Product details
Overview
PESD5V0X1UALD from Nexperia is a unidirectional ESD protection diode in SOD882D (DFN1006D-2) package, designed to protect single high-speed signal lines with 1.55 pF capacitance, 5.5 V reverse standoff voltage, and 9 V clamping voltage at 2 A surge current. It is used in HDMI, USB, and Ethernet interfaces where low-capacitance transient suppression is critical.
For engineers reviewing the PESD5V0X1UALD datasheet, PESD5V0X1UALD pinout, PESD5V0X1UALD application, or PESD5V0X1UALD equivalent, key selection criteria include ultra-low capacitance for signal integrity, side-wettable flanks for solder inspection, IEC 61000-4-2 Level 4 (±15 kV) ESD rating, and 0.37 mm profile for space-constrained portable designs.
Technical Context
This unidirectional TVS diode operates as a clamping device between signal line and ground, conducting only when reverse voltage exceeds breakdown (5.8–7.5 V), enabling precise protection of positive-polarity or negative-polarity signals without forward conduction during normal operation.
Its dynamic resistance of 0.15 Ω at 10 A TLP pulse ensures rapid energy dissipation, while the 1 nA leakage at 5.5 V supports low-power interface compatibility. The SOD882D package integrates solderable side pads for automated optical inspection and thermal performance matching PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5.5 V - Maximum continuous operating voltage before leakage rises significantly; sets upper limit for protected line DC bias. |
| Diode Capacitance | 1.55 pF (typ.) at 1 MHz, 0 V - Enables minimal signal distortion on >1 Gbps data lines like HDMI 2.0 and USB 3.1. |
| Clamping Voltage | 9 V at 2 A, 8/20 µs - Limits transient voltage seen by downstream ICs during IEC 61000-4-5 surge events. |
| ESD Withstand | ±15 kV per IEC 61000-4-2 Contact Discharge - Meets industrial and consumer immunity requirements without external circuitry. |
| Leakage Current | 1 nA (typ.) at 5.5 V - Prevents loading of high-impedance analog or reference signal paths. |
| Package Dimensions | 1.0 × 0.6 × 0.37 mm - Ultra-compact footprint compatible with fine-pitch routing and thin-profile mobile PCBs. |
Pinout & Package
The PESD5V0X1UALD is housed in a leadless DFN1006D-2 (SOD882D) plastic package with visible side-wettable flanks, 0.65 mm pitch, and cathode indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground; conducts ESD current from protected line (pin 2) to GND during overvoltage events. |
| 2 (A) | Anode | Connected to the signal line requiring protection; blocks DC current in normal operation due to unidirectional polarity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 1.55 pF enables use on 10/100/1000BASE-T Ethernet and HDMI 2.0 channels without degrading eye diagram margin. |
| Solderable side pads | Visible flank geometry supports automated optical inspection (AOI) and improves reflow process yield in high-volume SMT lines. |
| Low clamping voltage | 9 V clamping at 2 A limits stress on sensitive transceivers such as USB Type-C PHYs and HDMI sink ICs. |
| Small height profile | 0.37 mm typical height allows integration beneath connectors or in stacked-board assemblies with tight Z-axis constraints. |
Applications
| HDMI Signal Line Protection | USB 3.1 Data Lane Protection |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESDE05C1W | Higher capacitance (2.0 pF typ.), same 5.5 V VRWM and ±15 kV ESD rating. | Marginally reduced bandwidth suitability for >5 Gbps links; otherwise drop-in for cost-sensitive designs. | Select when board-level ESD testing passes with 2.0 pF loading and procurement favors ON Semi distribution channels. |
| Vishay VEML5010 | Lower clamping voltage (7.5 V), but higher leakage (5 nA) and larger SOD-523 package (1.2 × 0.8 mm). | Better transient suppression for low-voltage logic, but unsuitable for ultra-thin or ultra-dense layouts. | Prefer for 3.3 V systems needing tighter clamping, provided height and footprint allowances exist. |
Compared with ESDE05C1W and VEML5010, PESD5V0X1UALD delivers the lowest capacitance (1.55 pF) in the smallest footprint (1.0 × 0.6 mm), making it optimal for next-generation mobile and high-speed serial interfaces where signal fidelity and board area are constrained.

FAQ
What is the maximum recommended PCB trace length between PESD5V0X1UALD and the protected connector?
For optimal ESD performance, the trace from the protected line to the anode (pin 2) must be ≤2 mm, and the ground path from cathode (pin 1) to the nearest solid ground plane must be direct and ≤3 mm. Longer traces increase inductance, raising clamped voltage during fast transients and risking IC damage.
Can PESD5V0X1UALD protect bidirectional signal lines like I²C or UART?
No - PESD5V0X1UALD is unidirectional and only clamps positive transients relative to ground. For bidirectional lines, two devices must be placed back-to-back (anode-to-anode) or a dedicated bidirectional ESD array like PESD5V0R1B must be used to ensure protection during both polarities of ESD events.
Does the SOD882D package support IPC-A-610 Class 3 automated optical inspection?
Yes - the side-wettable flanks (SWF) of the SOD882D package provide visible solder fillets under standard AOI lighting angles, enabling reliable detection of head-in-pillow, insufficient solder, and bridging defects per IPC-A-610 Rev H Class 3 requirements.
What is the thermal derating behavior above 85 °C ambient temperature?
Peak pulse current (IPPM) remains rated at 2 A up to 125 °C ambient; beyond that, linear derating applies from 2 A to 0 A between 125 °C and 150 °C junction temperature, per IEC 61000-4-5 test conditions and Nexperia's limiting values table.
