Product details
Overview
PESD5V0S1USF from Nexperia is a unidirectional ESD protection diode in a DSN0603-2 (SOD962) package, designed to protect one signal line against electrostatic discharge up to 30 kV (IEC 61000-4-2 Level 4), with 5 V reverse standoff voltage, 35 pF typical capacitance, and ultra-low 1 nA leakage current - deployed in high-density portable electronics interfaces.
For engineers reviewing the PESD5V0S1USF datasheet, PESD5V0S1USF pinout, PESD5V0S1USF application, or PESD5V0S1USF equivalent, key selection criteria include clamping voltage under 3.5 A surge (11 V), dynamic resistance of 0.7 Ω, and compatibility with space-constrained PCB layouts requiring sub-0.6 mm × 0.3 mm footprints.
Technical Context
This device operates as a single-line unidirectional transient voltage suppressor, leveraging silicon PN-junction clamping behavior. Its IEC 61000-4-2 compliance (±30 kV contact/air discharge) and IEC 61643-321 surge rating (3.5 A, 8/20 µs) confirm suitability for interface-level ESD hardening on data lines with fixed polarity relative to ground.
Clamping performance is characterized by VCL = 11 V at IPPM = 3.5 A and VBR = 6–8 V at IR = 1 mA, with low dynamic resistance (0.7 Ω) ensuring rapid voltage suppression during fast transients. The 35–42 pF capacitance at 1 MHz and 0 V bias supports high-speed signal integrity in USB 2.0, audio, and sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction begins; defines safe signal swing range for protected line. |
| Clamping Voltage | 11 V at 3.5 A - Peak voltage seen by downstream circuitry during worst-case 8/20 µs surge; limits stress on IC inputs. |
| Diode Capacitance | 35 pF (typ) at 1 MHz - Low enough to avoid signal distortion in 480 Mbps USB 2.0 or 24 MHz I²S audio paths. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact) - Meets industrial and consumer immunity requirements without external shielding. |
| Leakage Current | <1 nA at 5 V - Negligible DC loading on high-impedance sensor or battery-backed signal lines. |
| Peak Pulse Power | 35 W - Sustains transient energy without thermal runaway under repeated 8/20 µs surges. |
| Package Dimensions | 0.6 × 0.3 × 0.3 mm - Enables placement within 1 mm of USB-C, microSD, or headphone jack connectors. |
Pinout & Package
Encapsulated in the leadless DSN0603-2 (SOD962) surface-mount package - 2-terminal, 0.4 mm pitch, body size 0.6 mm × 0.3 mm × 0.3 mm, with cathode indicated by a visible marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or low-impedance return path; carries surge current during positive transients on protected line. |
| 2 | Anode (A) | Connected to the signal line requiring protection; conducts only when line voltage exceeds VRWM + VBR relative to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Protects only positively-polarized signal lines (e.g., USB D+, HDMI TMDS+), eliminating false triggering on negative excursions. |
| Ultra-low leakage current | <1 nA at 5 V enables use on battery-powered sensor nodes and always-on wake-up lines without measurable drain. |
| Sub-1 mm² footprint | 0.6 mm × 0.3 mm body allows integration directly adjacent to high-speed connector pads, minimizing inductance in ESD current path. |
| 30 kV ESD immunity | Exceeds IEC 61000-4-2 Level 4 requirement, reducing need for secondary board-level shielding in handheld devices. |
| Dynamic resistance of 0.7 Ω | Ensures fast response (<1 ns) and minimal overshoot during nanosecond-scale ESD events per ANSI/ESD STM5.5.1. |
Applications
| USB 2.0 Interface Protection | Smartphone Audio Jack ESD Guard |
|---|---|
Use Scenario: Protecting D+ and D− lines of a USB 2.0 port against user-handling ESD during cable insertion. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between connector and USB transceiver IC, referenced to system ground. Use Value: 35 pF capacitance avoids signal integrity degradation at 480 Mbps; 11 V clamping prevents damage to PHY input stages rated for 3.3 V I/O. | Use Scenario: Shielding 3.5 mm TRRS audio jack contacts (MIC, L/R, GND) from ESD during headset plugging/unplugging. IC Role / Device Role / Timing Role: One PESD5V0S1USF per signal line (e.g., MIC+), anode tied to line, cathode to ground. Use Value: 1 nA leakage preserves battery life in always-listening voice assistant modes; 0.6 mm × 0.3 mm size fits tight jack-side PCB real estate. |

IC Role / Device Role / Timing Role: Single-line protector on 0–5 V ratiometric sensor output, positioned at connector entry point. Use Value: 5 V VRWM matches common sensor supply rails; 30 kV air-discharge rating ensures robustness in factory environments with synthetic flooring. | Use Scenario: Protecting differential ECG electrode inputs in handheld patient monitors against accidental static discharge during clinical handling. IC Role / Device Role / Timing Role: Two devices per channel (one per input), configured unidirectionally to clamp positive transients toward ground. Use Value: Ultra-low 1 nA leakage avoids DC offset errors in high-gain instrumentation amplifiers; 11 V clamping stays below front-end ADC overvoltage limits. |
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 12 V clamping at 3.5 A; 50 pF capacitance; SOT-523 package (1.25 × 0.85 mm). | Less suitable for USB 2.0 due to higher capacitance; better for lower-speed RS-232 or GPIO lines. | Select when board layout allows larger footprint and signal bandwidth < 10 MHz. |
| Vishay VEML6030X01 | Not applicable - optical ambient light sensor; invalid alternative. | N/A | Excluded: not an ESD protection device. |
Compared with NUP4105MR6T1G, PESD5V0S1USF offers 15% lower clamping voltage and 30% less capacitance in a footprint 75% smaller - critical for miniaturized USB and audio interfaces where layout area and signal fidelity are constrained.

FAQ
What is the maximum continuous reverse voltage this diode can withstand?
The PESD5V0S1USF has a reverse standoff voltage (VRWM) of 5 V, meaning it blocks up to 5 V DC or steady-state AC signals without conducting. This rating is verified per IEC 61000-4-2 test conditions at 25 °C ambient and defines the upper limit of normal operating voltage on the protected line.
Can this device protect bidirectional signal lines like USB D+/D− simultaneously?
No - PESD5V0S1USF is unidirectional and protects only one polarity. For full USB 2.0 differential pair protection, two devices are required: one per line (D+ and D−), each with anode to signal and cathode to ground. Bidirectional protection would require a different part such as PESD5V0X1BC.
How does the 0.7 Ω dynamic resistance impact ESD suppression performance?
A dynamic resistance of 0.7 Ω (measured per TLP at 10 A) ensures minimal voltage overshoot during sub-nanosecond ESD events. It directly reduces clamped voltage (VCL = VBR + IPP × Rdyn), enabling tighter protection margins for 3.3 V or 1.8 V I/O circuits without additional series impedance.
Is this component suitable for automotive applications?
No - PESD5V0S1USF is not AEC-Q200 qualified and lacks automotive-grade qualification, temperature cycling validation, or extended lifetime reliability testing. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use requires customer-led validation for any vehicle-mounted implementation.
