Product details
Overview
PESD15VS1ULD from Nexperia is a unidirectional ESD protection diode in SOD882D package, designed to safeguard one signal line against electrostatic discharge up to 30 kV (IEC 61000-4-2 Level 4) and surge pulses (5 A, 8/20 μs). It features 15 V reverse standoff voltage, 23 V clamping voltage at 1 A, 32 pF typical capacitance, and <1 nA leakage current - enabling high-speed data line protection in space-constrained portable electronics.
For engineers reviewing the PESD15VS1ULD datasheet, PESD15VS1ULD pinout, PESD15VS1ULD application, or PESD15VS1ULD equivalent, this device is selected for ultra-low-capacitance, AEC-Q101-qualified transient suppression on single-ended I/O lines where board area and signal integrity are critical - especially in USB, audio, and automotive infotainment interfaces.
Technical Context
This unidirectional TVS diode operates as a clamping device: it remains high-impedance below 15 V VRWM, then rapidly transitions to low dynamic resistance (0.6 Ω) during transients to limit voltage across protected lines. Its 8/20 μs surge rating of 5 A and 150 W peak pulse power aligns with IEC 61000-4-5 requirements for system-level surge immunity.
The SOD882D package enables direct integration into high-density PCB layouts with visible, solderable side pads and 0.37 mm typical height. Its AEC-Q101 qualification confirms suitability for automotive environments, while sub-1 nA IRM ensures minimal loading on low-power sensor or audio signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - Maximum continuous reverse voltage before conduction; defines safe operating range for protected signal lines. |
| VCL @ IPP = 1 A | 23 V - Clamped voltage during 1 A ESD event; determines maximum stress imposed on downstream ICs. |
| Cd @ 1 MHz | 32 pF (typ) - Low capacitance minimizes signal distortion on high-speed lines like USB 2.0 or I²S audio. |
| IPP | 5 A - Peak surge current handling per IEC 61000-4-5 (8/20 μs), supporting robust system-level transient immunity. |
| IRM | <1 nA - Ultra-low leakage preserves battery life and avoids DC offset in precision analog or sensor circuits. |
| ESD Rating | ±30 kV contact (IEC 61000-4-2 Level 4) - Meets highest industrial and automotive ESD immunity requirements. |
| Package | SOD882D - 1.0 × 0.6 × 0.37 mm leadless SMD with solderable side pads; optimized for automated assembly and minimal PCB footprint. |
Pinout & Package
The PESD15VS1ULD is housed in a SOD882D leadless ultra-small surface-mount plastic package (1.0 × 0.6 × 0.37 mm), featuring visible and solderable side pads for reliable reflow attachment and optical inspection. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to ground or lower-potential reference; conducts during positive transients on anode side. |
| 2 | Anode | Connected to protected signal line; accepts ESD/surge energy and routes it to cathode (ground path). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 32 pF typical - Enables use on 480 Mbps USB 2.0, I²S, and other high-speed digital interfaces without signal degradation. |
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard - Validated for under-hood and infotainment applications requiring extended temperature and reliability compliance. |
| Low clamping voltage | 23 V at 1 A - Limits voltage overshoot to protect 3.3 V or 5 V logic ICs with tight absolute maximum ratings. |
| Solderable side pads | Visible copper terminations on package sides - Supports automated optical inspection (AOI) and improves solder joint reliability vs. bottom-only terminations. |
| Miniature footprint | 1.0 × 0.6 mm body - Saves >50% board area vs. SOD-323, critical for smartphones, wearables, and compact IoT modules. |
Applications
| USB 2.0 Data Lines | Automotive Infotainment I/O |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G | Lower VRWM (3.3 V); higher Cd (110 pF typ); same SOD-523 package. | Better suited for 3.3 V logic rails but unsuitable for 5 V or analog lines due to excessive capacitance. | Select only when protecting low-voltage digital I/O where capacitance tolerance >100 pF is acceptable. |
| TPD1E05U06DPYR | Lower VCL (9.5 V @ 1 A); higher Cd (12 pF typ); same 0402 footprint but different internal structure (dual-diode array). | Optimized for high-speed USB 3.0/PCIe; lacks AEC-Q101 qualification and 30 kV ESD rating. | Prefer for consumer-grade high-speed serial links; avoid in automotive or industrial surge-critical designs. |
Compared with ESD5Z3.3T5G and TPD1E05U06DPYR, the PESD15VS1ULD uniquely balances 15 V standoff, 32 pF capacitance, AEC-Q101 qualification, and 30 kV ESD rating - making it the only choice for automotive-grade, medium-voltage analog/digital signal protection in ultra-compact layouts.

FAQ
Is PESD15VS1ULD bidirectional or unidirectional?
The PESD15VS1ULD is strictly unidirectional: it conducts only when the anode is positive relative to the cathode. This configuration provides optimal clamping for signals referenced to ground, such as USB D+ or microphone bias lines, and avoids leakage during negative signal excursions.
What is the maximum operating temperature for continuous use?
The PESD15VS1ULD supports continuous operation from −55 °C to +150 °C ambient temperature, with junction temperature limited to 150 °C. Its AEC-Q101 qualification validates performance across the full automotive temperature range (−40 °C to +125 °C).
Can it be used on differential signal pairs like USB D+/D−?
Yes - two separate PESD15VS1ULD devices can protect D+ and D− individually. Each diode connects anode to its respective line and cathode to ground, preserving differential signaling integrity while providing independent 30 kV ESD protection per line.
Does the SOD882D package support standard reflow soldering profiles?
Yes - Nexperia specifies reflow soldering as the only recommended process. The SOD882D footprint is compatible with IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and standard lead-free reflow profiles, including peak temperatures up to 260 °C.
