Product details
Overview
PESD5V0L1UA-Q from Nexperia is a low-capacitance unidirectional ESD protection diode in SOD323 (SC-76) package, designed to protect single high-speed signal lines against IEC 61000-4-2 level 4 ESD events up to ±26 kV contact discharge. It features 25 pF typical capacitance, 12 V clamping voltage at 3.5 A, and 10 nA reverse leakage at 5 V standoff, enabling use in USB 2.0, SIM card, and FireWire interfaces.
For engineers reviewing the PESD5V0L1UA-Q datasheet, PESD5V0L1UA-Q pinout, PESD5V0L1UA-Q application, or PESD5V0L1UA-Q equivalent, key selection criteria include low capacitance for signal integrity, AEC-Q101 qualification for automotive reliability, unidirectional polarity handling, and SOD323 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a unidirectional transient voltage suppressor, leveraging silicon avalanche diode structure to clamp ESD transients while maintaining low dynamic impedance (30 Ω differential resistance) and fast response (<1 ns rise time per IEC 61000-4-2). Its 5 V reverse standoff voltage aligns with standard 3.3 V/5 V logic rails.
The SOD323 package enables placement within 2 mm of I/O connectors, minimizing inductance in the protection path. Clamping occurs at 12 V under 3.5 A 8/20 µs surge, limiting voltage overshoot on protected lines without interfering with normal signal swing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Ensures no conduction during normal 3.3 V/5 V signal operation |
| Diode Capacitance | 25 pF (typ.) at 1 MHz - Preserves signal integrity on USB 2.0 and FireWire data lines |
| Clamping Voltage | 12 V at 3.5 A - Limits transient overvoltage to safe levels for downstream ICs |
| ESD Rating | ±26 kV contact discharge (IEC 61000-4-2 Level 4) - Meets stringent industrial and automotive immunity requirements |
| Leakage Current | 10 nA at 5 V - Minimizes power loss and avoids false triggering in battery-powered devices |
| Breakdown Voltage | 6.8 V (typ.) at 5 mA - Provides margin above 5 V VRWM while enabling rapid turn-on during transients |
| Peak Pulse Power | 42 W - Sustains short-duration surges without thermal failure |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-pin, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode marked by bar on top surface.

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 NUP4105MR6T1G | Higher 35 pF capacitance; 15 V clamping at 3.5 A; SOT-523 package | Less suitable for >100 Mbps data lines; larger 1.6 mm × 1.6 mm footprint | Select when board space allows larger package and 35 pF is acceptable for lower-speed interfaces |
| Vishay VEML5010-001 | 20 pF capacitance but only 12 kV ESD rating; non-AEC-Q101; SOD-323 | Lacks automotive qualification; insufficient for ISO 10605-compliant systems | Use only in consumer-grade portable electronics where AEC-Q101 is not required |
Compared with NUP4105MR6T1G and VEML5010-001, PESD5V0L1UA-Q uniquely combines AEC-Q101 qualification, 25 pF capacitance, and ±26 kV ESD rating in the compact SOD323 footprint-making it optimal for space-constrained automotive and high-speed data line protection.

FAQ
What is the maximum operating temperature for PESD5V0L1UA-Q?
The PESD5V0L1UA-Q supports continuous operation up to 150 °C junction temperature and −55 °C to +150 °C ambient temperature range, validated per AEC-Q101 thermal cycling and high-temperature operating life tests. This enables deployment in engine bay–adjacent infotainment modules and under-hood telematics units without derating.
Can PESD5V0L1UA-Q protect bidirectional data lines like USB D+/D−?
Yes-two PESD5V0L1UA-Q devices can be used in back-to-back configuration (anode-to-anode) to provide bidirectional protection on differential pairs. Each device handles one polarity, preserving 25 pF capacitance per line and meeting USB-IF ESD test requirements when placed within 3 mm of the connector.
How does the 12 V clamping voltage relate to 3.3 V I/O protection?
With a 12 V clamping voltage at 3.5 A, the device limits transient overshoot to 12 V-providing 8.7 V margin above a 3.3 V rail. This exceeds the typical 7 V absolute maximum rating of 3.3 V logic I/O pins, preventing gate oxide rupture and ensuring reliable protection without requiring additional series impedance.
Is the SOD323 footprint compatible with automated optical inspection (AOI)?
Yes-the SOD323 package has standardized dimensions (1.7 mm × 1.25 mm) and visible cathode marking bar, enabling reliable AOI detection of solder joint quality, component presence, and orientation. Reflow footprint per Figure 8 ensures ≥75% solder paste coverage and <50 µm lateral misalignment tolerance.
