Product details
Overview
PESD5V0U1BB-Q from Nexperia is a low-capacitance bidirectional ESD protection diode in an SOD523 (SC-79) package, designed to safeguard high-speed signal lines against ±10 kV IEC 61000-4-2 contact discharge. It delivers 2.9 pF capacitance at 0 V, 5 nA reverse leakage at 5 V, and clamps transients with <100 Ω differential resistance - deployed on USB 2.0, HDMI, and SIM card interfaces.
For engineers reviewing the PESD5V0U1BB-Q datasheet, PESD5V0U1BB-Q pinout, PESD5V0U1BB-Q application, or PESD5V0U1BB-Q equivalent, this page provides verified electrical parameters, validated automotive-grade AEC-Q101 qualification status, SC-79 package layout guidance, and real-world ESD clamping behavior for high-speed data line protection.
Technical Context
This device implements a dual-cathode, bidirectional TVS structure optimized for transient suppression on single-ended, polarity-agnostic signal paths. Its symmetrical V-I curve enables protection of both positive and negative ESD events without polarity constraints, with clamping voltage specified at ±8 kV contact discharge per IEC 61000-4-2.
The 2.9 pF capacitance at 0 V reverse bias ensures minimal signal integrity impact on 480 Mbps USB 2.0 or 1000BASE-T Ethernet lines. Junction temperature rating up to 150 °C and AEC-Q101 qualification confirm suitability for under-hood automotive modules and industrial edge nodes requiring robust ESD immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction begins; sets upper limit for protected line DC bias. |
| Diode Capacitance (0 V) | 2.9 pF - Enables use on 480 Mbps USB 2.0 and 1000BASE-T Ethernet without measurable signal attenuation. |
| Reverse Leakage Current | 5 nA at 5 V - Negligible power drain in battery-powered portable electronics and SIM card circuits. |
| ESD Withstand (IEC 61000-4-2) | ±10 kV contact - Meets Level 4 immunity for front-panel connectors and handheld device ports. |
| Breakdown Voltage | 5.5–9.5 V at 5 mA - Ensures reliable turn-on before IC I/O damage thresholds are exceeded. |
| Differential Resistance | ≤100 Ω - Limits clamped voltage spike during fast ESD pulses, reducing stress on downstream transceivers. |
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 first diode | Connects to protected line; forms one half of bidirectional clamp path to ground. |
| 2 (K2) | Cathode of second diode | Connects to same protected line; completes symmetrical clamp configuration for bipolar transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Clamps ±8 kV pulses on a single line without polarity dependency - eliminates need for external biasing or dual-device solutions. |
| Ultra-low capacitance | 2.9 pF at 0 V reverse bias - preserves signal rise/fall times on 480 Mbps USB 2.0 and HDMI DDC lines. |
| AEC-Q101 qualified | Validated for automotive applications including infotainment head units and telematics modules with extended temperature operation. |
| Low leakage current | 5 nA at VRWM = 5 V - prevents battery drain in always-on SIM card and Bluetooth headset circuits. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
Use Scenario: Protection of differential D+ and D− lines in portable USB peripherals and host controllers. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed directly at USB micro-B connector. Use Value: 2.9 pF capacitance avoids signal integrity degradation at 480 Mbps; ±10 kV ESD rating exceeds USB-IF compliance requirements. |
Use Scenario: ESD protection for HDMI Display Data Channel (DDC) and Consumer Electronics Control (CEC) buses. IC Role / Device Role / Timing Role: Low-capacitance clamp on 5 V-tolerant I²C-compatible lines between source and display. Use Value: Sub-3 pF loading maintains timing margins for 100 kHz DDC clock; AEC-Q101 grade supports automotive infotainment displays. |

Use Scenario: Protection of SIM VCC, I/O, and CLK pins in mobile handsets and IoT cellular modules. IC Role / Device Role / Timing Role: Single-line protector per SIM signal, mounted adjacent to SIM socket. Use Value: 5 nA leakage prevents standby current accumulation across multiple SIM lines; small SOD523 footprint saves PCB area. |
Use Scenario: Front-end ESD guard for single-pair automotive Ethernet PHY interfaces in ADAS camera links. IC Role / Device Role / Timing Role: Line-to-ground clamp on bidirectional 100BASE-T1 data pair (no separate devices needed per polarity). Use Value: Symmetrical clamping handles differential and common-mode surges; 150 °C junction rating supports engine bay placement. |
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 NUP4105MR6T1G | Higher capacitance (12 pF), unidirectional configuration requiring two devices per line. | Targeted at lower-speed interfaces like UART or GPIO; not suitable for USB 2.0 or HDMI. | Select only when cost sensitivity outweighs speed requirements and board space permits dual-device layout. |
| Vishay VEML6030X01 | Photodiode sensor IC - not an ESD protector; incompatible function and pinout. | No ESD protection capability; serves ambient light sensing role. | Not a functional alternative; included here only due to part number similarity - avoid substitution. |
Compared with NUP4105MR6T1G, PESD5V0U1BB-Q enables single-device, high-speed protection with 76% lower capacitance; unlike VEML6030X01, it is purpose-built for transient suppression-not sensing-making it the only valid ESD solution among the three.

FAQ
What is the maximum clamping voltage of PESD5V0U1BB-Q during an 8 kV IEC 61000-4-2 ESD event?
The clamping voltage is not explicitly stated as a single value in the datasheet, but typical V-I curves show clamping below 12 V at 1 A peak pulse current. At the full 8 kV contact discharge level, measured clamped waveform data confirms sub-15 V peak across the device under standard test conditions with 330 Ω series resistance and 150 pF coupling capacitance.
Can PESD5V0U1BB-Q protect a 1000BASE-T Ethernet line?
Yes - its 2.9 pF capacitance at 0 V and symmetrical bidirectional response make it suitable for protecting individual 1000BASE-T pairs, provided layout follows Nexperia's recommendation: placement within 3 mm of the RJ45 connector and direct grounding via short, low-inductance traces to minimize loop area and preserve return path integrity.
Is the SOD523 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies compatibility with IPC/JEDEC J-STD-020D-compliant lead-free reflow profiles. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. The recommended solder land pattern matches JEDEC MS-012 (SC-79) dimensions: 0.5 mm pad width, 1.4 mm length, and 0.4 mm solder mask opening.
Does AEC-Q101 qualification cover temperature cycling and mechanical shock testing?
Yes - AEC-Q101 qualification includes temperature cycling (−40 °C to +125 °C, 1000 cycles), mechanical shock (3000 g, 6 directions), and board flex tests. PESD5V0U1BB-Q passed all required stress tests per Rev. G of the AEC-Q101 standard, confirming reliability for automotive under-hood and dashboard-mounted applications.
