Product details
Overview
PESD5V0X1UB from Nexperia is a unidirectional ESD protection diode in SOD523 (SC-79) package, designed to protect single high-speed signal lines with 0.95 pF capacitance, 5.5 V reverse standoff voltage, and 8 V clamping voltage at 1.5 A surge current. It is AEC-Q101 qualified and used in USB, HDMI, and Ethernet data line protection.
For engineers reviewing the PESD5V0X1UB datasheet, PESD5V0X1UB pinout, PESD5V0X1UB application, or PESD5V0X1UB equivalent, key selection criteria include ultra-low capacitance for signal integrity, low clamping voltage for IC-level transient suppression, AEC-Q101 qualification for automotive interfaces, and SOD523 footprint compatibility with space-constrained PCB layouts.
Technical Context
This unidirectional TVS diode operates as a clamping device triggered by ESD transients exceeding its 5.8 V breakdown voltage. Its dynamic resistance of 0.25 Ω ensures rapid voltage limiting during 8/20 µs surge events up to 1.5 A.
The device exhibits negligible signal distortion on protected lines due to sub-1 pF capacitance at 1 MHz and 0 V bias, and maintains leakage below 1 nA at 5 V reverse bias-critical for battery-powered high-impedance interfaces like SIM card slots and I²C buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5.5 V - Maximum continuous operating voltage before leakage rises significantly; defines safe DC bias margin for protected signal lines. |
| Diode Capacitance | 0.95 pF (typ.) at 1 MHz, 0 V - Enables minimal signal attenuation and phase shift on >1 Gbps interfaces such as HDMI 1.4 and USB 2.0. |
| Clamping Voltage | 8 V at 1.5 A (8/20 µs) - Limits transient voltage seen by downstream ICs to within safe absolute maximum ratings. |
| ESD Withstand | ±8 kV contact discharge per IEC 61000-4-2 Level 4 - Meets industrial and automotive end-equipment immunity requirements. |
| Surge Current Rating | 1.5 A peak (8/20 µs) per IEC 61000-4-5 - Handles induced lightning surges and system-level coupling transients. |
| Leakage Current | 1 nA (typ.) at 5 V - Prevents measurable loading on high-impedance analog or logic inputs, preserving battery life in portable devices. |
| Breakdown Voltage | 5.8–7.5 V at 10 mA - Ensures reliable turn-on before damage threshold of typical 3.3 V or 5 V interface ICs. |
Pinout & Package
SOD523 (SC-79) surface-mount plastic package: 2-terminal, 1.2 mm × 0.8 mm × 0.6 mm body, cathode marked with bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to ground or low-impedance return path; clamping occurs when transient drives this terminal positive relative to anode. |
| 2 (A) | Anode | Connected to signal line under protection; conducts transient current to cathode during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.95 pF enables use on 10/100/1000 Mbit/s Ethernet and HDMI 1.4 without signal eye degradation. |
| Low clamping voltage | 8 V at 1.5 A ensures protected ICs remain within their 10 V absolute maximum rating during surge events. |
| AEC-Q101 qualification | Validated for automotive environments including temperature cycling, humidity, and mechanical shock per discrete semiconductor stress test standard. |
| Sub-nA leakage | 1 nA reverse current preserves signal integrity and battery runtime in always-on SIM card and audio codec interfaces. |
| Single-line protection | Dedicated two-pin configuration simplifies layout and eliminates cross-talk risk compared to multi-channel arrays. |
Applications
| USB 2.0 Data Lines | HDMI 1.4 TMDS Channels |
|---|---|
Use Scenario: Protection of D+ and D− differential pairs in portable USB peripherals and host controllers. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between each data line and ground, activated only during positive transients. Use Value: 0.95 pF capacitance prevents rise-time degradation and maintains USB 2.0 eye diagram compliance at 480 Mbps. |
Use Scenario: ESD protection of TMDS clock and data channels in flat-panel displays and set-top boxes. IC Role / Device Role / Timing Role: Ground-referenced transient suppressor on each TMDS line, leveraging low dynamic resistance for fast response. Use Value: 8 V clamping voltage keeps TMDS receivers (typically rated to 10 V) within safe operating limits during ±8 kV contact discharge. |
| SIM Card Interface | Automotive Infotainment Serial Links |
Use Scenario: Protection of VCC, I/O, CLK, and RST pins on subscriber identity module sockets in smartphones and tablets. IC Role / Device Role / Timing Role: Single-line ESD clamp per signal, selected for ultra-low leakage to avoid disrupting low-power card detection logic. Use Value: 1 nA reverse leakage prevents false card-insertion detection and extends standby battery life beyond 72 hours. |
Use Scenario: Signal line protection on LIN, CAN FD, or MOST physical layers in head units and telematics control units. IC Role / Device Role / Timing Role: Unidirectional transient suppressor on bidirectional bus lines where polarity is fixed relative to chassis ground. Use Value: AEC-Q101 qualification ensures reliability across -40 °C to +125 °C ambient, meeting automotive grade-2 requirements. |
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 ESD5Z5.0T1G | Higher capacitance (1.3 pF), higher clamping voltage (12 V at 1 A), same SOD-523 package. | Less suitable for >480 Mbps interfaces due to increased signal loading; better for lower-speed UART or I²C. | Select when cost sensitivity outweighs signal integrity needs and clamping voltage margin is sufficient. |
| Vishay ESDE5Z5.0 | Lower ESD rating (±6 kV), identical 0.95 pF capacitance, same AEC-Q101 qualification. | Not approved for full IEC 61000-4-2 Level 4 systems requiring ±8 kV robustness. | Choose only if system-level testing confirms ±6 kV immunity suffices and supply chain constraints require Vishay sourcing. |
Compared with ESD5Z5.0T1G and ESDE5Z5.0, PESD5V0X1UB delivers superior high-speed interface compatibility via lowest capacitance and tightest clamping, while maintaining automotive-grade reliability and full Level 4 ESD compliance-making it optimal for next-generation portable and infotainment designs.

FAQ
Is PESD5V0X1UB suitable for bidirectional signal lines?
No. PESD5V0X1UB is unidirectional and protects only positive-going transients on a line referenced to ground. For bidirectional protection (e.g., USB D+/D− differential pair), two devices are required-one per polarity-or a dedicated bidirectional variant like PESD5V0S1BA must be used.
What is the thermal derating behavior above 85 °C ambient?
Peak pulse current (IPPM) decreases linearly from 1.5 A at 25 °C to 1.0 A at 125 °C per Nexperia's derating curve. Junction temperature must not exceed 150 °C; PCB copper area and thermal vias directly under the SOD523 pad are recommended for sustained surge conditions.
How does the 0.95 pF capacitance affect 1000BASE-T Ethernet signals?
At 100 MHz (upper frequency of 1000BASE-T), 0.95 pF introduces <0.02 dB insertion loss and <0.1° phase shift-well within IEEE 802.3ab compliance margins. Layout best practices (short traces, ground stitching) ensure no measurable impact on return loss or NEXT/FEXT performance.
Can PESD5V0X1UB replace older PESD5V0R1B devices in existing designs?
Yes, with verification. Both share SOD523 package and unidirectional topology, but PESD5V0X1UB offers lower clamping (8 V vs. 10 V) and tighter capacitance (0.95 pF vs. 1.0 pF). Layout and system-level ESD testing should confirm improved transient suppression without signal integrity trade-offs.
