Product details
Overview
PESD4USB5UTBS-QJ from Nexperia is a unidirectional 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, 0.5 pF channel capacitance, and 0.4 Ω dynamic resistance in a DFN2510D-10 (SOT1176D) package with side-wettable flanks-enabling AOI and automotive-grade reliability per AEC-Q101.
For engineers reviewing the PESD4USB5UTBS-QJ datasheet, PESD4USB5UTBS-QJ pinout, PESD4USB5UTBS-QJ application, or PESD4USB5UTBS-QJ equivalent, key selection criteria include low-capacitance signal integrity preservation, snap-back clamping behavior for deep voltage suppression, automotive qualification, and compatibility with 0.5 mm trace spacing PCB layouts for high-speed differential pairs.
Technical Context
This device implements a multi-channel unidirectional snap-back clamping structure optimized for bidirectional high-speed data lines. Each of its four protected channels exhibits 0.4–0.5 pF capacitance at 1 MHz and sub-100 nA reverse leakage at 5 V, ensuring minimal signal distortion on 10 Gbps USB 3.2 and HDMI 2.0 links.
The clamping mechanism achieves 3.5 V positive/negative VCL at ±5 A (TLP), enabled by a negative dynamic resistance characteristic that reduces voltage overshoot during ESD transients. Its DFN2510D-10 package supports automated optical inspection via side-wettable flanks and maintains matched 0.5 mm trace pitch for controlled impedance routing.

Use Value: Matched 0.5 mm pin spacing enables direct routing of 100 Ω differential traces; 3.5 V clamping avoids receiver input damage. |
| GMSL SerDes Camera Link | eSATA External Storage Interface |
|
Use Scenario: Securing GMSL2 serializer outputs in ADAS camera modules exposed to harsh ESD environments during assembly and service. IC Role / Device Role / Timing Role: Front-end ESD guard for bidirectional GMSL data lanes operating up to 6 Gbps, placed immediately after connector. Use Value: Sub-0.5 pF capacitance preserves signal rise/fall times; AEC-Q101 qualification ensures operation across −40 °C to +105 °C ambient. |
Use Scenario: Hardening eSATA ports on automotive DVRs or industrial docking stations against hot-plug ESD events. IC Role / Device Role / Timing Role: Bidirectional ESD protection for 3 Gbps SATA differential signals, mounted at rear-panel connector with shortest possible trace length. Use Value: 0.4 Ω dynamic resistance minimizes clamping voltage overshoot during 15 kV contact discharge, preventing link training failure. |
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 NUP4201MR6T1G | 4-channel, bidirectional, 0.8 pF capacitance, ±12 kV IEC 61000-4-2, SOT-23-6 package | Larger capacitance limits use to ≤480 Mbps USB 2.0; lacks AEC-Q101 qualification and SWF | Select only for cost-sensitive non-automotive USB 2.0 designs where 0.8 pF is acceptable |
| Vishay VEML6030X01 | Single-channel, 0.35 pF, ±25 kV ESD rating, but no multi-channel integration; requires 4× placement | Higher ESD rating but increases BOM count, layout area, and routing complexity for quad-interface protection | Prefer only when extreme ESD margin (>±20 kV) is mandatory and space/layout overhead is acceptable |
Compared with NUP4201MR6T1G, PESD4USB5UTBS-QJ offers lower capacitance, higher ESD rating, and automotive qualification; versus VEML6030X01, it delivers integrated quad-channel protection with matched routing and reduced assembly cost.

FAQ
What is the maximum recommended trace length between PESD4USB5UTBS-QJ and the protected connector?
Trace length should not exceed 3 mm from device pad to connector pin to minimize inductance and preserve clamping effectiveness. Longer traces increase peak voltage overshoot during ESD events due to L·di/dt effects. The DFN2510D-10 footprint is optimized for direct edge-mount placement with zero stub routing.
Can PESD4USB5UTBS-QJ be used on bidirectional differential buses like USB 3.2 Gen 2?
Yes-its unidirectional architecture is applied per line (e.g., D+ and D− each get separate diodes), enabling full protection of bidirectional high-speed differential pairs. The 0.5 pF capacitance and symmetric clamping (±3.5 V) ensure signal integrity is maintained in both transmit and receive directions without DC bias disruption.
Does the 'n.c.' marking on pins 6, 7, 9, and 10 imply they must be left floating?
No-these pins are internally unconnected but may be tied to ground for mechanical reinforcement or thermal conduction, provided no electrical short is introduced. Nexperia's footprint recommendation permits grounding them to improve solder joint strength and heat dissipation without affecting ESD performance.
How does the snap-back behavior affect system power-up sequencing?
The snap-back characteristic only activates during ESD transients above ~6 V breakdown; it does not engage during normal 3.3 V or 5 V operation. No special power sequencing is required-the device remains in high-impedance state until an ESD event exceeds VBR, avoiding interference with link training or idle-state signaling.
