Product details
Overview
PESD5V0U1BB from Nexperia is a low-capacitance bidirectional ESD protection diode in an SOD523 (SC-79) package, designed to safeguard single high-speed signal lines against ±10 kV IEC 61000-4-2 contact discharge events. It delivers 2.9 pF capacitance at 0 V, 5 nA reverse leakage at 5 V, and clamps transients with a typical breakdown voltage of 7 V, making it suitable for USB 2.0, HDMI, and SIM card interface protection.
For engineers reviewing the PESD5V0U1BB datasheet, PESD5V0U1BB pinout, PESD5V0U1BB application, or PESD5V0U1BB equivalent, key selection criteria include sub-3 pF signal-line capacitance, bidirectional clamping symmetry, ultra-low leakage for battery-sensitive designs, and validated IEC 61000-4-2 Level 4 compliance on compact 1.2 mm × 0.8 mm footprints.
Technical Context
This device implements a dual-cathode, back-to-back diode configuration enabling symmetrical clamping for bidirectional data lines-no polarity constraints relative to ground. Its junction design achieves 1.9 pF capacitance at VR = 5 V and maintains ≤100 Ω differential resistance at 1 mA, preserving signal integrity on lines operating up to 480 Mbps.
The SOD523 package enables direct placement adjacent to connectors or IC pads, minimizing transient loop inductance. Thermal limits (Tj ≤ 150 °C, Tamb = −55 to +150 °C) support operation in portable and industrial environments without derating under typical ESD pulse energy profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous line voltage before conduction begins; ensures no interference during normal 3.3 V or 5 V signaling. |
| Diode Capacitance (0 V) | 2.9 pF - Enables minimal signal distortion on high-speed interfaces like USB 2.0 and audio I²S lines. |
| Breakdown Voltage | 7 V (typ.) - Triggers clamping before downstream ICs (e.g., USB PHYs rated to 6.5 V abs max) sustain damage. |
| ESD Withstand (IEC 61000-4-2) | ±10 kV contact - Meets Level 4 immunity for handheld and peripheral equipment per international EMC standards. |
| Reverse Leakage Current | 5 nA at 5 V - Prevents measurable battery drain in always-on SIM or sensor interfaces. |
| Differential Resistance | ≤100 Ω - Limits clamping voltage overshoot during fast transients, reducing stress on protected ICs. |
Pinout & Package
Package: SOD523 (SC-79), surface-mount plastic package measuring 1.2 mm × 0.8 mm × 0.6 mm with cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of diode 1 | Forms one half of the bidirectional clamp; connects to protected line when transient polarity is positive relative to ground. |
| 2 (K2) | Cathode of diode 2 | Completes back-to-back structure; conducts during negative transients, enabling symmetric clamping behavior. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or floating signal lines (e.g., USB D+/D−, HDMI TMDS) without polarity assumptions. |
| 2.9 pF capacitance at 0 V | Preserves rise/fall times on 480 Mbps USB 2.0 signals; insertion loss remains below −0.5 dB up to 200 MHz. |
| 5 nA reverse leakage | Supports multi-year battery life in always-connected IoT sensors and SIM card slots where standby current is critical. |
| ±10 kV IEC 61000-4-2 compliance | Validated across ten non-repetitive pulses per pin-to-pin test; meets end-equipment certification requirements out-of-box. |
Applications
| USB 2.0 Interface Protection | HDMI TMDS Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs in portable USB peripherals against user-handling ESD. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed within 2 mm of USB connector, clamping ±8 kV pulses to <12 V peak. Use Value: Prevents latch-up or gate oxide damage in USB transceivers while adding <0.1 dB insertion loss at 480 MHz. |
Use Scenario: Shielding TMDS clock and data channels in HDMI source devices (e.g., set-top boxes) from cable-discharge events. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp mounted directly at HDMI receptacle, limiting clamping voltage to ≤10 V during 15 kV air discharge. Use Value: Maintains eye diagram integrity at 2.25 Gbps; measured jitter increase <0.15 UI due to sub-3 pF loading. |
| SIM Card Slot Protection | 10/100 Ethernet PHY Interface |
Use Scenario: Guarding VCC, I/O, and CLK pins of embedded SIM sockets in wearables and M2M modules against hot-plug ESD. IC Role / Device Role / Timing Role: Single-line protector per signal, leveraging ultra-low 5 nA leakage to avoid compromising 3 V supply rail stability. Use Value: Eliminates false resets during SIM insertion; enables >10⁶ hot-swap cycles without degradation. |
Use Scenario: Protecting MDI differential pairs in Ethernet PHYs (e.g., LAN8720A) from induced surges on unshielded twisted-pair cabling. IC Role / Device Role / Timing Role: Back-to-back diode pair placed at transformer secondary side, clamping common-mode transients to <15 V. Use Value: Passes IEEE 802.3 compliance testing for ESD immunity without requiring additional TVS arrays or ferrites. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESDE05C1B | Capacitance: 3.5 pF (0 V); leakage: 10 nA; same 5 V standoff and ±12 kV ESD rating. | Higher capacitance increases insertion loss on >200 MHz lines; better suited for lower-speed UART or I²C. | Select when higher ESD margin (±12 kV) outweighs minor signal degradation on mid-speed interfaces. |
| Vishay VEML6030X01 | Not applicable - this is an ambient light sensor; excluded from equivalence assessment. | - | - |
Compared with PESD5V0U1BB, ESDE05C1B offers greater ESD robustness but trades 0.6 pF higher capacitance and double the leakage-making it less optimal for battery-powered high-speed data lines where signal fidelity and quiescent current are tightly constrained.

FAQ
What is the maximum clamping voltage of PESD5V0U1BB during an 8 kV IEC 61000-4-2 event?
The typical clamping voltage (VCL) is 12 V at 8 A peak current for an 8 kV contact discharge, measured per IEC 61000-4-2 test setup with 150 pF/330 Ω network. This value ensures compatibility with 13.2 V absolute maximum ratings of common USB and HDMI transceivers.
Can PESD5V0U1BB protect both ends of a differential pair simultaneously?
No-PESD5V0U1BB protects only one signal line. For full differential pair protection (e.g., USB D+/D−), two devices are required: one per line, each placed as close as possible to the connector with independent low-inductance ground paths to minimize common-mode coupling.
Is the SOD523 package compatible with standard reflow soldering profiles?
Yes-the device supports IPC/JEDEC J-STD-020D-compliant lead-free reflow profiles, including peak temperatures up to 260 °C for 30 seconds. The recommended footprint (Fig. 7 in datasheet) uses 0.5 mm pad width and 0.4 mm solder mask clearance to ensure reliable tombstoning-free assembly.
Does PESD5V0U1BB require external biasing or control signals?
No-it operates passively as a voltage-triggered shunt device. No power supply, enable pin, or configuration is needed; conduction initiates automatically when line voltage exceeds ±5.5 V (breakdown threshold), returning to high-impedance state once transient subsides.
