Product details
Overview
PESD4USB3B-TBSAX 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, 0.5 Ω dynamic resistance, 3.3 V reverse standoff voltage, and AEC-Q101 qualification for automotive infotainment and camera links.
For engineers reviewing the PESD4USB3B-TBSAX datasheet, PESD4USB3B-TBSAX pinout, PESD4USB3B-TBSAX application, or PESD4USB3B-TBSAX equivalent, this page provides verified package mapping (DFN2510D-10/SOT1176D), terminal roles, real-world clamping behavior under 5 A transients, and validated alternatives for USB 3.2 and GMSL signal line protection.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance to achieve deep voltage clamping during ESD events-reducing VCL to ±5.5 V at ±5 A while maintaining sub-0.3 pF capacitance per channel. Its design targets impedance-critical differential pairs where signal integrity must be preserved up to 10 Gbps.
The DFN2510D-10 package features side-wettable flanks for AOI-compatible reflow, matched 0.5 mm trace spacing, and dual GND pins (pins 3 and 8) to minimize ground inductance and improve transient return path integrity across four independent bidirectional channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DPYR (Texas Instruments) | 0.5 pF typical capacitance; ±12 kV IEC 61000-4-2; 3.6 V VRWM; no AEC-Q101 rating | Targeted at consumer USB 2.0/HDMI; not qualified for automotive temperature or vibration stress | Select when cost sensitivity outweighs automotive qualification and ultra-low capacitance is secondary |
| SZESD7371MUTAG (onsemi) | 0.35 pF max capacitance; ±15 kV IEC 61000-4-2; 3.3 V VRWM; AEC-Q101 qualified; 4-channel DFN1610-8 | Smaller 1.6 mm × 1.0 mm footprint but only 8 terminals-requires redesign of GND and n.c. layout | Select when board space is constrained and dual-GND layout flexibility is less critical than miniaturization |
Compared with TPD4E001DPYR and SZESD7371MUTAG, PESD4USB3B-TBSAX uniquely combines 0.3 pF capacitance, dual-GND terminals for low-inductance return paths, side-wettable flanks for AOI, and AEC-Q101 qualification-making it optimal for production automotive USB 3.2 and GMSL designs requiring zero rework risk.

FAQ
What is the maximum operating temperature for PESD4USB3B-TBSAX?
The device supports ambient temperatures from −55 °C to +150 °C and junction temperatures up to +150 °C. This range satisfies AEC-Q101 requirements for under-hood and exterior automotive applications, including camera modules exposed to direct sunlight or engine heat.
Can PESD4USB3B-TBSAX be used on single-ended signals like USB 2.0 D+ and D−?
Yes-it is explicitly rated for USB 2.0 protection in addition to SuperSpeed USB 3.2. Each channel operates bidirectionally with 3.3 V VRWM and 0.3 pF capacitance, making it suitable for both single-ended D+/D− and differential TX/RX pairs without derating or layout changes.
Why does PESD4USB3B-TBSAX have two GND pins (pins 3 and 8)?
Dual GND pins reduce ground loop inductance and separate return paths for CH1–CH2 and CH3–CH4 groups. This minimizes crosstalk between protected channels and improves clamping symmetry during multi-pin ESD events-critical for HDMI and GMSL SerDes where timing skew degrades link reliability.
Is the 0.3 pF capacitance specified per channel or total?
The 0.3 pF value is per channel, measured at 1 MHz and 0 V bias. All four channels (CH1–CH4) maintain this capacitance independently, confirmed in Table 5 of the datasheet. This ensures consistent impedance matching and minimal insertion loss across all protected differential pairs.
