Product details
Overview
PESD18VF1BLYL from Nexperia is a bidirectional ultra-low-capacitance ESD protection diode in DFN1006-2 (SOD882) package, designed to protect single high-speed signal lines against ±10 kV IEC 61000-4-2 ESD events. It delivers 0.35 pF typical capacitance, 18 V reverse standoff voltage, and 17 V clamping voltage at 1 A, enabling use in NFC antenna and USB 2.0 data line protection.
For engineers reviewing the PESD18VF1BLYL datasheet, PESD18VF1BLYL pinout, PESD18VF1BLYL application, or PESD18VF1BLYL equivalent, key selection criteria include sub-0.4 pF capacitance stability across bias, snap-back clamping behavior for low-voltage rail compatibility, and validated 1 A surge current handling per IEC 61000-4-5.
Technical Context
This device implements a bidirectional snap-back clamping structure with negative dynamic resistance, enabling rapid transition into low-impedance conduction during ESD transients while maintaining <1 nA leakage at 18 V. Its symmetrical V-I characteristics support AC-coupled or bipolar signal lines without polarity constraints.
The DFN1006-2 footprint ensures minimal parasitic inductance and capacitance in PCB layout, critical for preserving signal integrity on >100 MHz interfaces. Clamping performance is characterized under both 8/20 µs surge and 100 ns TLP pulses, with dynamic resistance specified at 0.8 Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 18 V - Maximum continuous DC voltage the diode blocks without conduction, ensuring no interference with 18 V logic or analog rails. |
| Diode Capacitance | 0.35 pF (typ.) at 1 MHz, 0 V - Enables minimal signal distortion on high-speed lines up to 500 MHz (e.g., NFC, USB 2.0). |
| Clamping Voltage | 17 V at 1 A, 8/20 µs - Limits transient voltage seen by downstream ICs during IEC 61000-4-5 surges. |
| ESD Rating | ±10 kV contact / ±15 kV air per IEC 61000-4-2 - Meets Level 4 industrial immunity requirements. |
| Breakdown Voltage | 22 V (typ.) at 10 mA - Defines snap-back initiation threshold; ensures margin above 18 V VRWM. |
| Dynamic Resistance | 0.8 Ω - Low impedance during clamping reduces voltage overshoot and power dissipation during fast transients. |
Pinout & Package
DFN1006-2 (SOD882) plastic leadless package: 1.0 mm × 0.6 mm × 0.48 mm body, 0.65 mm pitch, two terminals, top-side marking bar indicating cathode orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Anode of first diode segment; connects to protected line when used in bidirectional configuration. |
| 2 | Cathode (Diode 2) | Anode of second diode segment; forms symmetrical clamping path with Pin 1 for AC signals. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.35 pF typ. - Preserves signal rise/fall times and impedance matching on GHz-range RF and digital lines. |
| Snap-back clamping | Negative dynamic resistance behavior - Reduces clamping voltage from breakdown level (22 V) to 17 V during ESD, protecting 18 V-rated ICs. |
| Bidirectional symmetry | Matched VBR and VCL for ± polarity - Eliminates need for polarity-aware placement on differential or AC-coupled lines. |
| Small-footprint SMD | DFN1006-2 (1.0 × 0.6 mm) - Minimizes PCB area and parasitic loop inductance for optimal ESD path to ground. |
Applications
| NFC Antenna Interface | USB 2.0 Data Lines |
|---|---|
Use Scenario: Protecting 13.56 MHz NFC antenna traces from ESD during user handling or connector insertion. IC Role / Device Role / Timing Role: Bidirectional transient voltage clamp placed between antenna coil and NFC controller RF pins. Use Value: 0.35 pF capacitance avoids detuning of antenna resonance; ±10 kV rating meets IEC 61000-4-2 Level 4 compliance. |
Use Scenario: Safeguarding D+ and D− lines in portable USB 2.0 peripherals against electrostatic discharge. IC Role / Device Role / Timing Role: Line-to-ground ESD suppressor mounted adjacent to USB connector, minimizing trace inductance.

Use Value: Symmetrical clamping ensures equal transient suppression on both polarities; 0.65 mm pitch enables dense routing on compact flex PCBs. |
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 ESDE0402MUTAG | 0.25 pF typ. capacitance, 12 V VRWM, ±15 kV ESD rating | Lower standoff voltage limits use on 15 V+ rails; tighter capacitance suits >1 GHz RF paths | Select when prioritizing lowest possible capacitance over voltage headroom |
| Vishay VEML6030X01 | 0.5 pF typ. capacitance, 24 V VRWM, ±8 kV ESD rating | Higher voltage rating but reduced ESD robustness; larger 0402 footprint increases parasitics | Choose for legacy 0402 layouts where 24 V rail compatibility is required |
Compared with PESD18VF1BLYL, ESDE0402MUTAG offers lower capacitance but sacrifices 6 V standoff margin, while VEML6030X01 trades ESD robustness and size for higher voltage tolerance-making PESD18VF1BLYL optimal for balanced 18 V, ±10 kV, sub-0.4 pF designs.

FAQ
What is the maximum continuous operating voltage for PESD18VF1BLYL?
The maximum continuous reverse operating voltage is 18 V (VRWM), verified per IEC 61000-4-2 test conditions at 25 °C ambient. Operation above this voltage risks premature conduction and increased leakage; it is not rated for sustained DC bias beyond 18 V.
Can PESD18VF1BLYL be used on differential signal pairs?
Yes-its symmetrical bidirectional structure allows direct placement across differential lines (e.g., D+/D−) or individually on each line referenced to ground. The matched VBR and VCL ensure balanced clamping without skew or common-mode disruption.
How does the snap-back behavior affect circuit design?
Snap-back reduces clamping voltage from ~22 V (breakdown) to 17 V during ESD events, but requires careful PCB layout: keep trace inductance low and ground path short to avoid oscillation or delayed triggering. Do not apply unlimited DC current after breakdown.
Is PESD18VF1BLYL qualified for automotive applications?
No-per Nexperia's revision history (v.3, April 2023), this part is non-automotive qualified. Automotive-grade alternatives (e.g., PESD18VF1BL-Q) are separately qualified to AEC-Q101 and documented on Nexperia's website.
