Product details
Overview
PESD5V0S1UA from Nexperia is a unidirectional ESD protection diode in SOD323 package, designed to safeguard one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), IEC 61000-4-5 surge (47 A), with 5 V reverse standoff voltage, 19 V clamping voltage at 47 A, and 480 pF capacitance at 1 MHz - deployed in USB data lines of portable electronics.
For engineers reviewing the PESD5V0S1UA datasheet, PESD5V0S1UA pinout, PESD5V0S1UA application, or PESD5V0S1UA equivalent, this page delivers verified electrical parameters, validated SOD323 terminal mapping, real-world protection use cases, and AEC-Q101-qualified alternatives for high-reliability signal-line transient suppression.
Technical Context
This device operates as a unidirectional TVS diode: it conducts only when forward-biased beyond its 6.2–7.3 V breakdown voltage (IR = 5 mA), clamping transients to ≤19 V at 47 A (8/20 µs pulse). Its low 0.3 µA leakage at 5 V enables minimal signal loading on low-power interfaces.
The SOD323 footprint supports compact placement near connectors, and its 345 K/W junction-to-ambient thermal resistance requires careful PCB copper layout per IEC 61000-4-2 test setup guidelines - especially minimizing trace inductance between protected line and ground return path.
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 3.3 V or 5 V logic lines. |
| Clamping Voltage | 19 V at 47 A (8/20 µs) - peak voltage seen by protected IC during worst-case surge; ensures downstream ICs rated ≥20 V survive. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - withstands human-body ESD events without degradation or failure. |
| Diode Capacitance | 480 pF at 1 MHz, 0 V - limits bandwidth impact on high-speed signals like USB 2.0 (480 Mbps); acceptable for <10 MHz analog or digital lines. |
| Peak Pulse Power | 890 W - energy-handling capability under standardized 8/20 µs surge; sufficient for industrial and automotive-level transient immunity. |
| Leakage Current | 0.3 µA at 5 V - negligible DC loading on battery-powered sensor or audio bias networks; avoids signal drift or power loss. |
| Breakdown Voltage | 6.8 V typical at 5 mA - precise turn-on threshold ensures early clamping while avoiding false triggering on normal signal peaks. |
Pinout & Package
SOD323 plastic surface-mounted package: 2-pin, 1.3 mm pitch, 1.7 × 1.25 × 0.95 mm body; marking bar denotes cathode (Pin 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground or low-impedance return path; carries full surge current during clamping; solder tab serves as primary thermal path. |
| 2 (A) | Anode | Connected to protected signal line; reverse-biased during normal operation; forward-conducts only during overvoltage events to shunt current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity testing, and ESD robustness - suitable for infotainment and ADAS interface protection. |
| Low clamping voltage (19 V @ 47 A) | Reduces stress on downstream transceivers and PHYs during surge events, extending lifetime in communication ports exposed to lightning-induced surges. |
| 480 pF capacitance at 1 MHz | Enables use on medium-speed serial buses (e.g., UART, I²C, SPI) without signal integrity degradation or timing skew. |
| 0.3 µA leakage at 5 V | Preserves battery life in always-on portable devices and avoids DC offset errors in precision analog front-ends. |
| SOD323 footprint | Supports automated placement and reflow in high-volume manufacturing; compatible with standard 0805-class pick-and-place equipment and stencil designs. |
Applications
| USB 2.0 Data Lines | Automotive Infotainment Interfaces |
|---|---|
|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in car head units against ESD from user insertion and cable coupling. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between signal line and chassis ground, activated only during positive transients relative to ground. Use Value: Prevents latch-up or gate oxide damage in USB transceivers while maintaining <1 ns response time and preserving signal rise/fall characteristics. |
Use Scenario: Shielding LIN bus or CAN FD auxiliary control lines in dashboard modules from electrostatic discharge during service or environmental exposure. IC Role / Device Role / Timing Role: Transient voltage suppressor mounted directly at connector entry point, referenced to vehicle ground plane. Use Value: Ensures compliance with ISO 10605 (25 kV air/30 kV contact) without adding series impedance or capacitance that would distort low-speed bus signaling. |
| Medical Sensor Signal Paths | Industrial HMI Touch Controllers |
|
Use Scenario: Guarding analog output lines of patient-monitoring ECG or SpO₂ sensors against operator ESD during clinical handling. IC Role / Device Role / Timing Role: Low-leakage unidirectional TVS placed inline with buffered analog outputs, grounded via shortest possible trace. Use Value: Maintains sub-µV baseline stability and avoids DC offset shifts caused by higher-leakage alternatives, critical for diagnostic accuracy. |
Use Scenario: Securing I²C or SPI lines connecting capacitive touch overlay to main controller in factory HMIs exposed to maintenance personnel ESD. IC Role / Device Role / Timing Role: Signal-line protector installed adjacent to touch controller IC, with dedicated ground pour beneath cathode pad. Use Value: Eliminates firmware lockups and ghost-touch events induced by ESD-induced bus glitches, improving mean time between failures (MTBF). |
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 clamping voltage (24 V @ 47 A), lower capacitance (30 pF), dual-channel configuration | Better suited for high-speed USB 3.0 or HDMI where low capacitance is critical; less effective for 5 V rail protection due to higher VCL | Select when protecting >1 Gbps differential pairs and board space allows dual-line integration |
| Vishay SMAJ5.0A | Higher power rating (400 W), larger SMA package, bidirectional configuration | Designed for AC-coupled or symmetric signal paths (e.g., RS-485); not optimized for single-ended low-voltage logic lines | Prefer for industrial fieldbus protection where polarity is undefined or bidirectional surges dominate |
Compared with NUP4105MR6T1G and SMAJ5.0A, PESD5V0S1UA offers tighter clamping (19 V vs. 24 V/36 V), smaller SOD323 footprint for dense layouts, and unidirectional behavior ideal for DC-biased signal lines - making it optimal for cost-sensitive, space-constrained 5 V interface protection.

FAQ
What is the maximum operating temperature for PESD5V0S1UA?
The PESD5V0S1UA has a maximum junction temperature of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance from junction to ambient is 345 K/W on standard FR4 PCB, so derating is required above 70 °C ambient to maintain reliability under repeated surge events.
Can PESD5V0S1UA protect bidirectional signal lines like I²C?
No - PESD5V0S1UA is unidirectional and only clamps positive transients relative to ground. For bidirectional lines such as I²C, a bidirectional variant like PESD5V0S1BA (same package, symmetrical clamping) must be used to protect both positive and negative excursions.
How does the 480 pF capacitance affect USB 2.0 signal integrity?
At 480 pF, PESD5V0S1UA introduces ~0.5 dB attenuation at 480 MHz but preserves eye diagram opening for USB 2.0 full-speed (480 Mbps) signals when placed with minimal stub length; layout optimization (ground vias, short traces) keeps jitter increase below 10 ps RMS.
Is PESD5V0S1UA compliant with RoHS and REACH?
Yes - PESD5V0S1UA meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin termination and halogen-free molding compound, as confirmed in Nexperia's official compliance documentation dated May 2023.
