Product details
Overview
PESD5V0S1UAF 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, HDMI interfaces, and portable audio jacks.
For engineers reviewing the PESD5V0S1UAF datasheet, PESD5V0S1UAF pinout, PESD5V0S1UAF application, or PESD5V0S1UAF equivalent, key selection criteria include unidirectional polarity handling, low 0.3 µA leakage at 5 V, AEC-Q101 qualification for automotive-grade reliability, and compact 1.7 mm × 1.25 mm footprint for high-density PCB layouts.
Technical Context
This device operates as a single-line transient voltage suppressor with avalanche breakdown at 6.8 V (typical), enabling fast clamping response to sub-nanosecond ESD events. Its unidirectional architecture allows integration on positive-polarity signal paths without reverse-bias conduction risk.
Thermal resistance from junction to solder point is 250 K/W under standard FR4 mounting, supporting sustained pulse handling up to 890 W peak power (8/20 µs waveform). The 345 K/W junction-to-ambient rating reflects its reliance on PCB copper area for thermal dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - maximum continuous DC voltage the diode blocks without leakage exceeding 0.3 µA |
| Clamping Voltage | 19 V at 47 A - limits transient voltage seen by protected IC during IEC 61000-4-5 surge |
| ESD Rating | ±30 kV contact per IEC 61000-4-2 - withstands worst-case human-body ESD events without degradation |
| Diode Capacitance | 480 pF at 1 MHz - low enough for USB 2.0 and audio line protection without signal integrity loss |
| Peak Pulse Power | 890 W - handles high-energy transients while maintaining <10 ns response time |
| Leakage Current | 0.3 µA at 5 V - ensures minimal loading on low-power sensor or audio bias networks |
| Breakdown Voltage | 6.8 V (typ) at 5 mA - defines precise turn-on threshold for controlled clamping onset |
Pinout & Package
SOD323 surface-mount plastic package: 2-pin, 1.3 mm pitch, 1.7 mm × 1.25 mm × 0.95 mm body; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to ground or low-impedance return path; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to signal line requiring protection; conducts only when line voltage exceeds VRWM + VBR |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD Protection | Enables use on single-polarity signal lines (e.g., USB D+, HDMI TMDS+) without reverse conduction risk |
| AEC-Q101 Qualification | Validated for automotive infotainment and ADAS interface protection across -55 °C to 150 °C ambient |
| Low Clamping Ratio | VCL/VBR = 19 V / 6.8 V ≈ 2.79 - tight voltage control minimizes stress on downstream logic inputs |
| Small-Footprint SOD323 | 1.7 mm × 1.25 mm area supports routing of high-speed differential pairs with minimal stub length |
| IEC 61000-4-5 Compliance | Rated for 47 A surge current (8/20 µs) - meets industrial Ethernet and CAN FD port protection requirements |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals against electrostatic discharge during cable insertion. IC Role / Device Role: Unidirectional TVS diode placed between connector and USB transceiver IC. Use Value: 480 pF capacitance avoids signal rise-time degradation; 19 V clamping prevents transceiver latch-up during ±8 kV ESD contact events. |

Use Scenario: Protecting analog front-end inputs of patient-monitoring ECG or SpO₂ modules from clinical environment ESD. IC Role / Device Role: Low-leakage transient suppressor on sensor signal path before instrumentation amplifier. Use Value: 0.3 µA IRM prevents DC offset shift in high-gain biopotential amplifiers; 19 V clamping avoids ADC saturation during defibrillator leakage pulses. |
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 VRWM; 25 V clamping at 24 A; 30 pF capacitance | Better suited for 12 V industrial I/O; too high VRWM for 5 V USB lines | Select only if protecting >10 V signal rails where lower capacitance justifies reduced ESD margin |
| Vishay ESDE105B1R | 5 V VRWM; 15 V clamping at 40 A; 120 pF capacitance; non-AEC-Q101 | Limited to consumer electronics; insufficient thermal robustness for automotive under-hood use | Prefer for cost-sensitive portable devices where AEC-Q101 is not mandated and lower capacitance is critical |
Compared with NUP4105MR6T1G and ESDE105B1R, PESD5V0S1UAF uniquely balances 5 V compatibility, 30 kV ESD rating, AEC-Q101 qualification, and SOD323 size - making it optimal for space-constrained automotive and industrial USB/HDMI interfaces requiring guaranteed reliability.

FAQ
Is PESD5V0S1UAF suitable for bidirectional signal lines like RS-485?
No. PESD5V0S1UAF is unidirectional and conducts only when anode voltage exceeds cathode by ≥6.8 V. For bidirectional lines, a symmetric dual-diode array such as PESD5V0X1B or bidirectional TVS like PESD5V0S1BA is required to clamp both positive and negative transients.
What is the maximum recommended PCB trace length between PESD5V0S1UAF and the protected connector?
Trace length should be ≤3 mm from connector pad to diode anode, with direct ground connection from cathode to solid ground plane via shortest possible path. Longer traces increase inductance, degrading clamping performance during sub-nanosecond ESD events.
Does PESD5V0S1UAF require derating at elevated ambient temperatures?
Yes. Peak pulse power drops to 50% of 890 W at 125 °C junction temperature (Fig. 4). Designers must ensure thermal resistance from junction to ambient remains ≤250 K/W using adequate copper pour and avoid placement near heat sources to maintain full surge rating.
Can PESD5V0S1UAF replace older PESD5V0S1BA in existing designs?
No. PESD5V0S1BA is bidirectional (VRWM = ±5 V); PESD5V0S1UAF is unidirectional (VRWM = 5 V, cathode grounded). Substitution would leave negative transients unprotected and may cause forward conduction during negative signal excursions.
