Product details
Overview
PESD4USB3BTTS-Q 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 provides ±15 kV IEC 61000-4-2 contact discharge protection, 0.3 pF channel capacitance, 0.5 Ω dynamic resistance, and AEC-Q101 qualification for automotive infotainment and camera links.
For engineers reviewing the PESD4USB3BTTS-Q datasheet, PESD4USB3BTTS-Q pinout, PESD4USB3BTTS-Q application, or PESD4USB3BTTS-Q equivalent, key selection criteria include low-capacitance signal integrity preservation, snap-back clamping behavior for deep voltage suppression, side-wettable flanks for AOI compatibility, and automotive-grade reliability in high-speed differential data paths.
Technical Context
This device implements a bidirectional snap-back clamping structure with negative dynamic resistance, enabling ultra-low clamping voltage (±5.5 V at ±5 A) during ESD transients while maintaining sub-0.3 pF capacitance per channel at 1 MHz and 0 V bias. Its design targets minimal signal distortion on 10 Gbps USB 3.2 and multi-gigabit SerDes links.
The DFN2510D-10 (SOT1165D) package features 0.5 mm pitch, side-wettable flanks for automated optical inspection, and matched 0.5 mm trace spacing to preserve controlled impedance. All four protected channels are isolated from each other and share dual GND terminals for low-inductance return paths.

|---|---|
|
Use Scenario: Protecting USB 3.2 Gen 2 (10 Gbps) upstream/downstream ports in vehicle head units against ESD from hot-plug cables and user contact. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed directly at connector, shunting transient energy to dual GND planes before reaching USB controller PHY. Use Value: Prevents lockup or damage to USB 3.2 transceivers while maintaining <0.3 pF loading to avoid eye diagram closure at 10 Gbps. |
Use Scenario: Shielding HDMI 2.0 TMDS channels in automotive digital dash displays from ESD induced by cable mating/unmating or EMI coupling. IC Role / Device Role / Timing Role: Four-channel ESD suppressor placed adjacent to HDMI receptacle, with matched trace spacing preserving 100 Ω differential impedance. Use Value: Enables full 18 Gbps bandwidth support without signal attenuation or jitter increase due to parasitic capacitance. |
| GMSL SerDes Camera Link | eSATA External Storage Interface |
|
Use Scenario: Securing GMSL serializer outputs in rear-view or surround-view cameras exposed to harsh automotive ESD environments. IC Role / Device Role / Timing Role: Low-capacitance ESD protection on serialized video lanes, leveraging dual GND pins to minimize common-mode noise injection. Use Value: Maintains bit error rate (BER) <1e−12 under ESD stress while supporting >3 Gbps GMSL link rates with minimal timing skew. |
Use Scenario: Safeguarding eSATA ports on ruggedized industrial PCs or automotive DVRs from repeated connector insertion ESD events. IC Role / Device Role / Timing Role: High-energy ESD clamp rated for ±15 kV contact discharge, placed within 3 mm of eSATA connector per IEC 61000-4-2 layout guidelines. Use Value: Sustains 3 Gbps eSATA signaling integrity with <0.3 pF per lane and clamps transients to <±5.5 V before SATA PHY damage threshold. |
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; ±12 kV IEC 61000-4-2; no AEC-Q101 qualification | Targeted at consumer USB/HDMI; lacks automotive temperature range and qualification | Select when cost sensitivity outweighs automotive compliance and ultra-low capacitance requirements |
| SP3205-01UTG | 0.35 pF typical capacitance; ±15 kV IEC 61000-4-2; AEC-Q101 qualified; 5-pin SOT-553 package | Single-channel device requiring four discrete placements; higher board area and routing complexity | Choose only if legacy layout constraints prevent adoption of 10-pin DFN or require different footprint compatibility |
Compared with TPD4E05U06DQAR and SP3205-01UTG, PESD4USB3BTTS-Q delivers lower capacitance (0.3 pF vs. ≥0.35 pF), integrated quad-channel layout, and verified AEC-Q101 performance - making it optimal for space-constrained, high-reliability automotive SerDes and USB 3.2 designs.

FAQ
What is the maximum recommended trace length between PESD4USB3BTTS-Q and the protected connector?
For optimal ESD performance on 10 Gbps interfaces, Nexperia specifies ≤3 mm trace length from device to connector per IEC 61000-4-2 layout guidance. Longer traces increase inductance, raising clamping voltage during fast transients and risking damage to downstream PHYs. The DFN2510D-10's side-wettable flanks support compact placement adjacent to USB/HDMI receptacles.
Does PESD4USB3BTTS-Q require external biasing or control signals?
No. PESD4USB3BTTS-Q is a passive bidirectional ESD suppressor with no power or control pins. It operates solely via avalanche breakdown and snap-back clamping triggered by transient overvoltage. No DC bias, enable lines, or configuration registers are needed - simplifying integration into high-speed data paths.
Can this device protect both AC-coupled and DC-coupled high-speed interfaces?
Yes. With a 3.3 V reverse standoff voltage and bidirectional clamping, PESD4USB3BTTS-Q protects both AC-coupled (e.g., HDMI, DisplayPort) and DC-coupled (e.g., USB 3.2, eSATA) interfaces. Its low leakage (<100 nA at 3.3 V) prevents signal offset in DC-coupled lanes, and its 0.3 pF capacitance avoids resonance issues in AC-coupled paths.
How does the dual-GND configuration improve ESD performance?
Dual GND pins (pins 3 and 8) provide separate low-inductance return paths for CH1–CH2 and CH3–CH4 clamping currents, reducing mutual coupling and ground bounce. This separation maintains clean common-mode rejection during multi-lane ESD events and lowers overall clamping impedance - critical for simultaneous protection of USB 3.2 TX/RX and HDMI TMDS pairs.
