Product details
Overview
PESD5V0U1UB from Nexperia is a unidirectional electrostatic discharge (ESD) protection diode in SC-79 (SOD523) package, designed to safeguard single high-speed signal lines against ESD transients up to ±9 kV per IEC 61000-4-2 level 4. It delivers ultra-low 2 pF capacitance at 0 V, 1 nA reverse leakage at 5 V, and clamps transients with 5.8 V breakdown voltage at 5 mA.
For engineers reviewing the PESD5V0U1UB datasheet, PESD5V0U1UB pinout, PESD5V0U1UB application, or PESD5V0U1UB equivalent, this device is selected for USB 2.0, Gigabit Ethernet, SIM card interfaces, and other high-speed data paths where minimal signal distortion and robust transient immunity are required.
Technical Context
The PESD5V0U1UB implements a single unidirectional silicon diode structure optimized for low-capacitance transient suppression. Its clamping behavior is defined by a 5.8–8.8 V breakdown range at 5 mA and differential resistance under 100 Ω, enabling fast response to ESD pulses while maintaining signal integrity on lines operating up to 1 Gbit/s.
It operates within −55 °C to +150 °C ambient temperature and supports IEC 61000-4-2 contact discharge (±9 kV) and MIL-STD-883 HBM (±10 kV). The cathode-marked SC-79 package places the anode (pin 2) and cathode (pin 1) on a 1.2 mm × 0.8 mm footprint with 0.6 mm height.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous DC voltage the line can sustain without triggering conduction. |
| Diode Capacitance | 2 pF at 0 V - Enables use on USB 2.0 and 1000BASE-T Ethernet without signal integrity degradation. |
| Breakdown Voltage | 6.8 V typical at 5 mA - Ensures reliable turn-on before downstream ICs exceed absolute maximum ratings. |
| Reverse Leakage Current | 1 nA at 5 V - Prevents measurable DC loading on sensitive analog or low-power digital inputs. |
| ESD Withstand Level | ±9 kV IEC 61000-4-2 contact - Meets industrial and consumer end-equipment immunity requirements. |
| Differential Resistance | <100 Ω - Limits clamped voltage during high-current ESD events to protect interface ICs. |
Pinout & Package
Package: SC-79 (SOD523), plastic surface-mounted, 2-terminal, 1.2 mm × 0.8 mm × 0.6 mm body. Cathode identified by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode | Connected to system ground or reference plane; carries transient current during negative ESD events. |
| 2 (A) | Anode | Connected to protected signal line; conducts during positive ESD transients when voltage exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional configuration | Protects lines with fixed polarity (e.g., USB D+ referenced to GND), avoiding forward conduction during normal operation. |
| Ultra-low 2 pF capacitance | Maintains impedance matching and rise-time fidelity on 480 Mbps USB 2.0 and 1.25 Gbps Ethernet signals. |
| 1 nA reverse leakage | Eliminates measurable current draw on battery-powered SIM card interfaces and audio codec lines. |
| IEC 61000-4-2 level 4 compliance | Validated for ±9 kV contact discharge-meets EN 61000-6-2 and IEC 61000-6-4 system-level ESD requirements. |
Applications
| USB 2.0 Interface Protection | Gigabit Ethernet PHY Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of a USB 2.0 host controller against user-handling ESD events. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between signal line and ground, activated only during overvoltage transients. Use Value: 2 pF capacitance avoids eye diagram closure; 6.8 V breakdown ensures clamping occurs before USB transceiver's 6.5 V abs max rating is exceeded. |
Use Scenario: Shielding MDI differential pairs in 1000BASE-T Ethernet PHYs from connector-induced ESD. IC Role / Device Role / Timing Role: Single-line unidirectional protector applied per signal trace, grounded at local chassis point. Use Value: Sub-100 Ω dynamic resistance limits clamped voltage to <12 V during 8 kV IEC pulse, preserving PHY latch-up immunity. |
| SIM Card Slot Protection | Mobile Audio Data Line Protection |
Use Scenario: Safeguarding SIM VCC, I/O, and CLK lines in smartphones against hot-plug and handling ESD. IC Role / Device Role / Timing Role: Ground-referenced unidirectional clamp on each active signal, placed adjacent to SIM connector. Use Value: 1 nA leakage prevents battery drain; 5 V standoff matches SIM supply rail, enabling direct placement without level-shifting. |
Use Scenario: Protecting I²S or PCM data lines between baseband processor and audio codec in portable devices. IC Role / Device Role / Timing Role: Signal-line ESD suppressor with cathode tied to clean analog ground, minimizing noise injection. Use Value: 2 pF capacitance preserves 100 MHz+ signal bandwidth; low leakage avoids DC offset on high-impedance audio inputs. |
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 3.5 pF capacitance; bidirectional configuration; 12 kV ESD rating. | Requires redesign for bidirectional signal lines; less suitable for strictly unidirectional rails like SIM VCC. | Select when higher ESD margin is prioritized over signal integrity on sub-500 Mbps links. |
| Vishay VEML5010-001 | 1.5 pF capacitance; 5.5 V standoff; 10 kV ESD rating; SC-79 package. | Lower standoff voltage may trigger prematurely on 5 V-tolerant interfaces; tighter tolerance on Cd. | Prefer for ultra-high-speed links where sub-1.6 pF is critical, accepting reduced voltage headroom. |
Compared with NUP4105MR6T1G and VEML5010-001, the PESD5V0U1UB offers optimal balance of 5 V standoff, 2 pF capacitance, and 1 nA leakage-making it the default choice for USB 2.0, SIM, and 1 GbE applications where polarity is fixed and signal fidelity is non-negotiable.

FAQ
Is PESD5V0U1UB suitable for bidirectional signal lines like USB D+/D− differential pairs?
No-PESD5V0U1UB is unidirectional and must be used per line with correct polarity: anode to signal, cathode to ground. For true bidirectional protection (e.g., both D+ and D−), two devices are required-one per line-or a dedicated bidirectional array such as PESD5V0X1B.
What is the maximum recommended PCB trace length between PESD5V0U1UB and the protected connector?
Nexperia recommends placing the device within 2 mm of the I/O connector. Longer traces increase inductance, degrading clamping performance-especially for fast-rising ESD pulses-and may allow voltage overshoot exceeding downstream IC limits.
Does PESD5V0U1UB require a dedicated ground plane connection, or can it share a noisy digital ground?
A low-inductance, dedicated ground path to a clean system ground plane is mandatory. Sharing ground with switching regulators or high-speed digital returns introduces noise coupling and raises clamping voltage due to ground bounce during ESD events.
Can PESD5V0U1UB be used to protect a 3.3 V I/O rail without risk of premature conduction?
Yes-the 5 V reverse standoff voltage provides 1.7 V margin above 3.3 V nominal operation, and its 1 nA leakage at 5 V ensures negligible current draw. Breakdown begins at 5.8 V, well above normal operating swing.
