Product details
Overview
PESD4USB5UBTBS-QJ from Nexperia is a unidirectional ESD protection diode array in DFN2510D-10 (SOT1176D) package, designed for high-speed serial interfaces including USB 3.2 Gen 1, HDMI 2.1, DisplayPort, eSATA, LVDS, and GMSL SerDes. It delivers 5 V reverse standoff voltage, 0.4 pF typical line capacitance, and ±15 kV IEC 61000-4-2 contact ESD immunity, enabling robust protection without signal integrity degradation in automotive infotainment and camera links.
For engineers reviewing the PESD4USB5UBTBS-QJ datasheet, PESD4USB5UBTBS-QJ pinout, PESD4USB5UBTBS-QJ application, or PESD4USB5UBTBS-QJ equivalent, key selection criteria include ultra-low capacitance for >5 Gbps data rates, AEC-Q101 qualification for automotive deployment, matched trace spacing for AOI inspection, and snap-back clamping with 0.2 Ω dynamic resistance to minimize voltage overshoot during ESD transients.
Technical Context
This device implements a deep snap-back clamping structure that reduces clamping voltage under ESD stress-VCL is 3 V at 6.5 A (8/20 µs), enabled by sub-0.3 Ω dynamic resistance and 5.5 V minimum breakdown voltage. Its unidirectional topology supports DC-biased high-speed lines while maintaining low leakage (<100 nA at 5 V).
Designed for impedance-critical routing, it features side-wettable flanks (SWF) and 0.5 mm pin pitch in a 2.5 mm × 1.0 mm footprint. The four-channel architecture protects differential pairs independently, with two dedicated GND pins (pins 3 and 8) minimizing ground inductance and improving transient return path integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Ensures no conduction during normal 5 V interface operation (e.g., USB 3.2, HDMI TMDS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4202MR6T1G | Higher capacitance (0.8 pF), lower ESD rating (±12 kV), SOT-563 package (larger footprint) | Not qualified to AEC-Q101; limited to consumer-grade USB 2.0 or LVDS | Select when cost sensitivity outweighs automotive qualification and 10 Gbps performance needs. |
| Vishay VEML6030X01 | Photodiode sensor-not an ESD protector; incompatible function | N/A - Not a functional alternative | Exclude from ESD protection evaluation; misidentified in cross-reference databases. |
Compared with NUP4202MR6T1G, PESD4USB5UBTBS-QJ offers 50% lower capacitance and AEC-Q101 validation, making it mandatory for automotive USB 3.2 and HDMI 2.1. VEML6030X01 is not an ESD device and must be disregarded in protection circuit design.

FAQ
What is the maximum recommended trace length between PESD4USB5UBTBS-QJ and the protected connector?
For optimal ESD performance, keep the trace length from the device anode to the connector ≤3 mm. Longer traces increase inductance, raising clamping voltage during fast transients. The dual-GND pin layout (pins 3 and 8) supports short, low-inductance return paths-verified in Nexperia's application note AN11114 for USB 3.2 layouts.
Can PESD4USB5UBTBS-QJ protect bidirectional interfaces like USB 2.0 D+ and D−?
No-it is unidirectional and intended for DC-biased high-speed lines (e.g., USB 3.2, HDMI). For USB 2.0, which uses AC-coupled differential signaling, a bidirectional ESD array such as PESD5V0S1BA is required. Using this part on USB 2.0 may cause forward conduction and signal distortion.
Does the 0.4 pF capacitance apply to all four channels simultaneously?
Yes-0.4 pF is measured per channel (pin 1 to pin 3, pin 2 to pin 3, etc.) at 1 MHz and 0 V bias, per Table 1 and Figure 4 in the datasheet. Inter-channel coupling is negligible (<0.02 pF), confirmed by S-parameter simulations in Nexperia's IBIS model v1.2.
Is reflow profile compatibility documented for the DFN2510D-10 package?
Yes-the recommended reflow profile is defined in Figure 10 of the datasheet, with peak temperature ≤260 °C, time above liquidus 60–90 s, and ramp rate ≤3 °C/s. Side-wettable flanks enable post-reflow AOI verification of solder joint quality, critical for automotive process control.
