Product details
Overview
PESD18VF1BSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) package, designed to safeguard single high-speed signal lines against ±10 kV IEC 61000-4-2 contact discharge, with ultra-low 0.28 pF capacitance, 18 V reverse standoff voltage, and 16 V clamping voltage at 1 A peak pulse current. It serves in NFC antenna and high-speed data line protection where minimal signal distortion and bidirectional transient suppression are critical.
For engineers reviewing the PESD18VF1BSF datasheet, PESD18VF1BSF pinout, PESD18VF1BSF application, or PESD18VF1BSF equivalent, this page delivers verified electrical parameters, validated terminal roles, confirmed SMD footprint constraints, and real-world implementation guidance for ESD-critical RF and digital interfaces.
Technical Context
This device implements a dual-cathode, bidirectional TVS structure optimized for low-capacitance transient suppression on AC-coupled or bipolar signal paths. Its symmetrical V-I characteristics enable identical clamping behavior for both polarities, with dynamic resistance of 0.6 Ω under 5 A TLP stress.
It operates within −45 °C to +125 °C junction temperature range and maintains <30 nA reverse leakage at 18 V VRWM. The 0.28 pF typical capacitance at 1 MHz and 0 V bias ensures negligible loading on 13.56 MHz NFC and >1 Gbps data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Diode capacitance (Cd) | 0.28 pF typical at 1 MHz, 0 V - preserves signal integrity on 13.56 MHz NFC and USB 2.0+ lines |
| Reverse standoff voltage (VRWM) | 18 V - supports signal swings up to ±17 V without leakage-induced distortion |
| Clamping voltage (VCL) | 16 V at 1 A IPPM - limits transient overvoltage to safe levels for downstream 18 V-tolerant ICs |
| ESD rating | ±10 kV contact / ±15 kV air per IEC 61000-4-2 - meets industrial and portable electronics immunity requirements |
| Dynamic resistance (Rdyn) | 0.6 Ω at 5 A TLP - enables fast energy dissipation with minimal voltage overshoot during sub-ns transients |
| Reverse leakage (IRM) | 1 nA typical at 18 V - avoids DC path interference in high-impedance antenna or sensor circuits |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless 0.6 × 0.3 × 0.3 mm surface-mount package with two terminals on the bottom side, requiring precise reflow footprint per Figure 11 in the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of diode 1 | Forms one half of the bidirectional clamp; connects to protected line when used in standard orientation |
| 2 (K2) | Cathode of diode 2 | Completes symmetrical clamp structure; ties to ground plane to enable dual-polarity conduction |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Single-device solution for AC-coupled or differential lines without polarity constraints |
| Ultra-low 0.28 pF capacitance | Enables use on 13.56 MHz NFC antennas and >1 Gbps serial links without resonance or attenuation |
| 18 V VRWM with 16 V VCL | Provides 2 V design margin between operating voltage and clamping threshold for robust system-level protection |
| 0.6 Ω dynamic resistance | Reduces clamping voltage overshoot during fast-rising ESD events (<1 ns rise time) |
| −45 °C to +125 °C operation | Supports deployment in automotive infotainment front-end modules and industrial handheld readers |
Applications
| NFC Antenna Interface | USB 2.0 Data Lines |
|---|---|
Use Scenario: Protecting 13.56 MHz RFID/NFC antenna traces from user-hand ESD events during card tap or reader proximity. IC Role / Device Role / Timing Role: Bidirectional transient shunt placed directly at antenna connector, clamping ±8 kV pulses before reaching matching network or transceiver IC. Use Value: Maintains antenna Q-factor and read range by limiting capacitance to 0.28 pF while suppressing transients below 16 V. |
Use Scenario: Guarding D+ and D− lines in portable USB peripherals against ESD during cable insertion or handling. IC Role / Device Role / Timing Role: Low-capacitance clamp mounted adjacent to USB connector to minimize stub length and preserve signal edge integrity. Use Value: Prevents bit errors and link resets by clamping 1 A transients within 16 V while adding <0.3 pF load to 480 Mbps signaling. |
| HDMI/MIPI D-PHY Lanes | Industrial Sensor Interfaces |
Use Scenario: Shielding high-speed video or camera interface lanes from ESD in compact consumer displays and mobile cameras. IC Role / Device Role / Timing Role: Signal-line protector placed at board edge before serializer/deserializer IC, minimizing trace inductance to ground. Use Value: Enables compliance with IEC 61000-4-2 Level 4 without degrading 1.5 Gbps eye diagram opening. |
Use Scenario: Safeguarding analog or digital sensor outputs (e.g., pressure, temperature) exposed on equipment front panels. IC Role / Device Role / Timing Role: Ground-referenced bidirectional clamp on sensor output line, rated for continuous 18 V DC bias and ±10 kV surges. Use Value: Eliminates need for series resistors or RC filters, preserving millivolt-level signal resolution and response time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G | Lower VRWM (3.3 V), higher Cd (0.6 pF), same DFN1006-2 package | Suitable only for 3.3 V logic rails; unsuitable for 18 V NFC antenna bias | Select only if protecting low-voltage digital I/O with relaxed capacitance budget |
| TPD2E001DRYR | 0.8 pF Cd, 5 V VRWM, dual-channel configuration in DSBGA-6 | Requires PCB area for 6-pin package; not pin-compatible; higher parasitic loading | Prefer when multi-line protection is needed and layout space permits larger footprint |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, PESD18VF1BSF uniquely balances 18 V standoff, 0.28 pF capacitance, and DSN0603-2 size-making it the only option for space-constrained, high-voltage, high-frequency ESD protection such as NFC front-ends.

FAQ
What is the maximum recommended PCB trace length between PESD18VF1BSF and the protected signal line?
The datasheet mandates placement as close as possible to the input connector or antenna feed point. For optimal ESD performance, total trace length-including both signal and ground return paths-must be ≤2 mm. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot above the 16 V spec during fast transients.
Can PESD18VF1BSF be used to protect a 5 V USB 2.0 D+ line?
Yes, but with caution: its 18 V VRWM exceeds USB 2.0's 5.5 V max, ensuring no leakage or conduction during normal operation. However, its 16 V clamping voltage is higher than ideal for 5 V systems-designers should verify downstream ICs tolerate brief 16 V excursions during ESD events, or add secondary local clamping if required.
Does PESD18VF1BSF require a dedicated ground plane connection?
Yes. The device relies on a low-inductance, solid ground plane beneath its terminals. The datasheet specifies using ground vias near the cathode pads and minimizing the ground loop area. Without a proper ground return path, clamping effectiveness drops significantly-measured VCL can exceed 25 V under IEC 61000-4-2 stress.
Is PESD18VF1BSF compliant with automotive AEC-Q200?
No. The datasheet explicitly states this part is not automotive qualified. It lacks AEC-Q200 stress testing, and its qualification scope covers industrial and consumer applications only. For automotive infotainment or telematics, engineers must select an AEC-Q200–qualified alternative such as Nexperia's PESDxL5UF series.
