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, 0.24–0.3 pF per channel capacitance, 0.5 Ω dynamic resistance, and 5 V reverse standoff voltage in a DFN2510D-10 (SOT1165D) package with side-wettable flanks.
For engineers reviewing the PESD4USB5B-TTS datasheet, PESD4USB5B-TTS pinout, PESD4USB5B-TTS application, or PESD4USB5B-TTS equivalent, this device supports impedance-critical routing in automotive infotainment, A/V monitors, and high-bandwidth SerDes links where low-capacitance, snap-back clamping, and AOI-compatible packaging are essential.
Technical Context
This device implements a deep 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 line capacitance. Its architecture avoids latch-up under transient stress and sustains operation up to 150 °C junction temperature.
Qualified to AEC-Q101, it supports automotive-grade reliability across four protected channels (CH1–CH4), dual GND terminals (pins 3 and 8), and two isolated no-connect pins (6, 7, 9, 10). The DFN2510D-10 package features 0.5 mm pitch, 2.5 mm × 1.0 mm footprint, and side-wettable flanks for automated optical inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV contact/air discharge (IEC 61000-4-2 Level 4); ±15 kV ISO 10605 (330 Ω/150 pF) |
| Reverse Standoff Voltage | 5 V - ensures signal integrity on 3.3 V and 5 V high-speed buses without leakage or conduction |
| Diode Capacitance | 0.24–0.3 pF per channel at 1 MHz - preserves signal rise/fall times and minimizes insertion loss on 10 Gbps links |
| Dynamic Resistance | 0.5 Ω - enables rapid clamping response and low residual voltage during ESD events |
| Clamping Voltage | ±5.5 V at ±5 A (TLP, 100 ns) - limits downstream IC stress below safe thresholds for USB 3.2/HDMI receivers |
| Breakdown Voltage | 6–9 V (1 mA test current) - provides margin above 5 V operating rails while triggering reliably during ESD |
| Ambient Temp Range | −55 °C to +150 °C - supports under-hood and display module deployment in automotive environments |
Pinout & Package
DFN2510D-10 (SOT1165D) is a 10-terminal, leadless, thin small-outline package measuring 2.5 mm × 1.0 mm × 0.75 mm with 0.5 mm pitch and side-wettable flanks for AOI compatibility.

Key Features
| Feature | Design Value |
|---|---|
| Pass-through signal routing | Enables direct trace routing through CH1–CH4 pins without vias or stubs - critical for maintaining 50 Ω differential impedance on USB 3.2/HDMI lanes |
| Side-wettable flanks (SWF) | Facilitates automated optical inspection of solder joints on bottom-terminated DFN packages - eliminates X-ray dependency in automotive manufacturing |
| AEC-Q101 qualification | Validated for automotive use per stress-test requirements including HTGB, HTRB, and ESD - supports ASIL-B system integration without additional qualification effort |
| Matched 0.5 mm trace spacing | Aligns with standard PCB fabrication tolerances for high-density routing - reduces risk of crosstalk and impedance discontinuity in multi-lane layouts |
| Deep snap-back clamping | Reduces clamping voltage by >40% versus conventional TVS diodes - protects sensitive SerDes PHYs against damage during repeated ESD strikes |
Applications
| Automotive Infotainment Hub | HDMI 2.0 Display Interface |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E004DRYR | 0.5 pF typical capacitance; ±12 kV IEC 61000-4-2; 3.6 V VRWM; SOT-563 package | Lower ESD rating and higher capacitance limit use to USB 2.0 or lower-speed HDMI; lacks AEC-Q101 qualification | Select when cost sensitivity outweighs automotive qualification and 10 Gbps support |
| SP3205-01UTG | 0.35 pF typical capacitance; ±15 kV IEC 61000-4-2; 5 V VRWM; SOT-23-6 package with only 2 channels | Requires two devices for 4-channel protection; larger footprint and no side-wettable flanks hinder AOI in automotive SMT lines | Select only if DFN2510D-10 assembly capability is unavailable and dual-GND thermal management is not required |
Compared with TPD4E004DRYR and SP3205-01UTG, PESD4USB5B-TTS uniquely combines AEC-Q101 qualification, 4-channel integration in AOI-friendly DFN2510D-10, and sub-0.3 pF capacitance - making it the only option qualified for single-package 10 Gbps USB 3.2 and HDMI 2.0 protection in automotive production.

FAQ
What is the maximum peak pulse current the PESD4USB5B-TTS can handle?
The device supports a rated peak pulse current of 7 A per channel under 8/20 µs waveform conditions (IEC 61000-4-5). This rating ensures robust handling of surge events beyond standard ESD pulses, such as those induced by nearby lightning or power rail coupling, while maintaining clamping performance within ±5.5 V.
Can PESD4USB5B-TTS be used on USB 2.0 interfaces?
Yes - its 5 V reverse standoff voltage, ±15 kV ESD rating, and 0.24–0.3 pF capacitance make it fully compatible with USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) signaling. The low capacitance prevents signal degradation, and the snap-back clamping ensures reliable protection even during repeated hot-plug events.
Why does the device have four no-connect pins?
Pins 6, 7, 9, and 10 are internally unconnected and serve mechanical and layout purposes: they maintain symmetrical package geometry for thermal balance and solder joint reliability, enable consistent stencil aperture design, and allow grounding flexibility (e.g., tying n.c. pins to GND plane for improved shielding) without affecting electrical function.
Is the PESD4USB5B-TTS compatible with lead-free reflow profiles?
Yes - the DFN2510D-10 package is qualified for standard lead-free reflow profiles up to 260 °C peak temperature. Recommended stencil thickness is 0.1 mm, and the side-wettable flanks ensure reliable solder fillet formation and AOI detectability, meeting IPC-J-STD-020 and J-STD-002 requirements for automotive production.
