Product details
Overview
PESD18VF1BBL-Q from Nexperia is a bidirectional ESD protection diode in DFN1006-2 (SOD882) package, designed to safeguard single high-speed signal lines against ±10 kV contact/±15 kV air discharge per IEC 61000-4-2. It delivers ultra-low 0.31 pF capacitance, 18 V reverse standoff voltage, and AEC-Q101 qualification for automotive NFC antenna and USB 2.0 data line protection.
For engineers reviewing the PESD18VF1BBL-Q datasheet, PESD18VF1BBL-Q pinout, PESD18VF1BBL-Q application, or PESD18VF1BBL-Q equivalent, key selection criteria include clamping voltage under 20 V at 16 A TLP, dynamic resistance ≤0.8 Ω, and sub-1 mm² footprint compatibility with space-constrained RF front-end layouts.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance, enabling rapid transition into low-impedance conduction during ESD events to suppress transient voltages below 20 V. Its bidirectional symmetry supports AC-coupled or dual-polarity signal paths without polarity constraints.
Designed for placement directly at I/O connectors, it operates within −55 °C to +150 °C ambient range and maintains <30 nA reverse leakage at 18 V VRWM. The DFN1006-2 package uses solderable side-wettable flanks for automated optical inspection of solder joints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 18 V - Maximum continuous reverse operating voltage before leakage exceeds 30 nA; ensures signal integrity on 12–15 V automotive data buses. |
| Cd | 0.31 pF (typ.) - Enables minimal signal distortion on >500 MHz NFC and USB 2.0 differential pairs. |
| VCL @ 16 A | 20 V (max.) - Clamps transients to safe levels for downstream 3.3 V or 5 V logic interfaces during IEC 61000-4-2 events. |
| Rdyn | 0.8 Ω (typ.) - Low dynamic impedance sustains effective clamping under fast-rising ESD pulses (tr ≤1 ns). |
| ESD Rating | ±10 kV contact / ±15 kV air - Meets IEC 61000-4-2 Level 4 for industrial and automotive end-equipment compliance. |
| Tj max | 150 °C - Supports operation in under-hood automotive environments and thermally dense PCB layouts. |
Pinout & Package
DFN1006-2 (SOD882) plastic leadless package: 1.0 mm × 0.6 mm × 0.48 mm body, 0.65 mm pitch, side-wettable flanks for AOI-compatible reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of diode 1 | Forms one half of symmetrical bidirectional clamp; connects to protected line in series with ground return path. |
| 2 (K2) | Cathode of diode 2 | Completes bidirectional path; both cathodes tied internally to enable equal clamping for positive and negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Enables protection of AC-coupled or floating signal lines (e.g., NFC antennas) without DC biasing requirements. |
| Snap-back dynamic behavior | Reduces clamping voltage by >30% versus standard TVS diodes under 100 ns TLP pulses, minimizing stress on IC I/O cells. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD robustness-supports ASIL-B system integration. |
| Ultra-small footprint | 0.6 mm² area allows placement adjacent to RF connectors without compromising 50 Ω impedance matching on high-frequency traces. |
Applications
| NFC Antenna Interface | USB 2.0 Data Lines |
|---|---|
Use Scenario: Protects 13.56 MHz NFC antenna feedline from ESD during user contact with smartphone or reader housing.

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 | Unidirectional configuration; 5.5 V VRWM; 0.6 pF Cd; SOIC-8 package (3.9 mm × 4.9 mm) | Requires separate devices per signal line; unsuitable for bidirectional AC signals like NFC; larger footprint limits high-density routing. | Select only when unidirectional protection suffices and board space permits larger package. |
| Vishay VEML6030X01 | Not applicable - VEML6030X01 is an ambient light sensor, not an ESD diode; invalid substitution. | N/A - incorrect device category; no functional equivalence. | Avoid: misidentified part; no ESD protection capability. |
Compared with NUP4105MR6T1G, PESD18VF1BBL-Q offers true bidirectional clamping, 3× lower capacitance, and 75% smaller footprint-critical for RF-sensitive and space-constrained automotive interfaces. The Vishay part is not a valid alternative.

FAQ
What is the maximum clamping voltage of PESD18VF1BBL-Q under IEC 61000-4-2 stress?
The device clamps to a maximum of 20 V at 16 A Transmission Line Pulse (TLP) current, measured with 100 ns pulse width and 1 ns rise time. This value is verified per IEC 61000-4-2 test conditions and ensures safe operation for 3.3 V and 5 V interface ICs downstream.
Can PESD18VF1BBL-Q be used on DC-biased signal lines?
Yes-it supports DC bias up to 18 V (VRWM), making it suitable for lines with static common-mode voltage such as automotive LIN bus or sensor analog outputs. Reverse leakage remains below 30 nA at full VRWM, preserving signal accuracy.
Does this diode require external biasing or control signals?
No-PESD18VF1BBL-Q is a passive, two-terminal device with no power or control pins. It operates autonomously: conducting only during overvoltage transients while presenting negligible loading (<0.31 pF, <30 nA) during normal operation.
How does the snap-back behavior affect circuit design?
Snap-back reduces clamping voltage dynamically during ESD events but requires careful PCB layout: keep trace inductance low and avoid DC current sources that could sustain conduction post-event. Layout guidelines mandate placement within 3 mm of the protected connector and direct grounding to minimize loop inductance.
