Product details
Overview
PESD4USB5B-TTS 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 Level 4 ESD protection, 0.3 pF channel capacitance, and 0.5 Ω dynamic resistance in a DFN2510D-10 (SOT1165D) package with side-wettable flanks-enabling AOI and automotive infotainment signal line protection.
For engineers reviewing the PESD4USB5B-TTS datasheet, PESD4USB5B-TTS pinout, PESD4USB5B-TTS application, or PESD4USB5B-TTS equivalent, this device is selected for ultra-low-capacitance, AEC-Q101-qualified ESD hardening of differential high-speed data lanes where signal integrity and system-level robustness are critical.
Technical Context
The PESD4USB5B-TTS implements a snap-back clamping structure with negative dynamic resistance, enabling deep voltage clamping during ESD transients while maintaining low leakage (<100 nA at 5 V) and stable reverse standoff voltage (5 V). Its bidirectional architecture protects both polarities without polarity constraints on data lines.
Each of its four protected channels operates independently with matched trace spacing (0.5 mm), side-wettable flanks for solder-joint inspection, and pass-through routing compatibility-supporting impedance-controlled PCB layouts for HDMI, USB 3.2, and GMSL links without signal path disruption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV per IEC 61000-4-2 Level 4 (contact/air) and ISO 10605 - exceeds automotive and industrial system-level immunity requirements. |
| Channel Capacitance | 0.24–0.3 pF at 1 MHz, 0 V bias - preserves signal integrity on 10 Gbps USB 3.2 and HDMI 2.0 differential pairs. |
| Dynamic Resistance | 0.5 Ω (TLP, 100 ns pulse) - minimizes clamping voltage overshoot during fast ESD events, reducing stress on downstream ICs. |
| Reverse Standoff Voltage | 5 V - compatible with 3.3 V and 5 V high-speed interface supply rails without DC blocking concerns. |
| Breakdown Voltage | 6–9 V (1 mA test current) - ensures reliable triggering above normal operating voltage while avoiding false conduction. |
| AEC-Q101 Qualified | Qualified per Automotive Electronics Council stress test standard - validated for under-hood and infotainment module deployment. |
Pinout & Package
Package: DFN2510D-10 (SOT1165D), leadless 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.
| 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 | Low-inductance ground return path for ESD current dissipation; must be connected to solid ground plane. |
| 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 terminals - may be left unconnected or tied to ground per layout needs. |
| 8 | GND | Second dedicated ground terminal for enhanced thermal and ESD current distribution across package body. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance (0.3 pF) | Enables use on 10 Gbps SuperSpeed USB 3.2 and HDMI 2.0 links without measurable insertion loss or eye diagram degradation. |
| Deep snap-back clamping | Reduces clamping voltage to ±5.5 V at ±5 A transient, limiting stress on sensitive SerDes receiver inputs. |
| Side-wettable flanks (SWF) | Supports automated optical inspection of solder joints on bottom-terminated DFN packages - critical for automotive production traceability. |
| Matched 0.5 mm trace spacing | Aligns with standard high-speed PCB routing rules, simplifying layout and minimizing differential skew between protected lanes. |
| AEC-Q101 qualification | Validates reliability under temperature cycling, humidity, and mechanical shock - required for automotive display and camera modules. |
Applications
| Infotainment USB/HDMI Interface | Automotive Display Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPD4E05U06DQAR | 0.5 pF typical capacitance; ±12 kV IEC 61000-4-2; same DFN package but no AEC-Q101 qualification. | Limited to industrial/commercial USB 3.0 and DisplayPort; not approved for automotive front-end modules. | Select when AEC-Q101 is not required and higher capacitance is acceptable for ≤5 Gbps links. |
| ON Semi SZ1.5SMC15AT3G | Unidirectional, 15 V standoff, 150 pF capacitance - unsuitable for high-speed data lines. | Only appropriate for low-frequency power rail or GPIO protection; incompatible with USB/HDMI/GMSL. | Avoid for any high-speed interface; use only for DC supply or low-speed signal line hardening. |
Compared with TPD4E05U06DQAR, PESD4USB5B-TTS offers lower capacitance and automotive qualification; compared with SZ1.5SMC15AT3G, it enables signal-rate-transparent ESD protection rather than sacrificing bandwidth for voltage rating.

FAQ
What is the maximum data rate supported by PESD4USB5B-TTS?
The device is explicitly characterized and qualified for SuperSpeed USB 3.2 Gen 2 (10 Gbps), HDMI 2.0 (18 Gbps aggregate), and GMSL links up to 3.125 Gbps per lane. Its 0.3 pF capacitance and matched layout enable minimal signal distortion at these rates, confirmed by Nexperia's application testing and TLP characterization.
Can PESD4USB5B-TTS be used on single-ended signals like UART or I²C?
Yes, but not optimal: its ultra-low capacitance and snap-back behavior are over-engineered for low-speed buses. For UART/I²C, lower-cost, higher-capacitance ESD diodes (e.g., PESD1CAN) provide adequate protection with simpler layout and cost. PESD4USB5B-TTS adds unnecessary complexity and footprint overhead in such cases.
Why does Pin 6–7 and Pin 9–10 show 'n.c.' in the pinout?
These terminals have no internal die connection and serve only as mechanical anchors or thermal relief pads. They may be left floating, grounded, or used for fiducial alignment-Nexperia confirms no electrical function. Their presence supports package manufacturability and thermal stability without affecting ESD performance.
Is the 0.5 Ω dynamic resistance measured per channel or total?
It is measured per channel under Transmission Line Pulse (TLP) conditions (100 ns pulse, 10 A), as specified in Table 6 of the datasheet. Each CH1–CH4 channel exhibits independent 0.5 Ω dynamic resistance during clamping, ensuring consistent protection across all four protected lanes without cross-talk or shared impedance effects.
