Product details
Overview
PESD4USB3B-TBRX from Nexperia is a unidirectional, 4-channel ESD protection diode array designed for high-speed USB 3.0/3.1 SuperSpeed differential data lines. It provides ±15 kV IEC 61000-4-2 contact discharge and ±20 kV air discharge protection, with ultra-low dynamic resistance (0.3 Ω typical) and low clamping voltage (8.5 V at 8 A), enabling robust signal integrity in compact portable electronics.
For engineers reviewing the PESD4USB3B-TBRX datasheet, PESD4USB3B-TBRX pinout, PESD4USB3B-TBRX application, or PESD4USB3B-TBRX equivalent, this device is selected for USB 3.x interface protection where sub-0.5 pF channel capacitance, <1 ns response time, and AEC-Q101 qualification for automotive infotainment are critical design requirements.
Technical Context
This device integrates four matched, low-capacitance ESD protection diodes in a single DFN1713-6 (SOT1118) package, each channel configured as a cathode-to-rail clamp to ground. Its architecture uses planar silicon technology optimized for minimal parasitic capacitance and fast transient response without compromising leakage current (<10 nA at 5 V).
The layout supports differential pair routing with symmetrical trace lengths and impedance matching - essential for maintaining USB 3.0's 90 Ω differential impedance and 5 Gbps data rate. The device operates over -40 °C to +125 °C and meets ISO 10605 for automotive electrostatic discharge immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±15 kV contact, ±20 kV air - ensures full compliance with industrial and automotive ESD immunity standards. |
| Channel Capacitance | 0.4 pF max at 1 MHz - preserves USB 3.0 signal integrity by minimizing insertion loss and jitter. |
| Clamping Voltage (IPP = 8 A) | 8.5 V max - limits transient overvoltage below IC I/O absolute maximum rating (typically 10–12 V). |
| Leakage Current (VR = 5 V) | 10 nA max - prevents DC loading of high-impedance USB receiver inputs. |
| Dynamic Resistance | 0.3 Ω typical - reduces voltage overshoot during fast transients, improving protection margin. |
| Operating Temperature | −40 °C to +125 °C - supports deployment in automotive cabin and under-hood modules. |
Pinout & Package
Supplied in a 1.7 mm × 1.3 mm × 0.5 mm DFN1713-6 (SOT1118) leadless package with exposed thermal pad for enhanced power dissipation and board-level EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Anode (D1+) | Input for first USB 3.0 differential pair positive line (TX+/RX+). |
| 2 | Channel 1 Cathode (GND) | Common ground connection for all four channels; tied to PCB ground plane via thermal pad. |
| 3 | Channel 2 Anode (D1−) | Input for first USB 3.0 differential pair negative line (TX−/RX−). |
| 4 | Channel 3 Anode (D2+) | Input for second USB 3.0 differential pair positive line (optional dual-lane support). |
| 5 | Channel 3 Cathode (GND) | Redundant ground terminal for improved current sharing and lower inductance path. |

| AEC-Q101 qualified | Qualified for automotive applications including head units and USB-C docking modules. |
| Symmetric differential layout | Matched anode-cathode paths minimize skew between TX+/TX−, preserving common-mode rejection. |
| Low clamping voltage with high peak pulse current | 8.5 V clamping at 8 A - protects downstream USB 3.0 PHYs without triggering overvoltage shutdown. |
| DFN1713-6 footprint | 1.7 × 1.3 mm area - saves >60% board space vs. discrete diode solutions for quad-channel protection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4EUSB30DRBR | 0.5 pF typical capacitance; ±12 kV IEC 61000-4-2; no AEC-Q101 qualification. | Targeted at commercial-grade USB 3.0 peripherals only; not suitable for automotive environments. | Select when cost sensitivity outweighs automotive qualification and 0.1 pF capacitance margin is acceptable. |
| SP3205-04UTG | 0.35 pF typical capacitance; ±15 kV IEC 61000-4-2; SOD-323 package (larger footprint, higher inductance). | Supports same USB 3.0 speed but lacks thermal pad and automotive temp range (−40 °C to +85 °C only). | Choose if legacy SMT process cannot accommodate DFN1713-6 reflow profile or thermal pad stencil design. |
Compared with TPD4EUSB30DRBR and SP3205-04UTG, PESD4USB3B-TBRX uniquely combines AEC-Q101 qualification, 0.4 pF capacitance, and DFN1713-6 thermal performance - making it the only option qualified for automotive USB 3.0 interfaces requiring simultaneous high-speed signal fidelity and extended temperature reliability.

FAQ
What is the maximum peak pulse current rating for PESD4USB3B-TBRX?
The device is rated for 8 A peak pulse current per channel under IEC 61000-4-5 8/20 µs waveform conditions. This value is validated through standardized surge testing and reflects the maximum transient energy the diode can safely divert without degradation, assuming proper PCB thermal design and grounding.
Does PESD4USB3B-TBRX require external bias or control signals?
No - it operates passively as a clamping diode array with no external power, enable pins, or configuration logic. Its protection function activates automatically when transient voltage exceeds the forward conduction threshold (~5.5 V), making it compatible with all USB 3.0 PHY implementations without firmware or hardware modification.
Can PESD4USB3B-TBRX be used for USB 3.2 Gen 2 (10 Gbps) applications?
Yes - its 0.4 pF channel capacitance and <1 ns response time maintain signal integrity up to 5 GHz, covering the fundamental frequency and first harmonic of 10 Gbps NRZ signaling. Layout adherence to controlled impedance (90 Ω differential) and minimized stub length remains critical for Gen 2 compliance.
Is the thermal pad on the DFN1713-6 package electrically isolated?
No - the exposed thermal pad is internally connected to Pin 2 (cathode/GND) and must be soldered to a solid PCB ground plane. This connection provides both thermal dissipation and low-inductance return path for ESD current, and omission will degrade clamping performance and thermal reliability.
