Product details
Overview
PESD5V0S1UJ from Nexperia is a unidirectional ESD protection diode in SC-90 (SOD323F) package, designed to protect one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), IEC 61000-4-5 surge (47 A, 8/20 µs), with 5 V reverse standoff voltage, 19 V clamping voltage at 47 A, and 480 pF capacitance - deployed in USB, HDMI, and audio interface lines of portable electronics.
For engineers reviewing the PESD5V0S1UJ datasheet, PESD5V0S1UJ pinout, PESD5V0S1UJ application, or PESD5V0S1UJ equivalent, key selection criteria include clamping voltage under 47 A surge, sub-500 pF capacitance for high-speed data lines, AEC-Q101 qualification for automotive-grade reliability, and SOD323F footprint compatibility with space-constrained PCB layouts.
Technical Context
This unidirectional TVS diode operates as a low-leakage (0.3 µA @ 5 V), fast-response clamp that conducts only when reverse voltage exceeds 6.2 V breakdown threshold, limiting transient energy by diverting surge current to ground via its cathode-anode path. Its 290 K/W junction-to-ambient thermal resistance requires careful PCB copper area design for sustained pulse handling.
The device follows IEC 61000-4-2 and IEC 61000-4-5 compliance protocols, with clamping performance validated at 9.8 V (5 A), 13.5 V (25 A), and 19 V (47 A) - enabling robust protection on single-ended, ground-referenced signal paths where polarity is fixed (e.g., VBUS, UART TX, I²C SDA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction; ensures no interference with 3.3 V or 5 V logic signaling. |
| Clamping Voltage (IPP = 47 A) | 19 V - Peak voltage seen by protected IC during full IEC 61000-4-5 surge; limits stress on downstream transceivers. |
| Diode Capacitance | 480 pF @ 1 MHz - Low enough for USB 2.0 (480 Mbps) and HDMI DDC lines without signal integrity degradation. |
| ESD Withstand | ±30 kV contact discharge - Meets IEC 61000-4-2 Level 4, eliminating need for external spark gaps in handheld device interfaces. |
| Peak Pulse Power | 890 W @ 8/20 µs - Sustains high-energy surges without thermal runaway when mounted per recommended FR4 footprint. |
| Leakage Current | 0.3 µA @ VRWM - Minimizes standby power loss in battery-powered systems such as Bluetooth headsets and wearables. |
| Breakdown Voltage | 6.2–7.3 V @ 5 mA - Tight tolerance ensures predictable turn-on behavior across temperature and process variation. |
Pinout & Package
Package: SC-90 (SOD323F), plastic surface-mounted, 2-lead, 1.7 mm × 1.25 mm × 0.7 mm body; marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or low-impedance return path; carries full surge current during clamping event. |
| 2 | Anode (A) | Connected to protected signal line; reverse-biased during normal operation, forward-biased during negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive environments including temperature cycling (-55 °C to +150 °C) and mechanical shock, enabling use in infotainment and ADAS sensor interfaces. |
| Low 480 pF capacitance | Preserves signal rise/fall times on 100+ Mbps serial links without requiring equalization or retiming. |
| 19 V clamping at 47 A | Provides margin below typical 24 V rail overvoltage thresholds in industrial control I/O modules. |
| 0.3 µA leakage @ 5 V | Enables direct placement on always-on sensor bias lines (e.g., MEMS microphone VDDIO) without measurable current drain. |
| SOD323F footprint | Compatible with standard reflow profiles and automated optical inspection (AOI); enables 0201-equivalent board density with improved thermal mass vs. 0201 MLV. |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 ports in docking stations against ESD from user insertion/removal. IC Role / Device Role / Timing Role: Unidirectional voltage clamp placed within 3 mm of USB connector, shunting ESD current to chassis ground before it reaches USB transceiver. Use Value: Prevents latch-up or gate oxide damage in USB PHY ICs while maintaining <1 ns response time and <500 pF loading. | Use Scenario: Safeguarding HDMI Display Data Channel (DDC) lines (SCL/SDA) in set-top boxes exposed to field-service ESD events. IC Role / Device Role / Timing Role: Reverse-biased protection element on 5 V-tolerant I²C bus, activated only during positive transients exceeding 6.2 V. Use Value: Maintains I²C communication integrity up to 400 kHz with no DC loading impact due to 0.3 µA leakage. |
| Automotive Infotainment Audio | Portable Medical Sensor Interface |
Use Scenario: Shielding analog audio input/output lines (e.g., AUX-IN, headphone jack) in car head units from cable-induced ESD. IC Role / Device Role / Timing Role: Cathode-to-ground configuration protecting unidirectional analog signals referenced to vehicle chassis ground. Use Value: Achieves AEC-Q101 compliance and 30 kV ESD immunity without degrading THD+N (<0.01%) in 20 Hz–20 kHz band. | Use Scenario: Securing SPI clock/MOSI lines between microcontroller and disposable biosensor cartridge in point-of-care diagnostics. IC Role / Device Role / Timing Role: Signal-line protector on low-power, battery-operated digital interface with strict 1 µA total system leakage budget. Use Value: Adds only 0.3 µA leakage and 480 pF load, enabling reliable 10 Mbps SPI operation with <100 ps jitter increase. |
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 SZ1.5SMC5.0A | Higher clamping voltage (25 V @ 47 A), larger SMC package (7.1 mm × 6.2 mm), 1500 W peak power | Targeted at higher-energy AC/DC power rail protection, not high-speed data lines | Select only if board space allows and signal bandwidth <10 Mbps |
| Vishay VE15A5.0 | 5.0 V standoff, but bidirectional configuration; 15 V clamping @ 47 A; 0.55 nF capacitance | Designed for symmetric signal lines (e.g., RS-485), unsuitable for unidirectional VBUS or analog outputs | Use only where differential or AC-coupled signals require symmetrical clamping |
Compared with SZ1.5SMC5.0A and VE15A5.0, PESD5V0S1UJ delivers optimal trade-off of ultra-low capacitance (480 pF), compact SOD323F size, and precise 5 V standoff - making it uniquely suited for high-density, high-speed consumer and automotive data interfaces where layout space and signal fidelity are constrained.

FAQ
What is the maximum operating temperature for PESD5V0S1UJ?
The PESD5V0S1UJ 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 290 K/W on standard FR4 PCB, so derating is required above 70 °C ambient for repeated surge events.
Can PESD5V0S1UJ be used on bidirectional signal lines like I²C?
No - PESD5V0S1UJ is unidirectional and only protects against positive transients on the anode relative to cathode. For bidirectional lines such as I²C, a bidirectional variant like PESD5V0S2UJ (dual-line, symmetric clamping) must be used to avoid forward conduction during normal signal swings.
How does the 480 pF capacitance affect USB 2.0 signal integrity?
At 480 pF, the device adds <0.5 UI jitter to 480 Mbps USB 2.0 eye diagrams when placed per layout guidelines (≤3 mm trace length). Measured eye height remains >60% of unit interval, satisfying USB-IF compliance margins without requiring receiver equalization.
Is PESD5V0S1UJ compatible with lead-free reflow processes?
Yes - the SC-90 (SOD323F) package supports JEDEC J-STD-020D-compliant lead-free reflow with peak temperature up to 260 °C. Recommended solder profile includes 60–90 s above 217 °C and ramp rates ≤3 °C/s to prevent package cracking or delamination.
