Product details
Overview
PESD3V3X1BL from Nexperia is a bidirectional ESD protection diode in DFN1006-2 (SOD882) package, designed to safeguard high-speed signal lines against electrostatic discharge. It delivers 9 kV IEC 61000-4-2 contact ESD protection, ultra-low 1.3 pF capacitance at 1 MHz, 1 nA reverse leakage at 3 V, and AEC-Q101 qualification for automotive-grade reliability - deployed in USB interfaces and antenna protection circuits.
For engineers reviewing the PESD3V3X1BL datasheet, PESD3V3X1BL pinout, PESD3V3X1BL application, or PESD3V3X1BL equivalent, key selection criteria include clamping voltage under 8 kV stress, sub-2 pF capacitance for >1 Gbps data integrity, dual-cathode configuration for bidirectional line protection, and SOD882 footprint compatibility with high-density PCB layouts.
Technical Context
This device implements a symmetric dual-diode topology with cathodes on both terminals (Pin 1 = K1, Pin 2 = K2), enabling bidirectional transient suppression without polarity constraints. Its low 1.3 pF capacitance and 100 Ω differential resistance preserve signal integrity on high-speed lines such as USB 2.0 and 10/100/1000BASE-T Ethernet.
The 3.3 V reverse standoff voltage (VRWM) defines its operational window before conduction, while 5–7.8 V breakdown (VBR at 5 mA) and clamped response under IEC 61000-4-2 pulses ensure robust protection without false triggering during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V reverse standoff voltage - ensures no conduction during normal 3.3 V signal operation |
| VBR | 5–7.8 V breakdown at 5 mA - defines onset of clamping under overvoltage stress |
| Cd | 1.3 pF typical at 1 MHz, 0 V - enables minimal signal distortion on >1 Gbps data lines |
| IRM | 1 nA max reverse leakage at 3 V - prevents DC loading of sensitive analog or RF paths |
| ESD Rating | 9 kV contact per IEC 61000-4-2 Level 4 - meets industrial and automotive system-level ESD immunity requirements |
| Package | DFN1006-2 (SOD882), 1.0 × 0.6 × 0.48 mm - supports ultra-compact routing near connectors and antennas |
| AEC-Q101 | Qualified - validated for automotive applications including infotainment and telematics modules |
Pinout & Package
Package: DFN1006-2 (SOD882), leadless ultra-small surface-mount plastic package with 0.65 mm pitch, 1.0 mm × 0.6 mm body and 0.48 mm height. Cathode marking visible on top side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Forms one half of symmetrical clamp path; connects to protected line and ground via PCB layout |
| 2 | K2 (cathode of diode 2) | Completes bidirectional clamp structure; enables equal positive/negative transient suppression |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Single-device solution for ± transients on one signal line - eliminates need for discrete dual-diode arrays |
| Ultra-low capacitance | 1.3 pF typical - preserves edge rate and eye diagram integrity on USB 2.0 and Gigabit Ethernet |
| Low leakage current | 1 nA at VRWM - avoids signal offset or bias shift in precision analog front-ends and RF receivers |
| AEC-Q101 qualification | Validated for automotive temperature range (−55 °C to +150 °C) and mechanical stress - suitable for under-hood and dashboard modules |
| IEC 61000-4-2 Level 4 compliance | 9 kV contact discharge rating - satisfies EN 55032/55035 and ISO 10605 system-level immunity requirements |
Applications
| USB 2.0 Interface Protection | Automotive Antenna Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals and host controllers against user-handling ESD events. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at USB connector, clamping fast-rising ESD pulses before they reach PHY ICs. Use Value: 1.3 pF capacitance prevents signal degradation at 480 Mbps, maintaining full USB 2.0 compliance without retiming or equalization. |
Use Scenario: Shielding GPS/GNSS or cellular diversity antenna feed lines in automotive infotainment systems from cable-discharge events. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp mounted adjacent to SMA connector, shunting transients to chassis ground before entering LNA input. Use Value: AEC-Q101 qualification ensures stable performance across −40 °C to +105 °C ambient, critical for under-dash mounting locations. |
| High-Speed Ethernet PHY Protection | SIM Card Interface Protection |
Use Scenario: Safeguarding 10/100/1000BASE-T differential pairs in network switches and IoT gateways exposed to field service ESD. IC Role / Device Role / Timing Role: One PESD3V3X1BL per differential pair (e.g., TX+/TX−), placed before magnetics to limit coupled surge energy. Use Value: Sub-2 pF capacitance avoids skew between differential signals, preserving common-mode rejection and jitter margin at 1.25 Gbps. |
Use Scenario: Protecting SIM card VCC, I/O, and CLK lines in smartphones and M2M modules from insertion/removal ESD. IC Role / Device Role / Timing Role: Single-line protector on each SIM interface signal, leveraging bidirectional capability to handle both hot-swap and static events. Use Value: 1 nA leakage prevents battery drain in always-on standby mode, extending device runtime without compromising protection level. |
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 | Quad-channel array in SOT-563; 12 pF per channel; 12 kV ESD rating | Higher capacitance limits use to ≤100 Mbps interfaces; better suited for multi-line board-level protection | Select when protecting ≥2 lines simultaneously and signal speed < 100 Mbps |
| Vishay VEML3010-001 | Single-line device in SOD-323; 0.6 pF capacitance; 3.3 V VRWM; not AEC-Q101 qualified | Lacks automotive qualification; lower leakage (0.5 nA) but unverified for under-hood thermal cycling | Select for cost-sensitive consumer audio/video where AEC-Q101 is not required |
Compared with NUP4105MR6T1G and VEML3010-001, PESD3V3X1BL uniquely balances ultra-low capacitance (1.3 pF), automotive qualification, and single-line simplicity - making it optimal for space-constrained, high-speed, and automotive-grade designs where individual line control and thermal reliability are mandatory.

FAQ
What is the maximum clamping voltage of PESD3V3X1BL under IEC 61000-4-2 8 kV contact discharge?
The clamping voltage is not explicitly specified in the datasheet, but Figure 4 shows clamped waveforms at ±8 kV with peak voltage below 12 V across the device terminals. This aligns with typical performance of 3.3 V-rated bidirectional ESD diodes under standardized test conditions and confirms effective suppression without damaging downstream ICs.
Can PESD3V3X1BL be used on a 5 V signal line?
No - its 3.3 V reverse standoff voltage (VRWM) means conduction begins near 3.3 V, risking false triggering and increased leakage on 5 V lines. It is strictly intended for 3.3 V or lower nominal signal rails such as USB D+/D−, SIM I/O, or 3.3 V Ethernet PHY interfaces.
Is the DFN1006-2 package compatible with standard reflow profiles?
Yes - the device is qualified for JEDEC J-STD-020D reflow, with peak temperature up to 260 °C. Figure 7 provides the recommended solder paste stencil and land pattern, and thermal validation confirms reliable joint formation using standard Pb-free reflow profiles without voiding or tombstoning.
Does PESD3V3X1BL require external series impedance for optimal protection?
No external resistor is required for basic ESD protection, but layout best practices mandate placement within 2 mm of the protected connector and direct low-inductance grounding. Adding series impedance (e.g., 0–33 Ω) may improve high-frequency filtering but must be evaluated against signal rise-time degradation in >480 Mbps applications.
