Product details
Overview
PESD4USB5B-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 discharge protection, 0.3 pF channel capacitance, 0.5 Ω dynamic resistance, 5 V reverse standoff voltage, and AEC-Q101 qualification for automotive infotainment and camera links.
For engineers reviewing the PESD4USB5B-TBSAX datasheet, PESD4USB5B-TBSAX pinout, PESD4USB5B-TBSAX application, or PESD4USB5B-TBSAX equivalent, key selection criteria include ultra-low capacitance for signal integrity, snap-back clamping behavior for low-voltage rail protection, side-wettable flanks for AOI compatibility, and matched trace spacing for high-speed PCB layout.
Technical Context
This device implements a deep snap-back clamping structure with negative dynamic resistance to reduce clamping voltage during ESD transients-achieving ±5.5 V clamping at ±5 A per channel under IEC 61000-4-5 conditions. Its bidirectional architecture protects both polarities without external biasing.
Designed for differential high-speed data lanes, it maintains impedance continuity via pass-through routing and supports 0.5 mm trace pitch. The DFN2510D-10 package enables automated optical inspection and thermal performance up to 150 °C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U2U-2/TR | Single-channel, 0.25 pF capacitance, ±12 kV IEC 61000-4-2, SOT-23-3 package | Limited to two-lane protection; requires four devices for same coverage; no SWF or AEC-Q101 rating | Select when cost-per-channel is prioritized over integration and automotive qualification |
| TPD4E05U06DQAR | Four-channel, 0.5 pF capacitance, ±12 kV IEC 61000-4-2, X2SON-10 package, no SWF | Higher capacitance degrades 10 Gbps USB3 eye diagram margin; lacks side-wettable flanks for AOI | Prefer for non-automotive consumer electronics where AOI is not required and 0.5 pF is acceptable |
Compared with ESD5V3U2U-2/TR and TPD4E05U06DQAR, PESD4USB5B-TBSAX uniquely combines AEC-Q101 qualification, side-wettable flanks, 0.3 pF capacitance, and ±15 kV protection in a single 10-terminal DFN-enabling robust, inspectable, and space-efficient protection for next-gen automotive high-speed buses.

FAQ
What is the maximum recommended trace length between PESD4USB5B-TBSAX and the protected connector?
Per Nexperia application guidance, the distance from the device to the connector should be ≤3 mm for optimal ESD performance. Longer traces increase inductance, raising clamping voltage during fast transients and risking downstream IC damage. Ground vias must be placed within 1 mm of each GND pin to minimize loop inductance.
Does PESD4USB5B-TBSAX require external biasing or series resistors?
No. PESD4USB5B-TBSAX operates bidirectionally without external bias and is designed for direct placement in series with high-speed differential lines. Adding series resistors would degrade signal integrity and is not recommended. Its snap-back behavior self-triggers only during ESD events, drawing negligible leakage (<100 nA) during normal operation.
Can PESD4USB5B-TBSAX protect against electrical fast transients (EFT) per IEC 61000-4-4?
While qualified to IEC 61000-4-2 (ESD) and ISO 10605, PESD4USB5B-TBSAX is not characterized for IEC 61000-4-4 EFT immunity. Its 7 A peak pulse current rating applies to 8/20 µs surges (IEC 61000-4-5), not repetitive EFT bursts. For EFT-hardened designs, supplemental filtering or dedicated EFT suppressors are required.
How does the 'n.c.' pin configuration affect PCB layout and thermal performance?
Pins 6–10 are unconnected but serve critical mechanical and thermal roles: they provide structural rigidity and enhance heat dissipation into the PCB copper pour. Layout must maintain full solder mask opening and thermal relief-free copper connection to inner ground planes-omitting them reduces thermal resistance by up to 12 °C/W and improves long-term reliability under sustained ESD stress.
