Product details
Overview
PESD4USB5BTBR-QX 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, 0.22 pF channel capacitance, 0.5 Ω dynamic resistance, and operates with 5 V reverse standoff voltage in automotive-grade AEC-Q101 qualified DFN2510A-10 packaging.
For engineers reviewing the PESD4USB5BTBR-QX datasheet, PESD4USB5BTBR-QX pinout, PESD4USB5BTBR-QX application, or PESD4USB5BTBR-QX equivalent, key selection criteria include ultra-low capacitance for signal integrity preservation, snap-back clamping behavior for low-voltage rail protection, matched trace spacing for differential pair routing, and AEC-Q101 qualification for automotive infotainment and camera links.
Technical Context
This device implements a snap-back triggered silicon avalanche structure that achieves deep clamping at ≤±5.5 V under ±5 A transient conditions while maintaining sub-0.5 Ω dynamic resistance. Its bidirectional architecture enables symmetric protection on differential data lanes without polarity constraints.
The 0.22 pF typical diode capacitance per channel is measured at 1 MHz and 0 V bias, enabling minimal signal distortion on 10 Gbps USB 3.2 Gen 2 and HDMI 2.0 channels. The DFN2510A-10 package supports 0.5 mm trace spacing and pass-through PCB layout to preserve controlled impedance.
Key Specifications

| ESD Rating | ±15 kV per IEC 61000-4-2 level 4 (contact); ensures robust system-level immunity in handheld and automotive interface ports |
| Channel Capacitance | 0.22 pF (typ) at 1 MHz, 0 V; preserves signal integrity on 10 Gbps USB 3.2 and HDMI 2.0 differential pairs |
| Dynamic Resistance | 0.5 Ω (typ); minimizes clamping voltage overshoot during fast ESD transients |
| Reverse Standoff Voltage | 5 V; compatible with 3.3 V and 5 V high-speed interface supply rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.5 pF channel capacitance; ±12 kV IEC 61000-4-2; 6-pin SON package | Higher capacitance limits use to ≤5 Gbps interfaces; lacks AEC-Q101 qualification | Select when cost sensitivity outweighs 10 Gbps support and automotive qualification requirements |
| ESD56411D05-2/TR | 0.3 pF capacitance; ±20 kV ESD rating; 10-pin DFN same footprint but higher leakage (500 nA) | Superior ESD margin but higher signal loading; not AEC-Q101 qualified | Prefer for non-automotive industrial systems requiring maximum ESD headroom over signal fidelity |
Compared with TPD4E05U06DQAR and ESD56411D05-2/TR, PESD4USB5BTBR-QX uniquely balances 0.22 pF capacitance, ±15 kV ESD rating, and AEC-Q101 qualification in a 10-terminal DFN-making it the only option validated for automotive 10 Gbps USB 3.2 and HDMI 2.0 interfaces.

FAQ
What is the maximum data rate supported by PESD4USB5BTBR-QX without signal degradation?
PESD4USB5BTBR-QX supports up to 10 Gbps (USB 3.2 Gen 2) with verified signal integrity: its 0.22 pF channel capacitance introduces <0.02 UI jitter at 3.125 Gbps and maintains <0.3 dB insertion loss up to 5 GHz, as confirmed in Nexperia's application note AN11614 for high-speed interface protection.
How does the snap-back behavior affect system-level ESD performance?
The snap-back structure reduces clamping voltage to ≤±5.5 V at ±5 A transient current, lowering stress on downstream PHY ICs by >30% versus conventional TVS diodes. This behavior is validated via TLP testing per ANSI/ESD STM5.5.1-2008 and prevents latch-up in sensitive SerDes receivers during IEC 61000-4-2 contact discharges.
Can PESD4USB5BTBR-QX be used on single-ended interfaces like UART or I²C?
No-its 0.22 pF capacitance and 5 V standoff voltage are optimized for differential high-speed protocols (USB 3.2, HDMI, GMSL). For single-ended interfaces, Nexperia recommends PESD5V0S1BA (0.5 pF, 5 V) or PESD1CAN (15 pF, 24 V), which provide appropriate capacitance-to-voltage ratios and lower leakage for low-speed control lines.
Why are pins 6, 7, 9, and 10 marked 'n.c.' and what happens if they are connected?
These pins have no internal connection and serve only as mechanical anchors and thermal relief. Connecting them risks parasitic coupling into adjacent high-speed traces, increases solder voiding risk during reflow, and may cause unintended ground loops. Nexperia's footprint guide (Fig. 10) explicitly requires leaving them unconnected and unmasked in solder paste stencil design.
