Product details
Overview
PESD5V0L1ULD from Nexperia is a low-capacitance (25 pF typ.), unidirectional ESD protection diode rated for 5 V reverse standoff voltage, 12 V clamping at 3.5 A surge, and 26 kV IEC 61000-4-2 contact discharge - designed to protect single high-speed signal lines in portable electronics interfaces.
For engineers reviewing the PESD5V0L1ULD datasheet, PESD5V0L1ULD pinout, PESD5V0L1ULD application, or PESD5V0L1ULD equivalent, key selection criteria include ultra-low capacitance for signal integrity, SOD882D package compatibility with fine-pitch PCB layouts, clamping performance under IEC 61000-4-5 surge, and cathode-marked polarity alignment in unidirectional line protection.
Technical Context
This device operates as a unidirectional transient voltage suppressor, leveraging silicon PN junction behavior to clamp ESD events above its 6.8 V typical breakdown voltage while maintaining sub-100 nA leakage at 5 V. Its dynamic resistance of 0.7 Ω enables rapid energy dissipation during 8/20 µs surges.
The SOD882D (DFN1006D-2) package integrates solderable side pads for automated optical inspection and IPC-compliant reflow, with a 0.37 mm typical height enabling placement adjacent to high-density connectors without mechanical interference.
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 on protected line. |
| Diode Capacitance | 25 pF (typ.) at 1 MHz, 0 V - Enables use on USB 2.0, HDMI, or audio data lines without signal distortion or bandwidth loss. |
| Clamping Voltage | 12 V at 3.5 A (IEC 61000-4-5) - Limits transient overvoltage seen by downstream ICs during surge events. |
| ESD Withstand | 26 kV contact discharge (IEC 61000-4-2 Level 4) - Meets industrial and consumer immunity requirements without external circuitry. |
| Breakdown Voltage | 6.8 V (typ.) at 5 mA - Ensures reliable turn-on margin above 5 V operating rail while avoiding false triggering. |
| Peak Pulse Current | 3.5 A (8/20 µs) - Supports robust protection against lightning-induced surges in communication ports. |
Pinout & Package
Package: DFN1006D-2 (SOD882D), leadless ultra-small surface-mount plastic package; dimensions 1.0 × 0.6 × 0.4 mm, 0.65 mm pitch, visible and solderable side pads, cathode indicated by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to ground or lower-potential reference; current flows from anode to cathode during ESD clamping. |
| 2 | Anode (A) | Connected to protected signal line; polarity must match unidirectional signal path (e.g., positive-only or negative-only relative to GND). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 25 pF typ. - Preserves signal rise/fall times on high-speed interfaces up to 480 Mbps (USB 2.0). |
| Solderable side pads | Visible flank geometry - Enables automated optical inspection (AOI) and reliable reflow joint formation per IPC-A-610 Class 2/3. |
| Low clamping voltage | 12 V at 3.5 A - Keeps protected ICs within absolute maximum ratings during worst-case surge transients. |
| Compact footprint | 1.0 mm × 0.6 mm body - Fits within 1.4 mm × 0.8 mm PCB land pattern, minimizing board area in space-constrained portable designs. |
| High ESD rating | 26 kV contact discharge - Exceeds IEC 61000-4-2 Level 4, reducing need for secondary protection layers. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs in smartphone docking stations and OTG adapters. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between connector and USB transceiver, referenced to system ground. Use Value: 25 pF capacitance avoids signal integrity degradation at 480 Mbps, while 12 V clamping prevents PHY latch-up during cable insertion ESD events. |
Use Scenario: Safeguarding HPD (Hot-Plug Detect) signal in HDMI source devices like set-top boxes and media players. IC Role / Device Role / Timing Role: Single-line ESD suppressor connected between HPD pin and ground, with anode tied to HPD line. Use Value: Sub-100 nA leakage ensures stable DC logic level detection; 26 kV ESD rating covers repeated plug/unplug cycles without degradation. |
| Smartphone Audio Jacks | Industrial RS-485 Transceivers |
Use Scenario: Shielding microphone and headset detection lines in 3.5 mm TRRS jacks against user-hand ESD. IC Role / Device Role / Timing Role: Unidirectional protection element on biased analog sense lines, oriented to block positive transients only. Use Value: 0.37 mm package height allows placement directly behind jack PCB cutouts; low leakage avoids false detection in bias networks. |
Use Scenario: Front-end surge suppression on RS-485 A/B bus lines in factory automation gateways. IC Role / Device Role / Timing Role: Line-to-ground clamp on each differential conductor, configured with correct polarity for common-mode transient suppression. Use Value: 3.5 A peak pulse current handles IEC 61000-4-5 Level 3 surges; 0.7 Ω dynamic resistance minimizes voltage overshoot during fast-rising transients. |
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 capacitance (35 pF), dual-channel configuration, 12 V clamping at 3 A. | Requires shared ground return for two lines; less suitable for isolated single-line protection. | Select when protecting multiple adjacent lines with common ground and relaxed capacitance budget. |
| Vishay ESDE105B1R | Lower clamping voltage (9.5 V at 3.5 A), same 25 pF capacitance, but 5.5 V standoff voltage. | Marginally higher VRWM may limit use on strict 5 V rails with tolerance stack-up. | Prefer where tighter clamping is critical and system supply tolerances allow 5.5 V standoff. |
Compared with NUP4105MR6T1G and ESDE105B1R, PESD5V0L1ULD offers optimal balance of 5 V standoff compliance, 25 pF signal transparency, and 26 kV ESD robustness in a minimal 1.0 × 0.6 mm footprint - making it preferred for single-line, space-constrained, high-speed interface protection.

FAQ
What is the polarity configuration of PESD5V0L1ULD and how is it identified on the package?
The PESD5V0L1ULD is a unidirectional diode with anode (pin 2) and cathode (pin 1). The cathode is marked by a visible bar on the top surface of the SOD882D package, aligned with pin 1. This orientation requires the anode to connect to the protected signal line and the cathode to system ground for proper clamping of positive transients.
Can PESD5V0L1ULD be used on bidirectional signal lines such as USB D+ and D−?
No - PESD5V0L1ULD is strictly unidirectional and protects only one polarity of transient. For bidirectional lines like USB differential pairs, two devices are required per line (one anode-to-line/cathode-to-GND for positive transients, and a second cathode-to-line/anode-to-GND for negative transients), or a dedicated bidirectional variant must be selected.
What is the maximum ambient temperature at which PESD5V0L1ULD maintains full IEC 61000-4-2 26 kV rating?
The 26 kV ESD rating is specified at Tamb = 25 °C per IEC 61000-4-2 test conditions. While the device operates continuously from −55 °C to +150 °C ambient, ESD performance degrades above 85 °C due to increased junction leakage; full 26 kV compliance is guaranteed only within the 25 °C ±5 °C test environment defined in the standard.
How does the 0.7 Ω dynamic resistance impact system-level surge protection performance?
The 0.7 Ω dynamic resistance (measured via TLP at 10 A) directly determines voltage overshoot during fast transients: for a 3.5 A surge, it contributes ~2.5 V additional drop beyond the intrinsic clamping voltage. This low value ensures total clamped voltage stays near 12 V, keeping protected ICs well within their absolute maximum input voltage limits during IEC 61000-4-5 events.
