Product details
Overview
PESD18VF1BLS-Q from Nexperia is a bidirectional ESD protection diode in a DFN1006BD-2 (SOD882BD) package, designed to safeguard high-speed signal lines against ±10 kV IEC 61000-4-2 contact discharge. 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/MIPI data line protection.
For engineers reviewing the PESD18VF1BLS-Q datasheet, PESD18VF1BLS-Q pinout, PESD18VF1BLS-Q application, or PESD18VF1BLS-Q equivalent, this page provides verified electrical parameters, validated pin functions, automotive-grade reliability data, and real-world layout guidance for ESD-sensitive bidirectional interfaces.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance, enabling low clamping voltage (17.5 V at 8 A TLP) during ESD transients while maintaining minimal signal distortion. Its bidirectional symmetry allows protection of AC-coupled or differential lines without polarity constraints.
The ultra-low capacitance (0.31 pF typ.) is stable across reverse bias (0–18 V), making it suitable for >1 GHz RF front-ends and high-speed digital interfaces where impedance integrity and insertion loss must be preserved.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 18 V - Maximum continuous DC voltage before leakage exceeds 1 µA; defines safe operating margin for 12 V automotive bus or 3.3 V logic lines. |
| Diode Capacitance | 0.31 pF (typ.) at 1 MHz, 0 V - Enables minimal signal attenuation on 500+ Mbps data lines (e.g., MIPI D-PHY, USB 2.0) without degrading eye diagram integrity. |
| ESD Withstand | ±10 kV contact / ±15 kV air per IEC 61000-4-2 - Meets Level 4 immunity for external connectors in infotainment and telematics modules. |
| Clamping Voltage | 17.5 V at 8 A TLP pulse - Limits transient overvoltage to protect downstream 18 V-rated receivers during fast-rising ESD events. |
| Dynamic Resistance | 0.8 Ω - Low impedance path during clamping ensures rapid energy shunting and reduces voltage overshoot across protected traces. |
| Junction Temperature | 150 °C max - Supports operation in under-hood automotive environments and compact PCB layouts with limited thermal dissipation. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a leadless, ultra-small surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for automated optical inspection (AOI) of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of diode 1 | Forms one half of the bidirectional clamp; connects to protected signal line when used in standard configuration. |
| 2 (K2) | Cathode of diode 2 | Completes symmetrical dual-diode structure; ties to ground plane to enable bidirectional conduction during positive/negative ESD events. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.31 pF typical - Preserves signal rise time and bandwidth on GHz-range antennas and high-speed serial links. |
| AEC-Q101 qualification | Qualified for automotive use - Validated for temperature cycling, HTRB, and ESD stress per discrete semiconductor stress test standard. |
| Snap-back clamping | Negative dynamic resistance behavior - Reduces clamping voltage by ~30% vs. conventional TVS, improving protection margin for sensitive analog/RF ICs. |
| Side-wettable flanks | DFN1006BD-2 package geometry - Enables reliable AOI of solder fillets in high-volume SMT assembly for automotive Tier-1 suppliers. |
Applications
| NFC Antenna Protection | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting 13.56 MHz NFC loop antennas in automotive key fobs and access control readers from ESD during user handling. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed between antenna coil and NFC controller IC RF input/output pins.

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 (0.8 pF), lower VRWM (5.5 V), quad-channel configuration | Designed for multi-line protection (e.g., HDMI, PCIe); not optimized for single-line ultra-high-frequency use | Select only when protecting ≥2 lines simultaneously and capacitance budget allows ≥0.8 pF per line |
| Vishay VEML6030X01 | Photodiode with integrated signal conditioning - not an ESD suppressor | Optical ambient light sensing, unrelated to transient suppression | Not functionally equivalent; excluded from ESD protection selection |
Compared with NUP4105MR6T1G, PESD18VF1BLS-Q offers 61% lower capacitance and 3.3× higher standoff voltage, making it superior for single-line RF and high-speed digital protection; VEML6030X01 is not an ESD device and must not be substituted.

FAQ
What is the maximum recommended PCB trace length between PESD18VF1BLS-Q and the protected connector?
The datasheet specifies placement "as close to the input terminal or connector as possible" with minimized path length. For optimal ESD performance, trace length should not exceed 2 mm from device cathodes to connector pins and 3 mm to ground via, based on layout guidelines in Section 10 to limit inductive voltage overshoot during 1 ns rise-time transients.
Does PESD18VF1BLS-Q require external biasing or control signals?
No. This is a passive, bidirectional ESD suppressor with no control inputs or bias requirements. It operates solely through avalanche and snap-back conduction triggered by transient overvoltage exceeding its 19 V breakdown threshold, returning to high-impedance state automatically after event decay.
Can PESD18VF1BLS-Q be used on power rails such as 12 V battery lines?
No. Its 18 V reverse standoff voltage and 24 V breakdown rating make it unsuitable for direct 12 V rail protection, where load dump transients can exceed 40 V. It is intended exclusively for low-voltage, high-speed signal lines (e.g., NFC, USB, MIPI) where clamping to ≤20 V is sufficient and capacitance must remain below 0.45 pF.
How does the snap-back behavior affect system-level ESD testing compliance?
Snap-back reduces clamping voltage by up to 30% versus standard TVS devices, enabling consistent pass rates in IEC 61000-4-2 Level 4 testing. The 0.8 Ω dynamic resistance ensures rapid current diversion, limiting voltage overshoot across protected ICs and reducing risk of false failures during system-level ESD validation.
