, ±12 kV IEC 61000-4-2, 6-pin SON package-higher capacitance and lower ESD rating than PESD4USB3BTBS-QJ. | Targeted at USB 2.0 and 3.0 (5 Gbps), not validated for 10 Gbps USB 3.2 Gen 2 or GMSL. | Select when cost sensitivity outweighs 10 Gbps performance needs and AEC-Q101 is not required. |
| SP3222-04UTG | 0.35 pF capacitance, ±15 kV ESD, SOT-23-6 package-single-channel, requires four discrete devices versus one quad-channel solution. | Suitable for space-tolerant industrial designs but increases PCB area and assembly cost vs. integrated quad-channel DFN2510D-10. | Choose only if legacy SOT-23 footprint reuse is mandatory and layout density is not constrained. |
Compared with TPD4E05U06DQAR and SP3222-04UTG, PESD4USB3BTBS-QJ offers superior 10 Gbps signal integrity via lower capacitance, higher ESD robustness, AEC-Q101 qualification, and 4-channel integration-reducing BOM count, PCB area, and assembly complexity in automotive and high-density docking applications.

FAQ
What is the maximum data rate supported by PESD4USB3BTBS-QJ?
PESD4USB3BTBS-QJ is explicitly characterized and qualified for SuperSpeed USB 3.2 Gen 2 operation at 10 Gbps, with verified 0.3 pF channel capacitance and minimal insertion loss up to 5 GHz-ensuring full compliance with USB-IF eye diagram and jitter specifications.
Does PESD4USB3BTBS-QJ require external bias or control signals?
No. PESD4USB3BTBS-QJ is a passive, bidirectional ESD protection device with no power pins, enable inputs, or configuration registers. It operates solely through intrinsic silicon clamping behavior and requires no external components or firmware support.
How does the snap-back clamping mechanism improve system protection?
The snap-back structure reduces clamping voltage from typical breakdown levels (~6–9 V) to ±5.5 V under 5 A TLP stress, limiting transient energy delivered to downstream ICs. This deep clamping prevents latch-up and oxide damage in sensitive USB 3.2 and GMSL PHYs during ESD events.
Can PESD4USB3BTBS-QJ be used in non-automotive applications?
Yes. While AEC-Q101 qualified, PESD4USB3BTBS-QJ is equally effective in industrial, medical, and premium consumer applications requiring robust ESD protection for 10 Gbps interfaces-its performance parameters and DFN2510D-10 package are technology-agnostic and widely adopted outside automotive.
