Product details
Overview
PESD15VS2UAT from Nexperia is a unidirectional double ESD protection diode in common-cathode SOT23 configuration, designed to protect two data lines against IEC 61000-4-2 level 4 ESD (±30 kV contact) and IEC 61000-4-5 surge (5 A, 8/20 µs). It features 15 V reverse standoff voltage, 32 pF typical capacitance at 1 MHz, and ultra-low 1 nA reverse leakage - ideal for high-speed USB 2.0 and HDMI signal line protection.
For engineers reviewing the PESD15VS2UAT datasheet, PESD15VS2UAT pinout, PESD15VS2UAT application, or PESD15VS2UAT equivalent, key selection criteria include clamping voltage under 40 V at 5 A surge, sub-70 pF capacitance for minimal signal distortion, common-cathode dual-anode topology for ground-referenced bidirectional line protection, and SOT23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a dual-anode, single-common-cathode structure enabling independent unidirectional protection of two separate signal paths referenced to ground. Each diode channel exhibits identical electrical characteristics: 17.6–18.4 V breakdown voltage at 5 mA, 40 V clamping voltage at 5 A peak pulse current, and 225 Ω differential resistance.
Its transient response conforms strictly to IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) standards, with validated 160 W peak pulse power handling capability and thermal derating down to 0.4× rated power at 150 °C junction temperature - ensuring robust operation across industrial ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - maximum continuous operating voltage before conduction begins; ensures no interference with 3.3 V or 5 V logic signaling. |
| Clamping Voltage | 40 V at 5 A (8/20 µs) - limits transient overvoltage to safe levels for downstream ICs such as USB transceivers or HDMI receivers. |
| Diode Capacitance | 32 pF typical (0–15 V, 1 MHz) - low enough to avoid signal integrity degradation on 480 Mbps USB 2.0 differential pairs. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds industrial immunity requirements for front-panel connectors. |
| Peak Pulse Power | 160 W (8/20 µs) - sustains high-energy surges without failure, supporting EN 61000-4-5 compliance testing. |
| Reverse Leakage | 1 nA at 15 V - negligible DC loading on sensitive analog or reference lines. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch), optimized for automated reflow assembly and compact PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 (A1) | Input terminal for first protected data line; conducts during positive transients to common cathode (pin 3). |
| 2 | Anode 2 (A2) | Input terminal for second protected data line; operates independently but shares cathode return path. |
| 3 | Common Cathode (CC) | Shared low-impedance ground return path for both diodes; must connect directly to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual-diode architecture | Enables simultaneous protection of two ground-referenced signal lines using single-component footprint and shared ground path. |
| Ultra-low 1 nA reverse leakage | Maintains signal integrity on high-impedance sensor inputs or precision reference nodes without DC offset error. |
| 32 pF typical capacitance | Preserves rise/fall times on 480 Mbps USB 2.0 signals with <1% eye diagram closure penalty. |
| 160 W peak pulse power rating | Withstands repeated 5 A surge events per IEC 61000-4-5 without parameter shift or bond wire failure. |
| ±30 kV ESD contact rating | Exceeds IEC 61000-4-2 Level 4 by 50%, providing margin for connector wear and environmental aging effects. |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
|
Use Scenario: Protection of D+ and D− pins on USB 2.0 host/device connectors exposed to user-handling ESD.

| Industrial Serial Interface | Audio Line Input |
|

IC Role / Device Role: Common-cathode dual diode guarding differential pair against cable-induced surges. Use Value: Limits clamped voltage to ≤40 V during 5 A 8/20 µs surge, preserving transceiver input stage reliability. |
Use Scenario: Shielding analog audio input jacks (e.g., 3.5 mm TRS) from user-touch ESD in consumer AV receivers. IC Role / Device Role: Low-capacitance clamp on left/right channel inputs referenced to chassis ground. Use Value: Adds <0.5 dB insertion loss at 20 kHz while blocking >30 kV discharges without audible pop artifacts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher 20 V VRWM, 60 pF typical capacitance, 45 V clamping at 5 A | Better suited for 12 V automotive bus lines; less optimal for high-speed USB due to higher capacitance | Select when protecting 5–12 V industrial buses where speed is secondary to voltage margin |
| Vishay ESDE0402-15B | Same 15 V VRWM, but bidirectional configuration (±15 V), 25 pF capacitance, 30 V clamping | Supports AC-coupled or bipolar signal lines (e.g., RS-232); lacks common-cathode advantage for ground-referenced designs | Prefer for legacy serial interfaces requiring symmetric clamping, not for USB/HDMI with ground-referenced topology |
Compared with NUP4201MR6T1G and ESDE0402-15B, PESD15VS2UAT uniquely balances low capacitance, ground-referenced dual-anode routing, and tight 40 V clamping - making it optimal for modern high-speed digital interfaces where PCB layout efficiency and signal fidelity are critical.

FAQ
What is the maximum recommended PCB trace length between PESD15VS2UAT and the protected connector?
For optimal ESD suppression, the trace from the protected line to pin 1 or pin 2 must be ≤3 mm, and the common-cathode (pin 3) trace to solid ground plane must be ≤2 mm with ≥2 vias. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot beyond 40 V during 30 kV ESD events.
Can PESD15VS2UAT protect bidirectional data lines like I²C?
No - its unidirectional common-cathode architecture only clamps positive transients toward ground. For bidirectional lines such as I²C SDA/SCL, a bidirectional device like ESDE0402-15B or PESD5V0S1BA is required to suppress both positive and negative ESD pulses without disrupting DC bias.
Does PESD15VS2UAT require external series impedance for proper operation?
No external resistor is needed. Its 225 Ω differential resistance and 15 V standoff voltage allow direct placement between signal line and ground. However, a 0 Ω or 10 Ω series resistor may be added upstream to limit diode current during sustained overvoltage, though not required for standard IEC 61000-4-2/4-5 compliance.
Is PESD15VS2UAT qualified for automotive applications?
No - this variant is non-automotive qualified per Nexperia's revision history. Automotive-grade equivalents (e.g., PESD15VS2UAT-Q) undergo AEC-Q200 stress testing and feature extended temperature range (−40 °C to +125 °C) and enhanced surge robustness; use only the -Q suffix version in vehicle ECUs or infotainment systems.
