Product details
Overview
PESD15VU1UT-Q from Nexperia is a unidirectional ultra-low-capacitance ESD protection diode in SOT23 package, designed to protect single high-speed data lines against 30 kV contact ESD (IEC 61000-4-2 Level 4) and 200 W surge pulses (IEC 61000-4-5), with 0.6 pF typical capacitance, 15 V reverse standoff voltage, and AEC-Q101 qualification for automotive Ethernet interfaces.
For engineers reviewing the PESD15VU1UT-Q datasheet, PESD15VU1UT-Q pinout, PESD15VU1UT-Q application, or PESD15VU1UT-Q equivalent, this device is selected for high-fidelity signal integrity preservation in 10/100/1000BASE-T, FireWire, and differential-mode LAN transceivers where sub-1 pF capacitance and low clamping voltage (<53 V at 5 A) are critical.
Technical Context
This device implements a dual-diode architecture: one ESD protection diode (Pin 1–Pin 3) and one compensation diode (Pin 2–Pin 3), enabling ultra-low net capacitance (0.6 pF typ.) between protected line and ground while maintaining robust clamping performance. Its unidirectional configuration supports asymmetric transient suppression on single-ended lines.
It operates within −65 °C to +150 °C ambient range, features 17.1–20.3 V breakdown voltage at 5 mA, and delivers 28 V clamping at 1 A IPP - optimized for fast-rising ESD events (0.6–1 ns rise time) and 8/20 µs surge waveforms. The common-anode (Pin 3) topology simplifies PCB layout for single-line protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V max - ensures no leakage or conduction during normal 15 V rail operation on protected line |
| Diode Capacitance | 0.6 pF typ. at 1 MHz, 0 V bias - preserves signal integrity up to multi-GHz frequencies in USB 3.x, Ethernet PHYs |
| Clamping Voltage | 53 V max at 5 A IPPM - limits transient overvoltage to safe levels for downstream 3.3 V or 5 V transceivers |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds automotive and industrial immunity requirements |
| Peak Pulse Power | 200 W (8/20 µs) - handles lightning-induced surges per IEC 61000-4-5 without degradation |
| Breakdown Voltage | 18.9 V typ. at 5 mA - provides clear margin above 15 V VRWM for reliable turn-on during transients |
| Junction Temperature | 150 °C max - supports under-hood automotive deployment with sustained thermal stress |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body; compatible with standard reflow and wave soldering footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | K2 (cathode) | Compensation diode cathode - reduces net capacitance when used with Pin 3 common anode |
| 3 | CA (common anode) | Shared anode node tied to system ground - enables low-capacitance series-cathode configuration |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance architecture | 0.6 pF typ. net capacitance between line and ground - minimizes signal distortion in >100 MHz data links |
| Automotive-grade reliability | AEC-Q101 qualified - validated for temperature cycling, HBM (10 kV), and mechanical shock in vehicle ECUs |
| Dual-cathode topology | Separate K1/K2 pins with shared CA - enables precise capacitance tuning and differential-mode protection via anti-parallel pairing |
| Low clamping resistance | 225 Ω differential resistance - ensures rapid voltage collapse during ESD events without oscillation |
| Surge-rated power handling | 200 W peak pulse (8/20 µs) - sustains multiple surge events without parameter shift or failure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ultra-low-capacitance ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | 0.8 pF typ. capacitance; 12 V VRWM; 30 kV ESD rating; SOT-23 package | Lower standoff voltage limits use in 15 V systems; higher capacitance impacts >500 MHz signals | Select when cost sensitivity outweighs 0.2 pF capacitance penalty and 15 V operation is not required |
| Vishay ESDEFL15V | 0.5 pF typ. capacitance; 15 V VRWM; 25 kV ESD rating; SOD-323 package | Smaller SOD-323 footprint increases routing density but reduces thermal mass for surge dissipation | Prefer for space-constrained RF front-ends where 5 kV lower ESD margin is acceptable |
Compared with NUP4105MR6T1G and ESDEFL15V, PESD15VU1UT-Q uniquely balances 15 V standoff, 30 kV ESD immunity, and 0.6 pF capacitance in SOT23 - making it optimal for automotive Ethernet PHY protection where all three parameters are simultaneously constrained.

FAQ
What is the recommended PCB layout for PESD15VU1UT-Q in Ethernet applications?
Place the device within 2 mm of the Ethernet connector, route protected line directly to Pin 1, connect Pin 3 to solid ground plane via shortest possible trace, and avoid vias or stubs on the protected path. Use dedicated ground return path separate from power ground to minimize inductance and ensure <53 V clamping under 5 A ESD current.
Can PESD15VU1UT-Q be used for bidirectional protection?
Yes - two devices in anti-parallel configuration (Pin 1 of Device A to Pin 2 of Device B, both Pin 3s to ground) provide symmetrical clamping for differential lines like Ethernet TX+/TX−. This achieves effective bidirectional protection while retaining 0.6 pF per path and full 30 kV ESD rating.
Does PESD15VU1UT-Q require external biasing or control signals?
No - it is a passive, unidirectional Zener-type ESD diode requiring no power supply, enable pin, or configuration. It remains non-conductive below 15 V VRWM and automatically clamps transients above breakdown voltage without latency or control overhead.
How does its AEC-Q101 qualification impact design validation?
AEC-Q101 qualification confirms successful completion of stress tests including temperature cycling (−40 °C to +125 °C, 1000 cycles), high-temperature operating life (1000 h at 150 °C), and ESD (HBM 2 kV, MM 200 V), eliminating need for redundant qualification testing in automotive programs and reducing time-to-certification.
