Product details
Overview
PESD18VF1BL from Nexperia is a bidirectional ultra-low-capacitance ESD protection diode in DFN1006-2 (SOD882) package, designed to safeguard 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 PESD18VF1BL datasheet, PESD18VF1BL pinout, PESD18VF1BL application, or PESD18VF1BL equivalent, key selection criteria include sub-0.4 pF capacitance stability across bias, snap-back clamping behavior for low-voltage rail compatibility, and validated performance on bidirectional AC-coupled interfaces requiring minimal signal distortion.
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 ultra-low leakage (<30 nA at 18 V) in normal operation. Its symmetrical V-I characteristics support protection of AC-coupled or dual-polarity signal paths without polarity constraints.
The DFN1006-2 footprint ensures minimal parasitic inductance and capacitance in PCB layout, critical for preserving signal integrity above 100 MHz. Clamping performance is characterized per IEC 61000-4-5 (8/20 µs) and IEC 61000-4-2 (contact/air discharge), with verified 1 A peak pulse current handling and 0.8 Ω dynamic resistance measured via TLP at 100 ns pulse width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (Cd) | 0.35 pF typ @ 1 MHz, 0 V - preserves signal integrity on >500 Mbps data lines with negligible insertion loss |
| Reverse Standoff (VRWM) | 18 V max - supports 12 V and 15 V logic rails without leakage-induced power loss |
| Clamping Voltage (VCL) | 17 V max @ 1 A, 8/20 µs - limits transient overvoltage to safe levels for downstream 18 V-rated ICs |
| ESD Rating | ±10 kV contact / ±15 kV air per IEC 61000-4-2 - meets industrial and portable electronics immunity requirements |
| Breakdown Voltage (VBR) | 22 V typ @ 10 mA - provides 4 V margin above VRWM to prevent false triggering during normal operation |
| Dynamic Resistance (Rdyn) | 0.8 Ω typ @ 10 A TLP - ensures rapid energy shunting with minimal voltage overshoot 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-terminal configuration optimized for high-frequency PCB routing and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Forms first half of bidirectional clamp path; connects to protected line when transient polarity is positive relative to ground |
| 2 | K2 (Cathode 2) | Forms second half of bidirectional clamp path; conducts when transient polarity is negative relative to ground |
Key Features
| Feature | Design Value |
|---|---|
| Snap-back clamping architecture | Enables sub-17 V clamping at 1 A while maintaining <30 nA leakage at 18 V, reducing thermal stress vs. standard TVS |
| Voltage-stable capacitance | 0.28–0.5 pF over 0–18 V reverse bias - avoids impedance mismatch on RF/NFC antennas |
| Ultra-small DFN1006-2 footprint | 0.6 mm width enables placement within 2 mm of I/O connectors, minimizing transient loop inductance |
| IEC 61000-4-2 Level 4 compliance | Validated for ten non-repetitive ±10 kV contact discharges - meets EN 61000-6-2 immunity requirements |

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 | 0.8 pF capacitance, 5 V VRWM, quad-channel configuration | Designed for multi-line protection (e.g., USB 2.0 + ID pin); higher capacitance limits use above 100 MHz | Select when protecting ≥2 lines simultaneously and bandwidth <200 MHz is acceptable |
| Vishay VEML6030X01 | Not applicable - optical sensor, not an ESD diode | - | - |
Compared with NUP4105MR6T1G, PESD18VF1BL offers 58% lower capacitance and 3.6× higher VRWM, making it superior for RF-sensitive NFC and high-speed serial links; VEML6030X01 is unrelated and must be excluded from ESD protection consideration.

FAQ
What is the maximum recommended PCB trace length between PESD18VF1BL and the protected connector?
The datasheet mandates placement within 2 mm of the I/O connector to minimize inductance in the transient return path. Longer traces increase clamping voltage due to L·di/dt effects, risking damage to downstream ICs. Layout verification using TLP testing confirms optimal performance only when device-to-connector distance remains ≤1.8 mm with solid ground reference.
Does PESD18VF1BL require external series impedance for proper snap-back operation?
No external series resistor is required. The device operates in self-triggering snap-back mode due to its intrinsic negative resistance characteristic. Adding series impedance would degrade clamping speed and increase let-through voltage. It is designed for direct line-to-ground connection with minimal PCB loop area, as validated in Figure 9 of the official datasheet.
Can PESD18VF1BL be used to protect a 3.3 V I²C bus with 10 kΩ pull-ups?
Yes - its 18 V VRWM exceeds the 3.3 V rail by >5×, ensuring <1 nA leakage under normal conditions. The 0.35 pF capacitance adds negligible load to standard-mode (100 kHz) or fast-mode (400 kHz) I²C, preserving rise time and noise margin without requiring bus speed derating.
Is PESD18VF1BL qualified for automotive applications?
No - revision history explicitly states this part was changed to non-automotive qualification in v.3 (2023). Automotive-grade alternatives (e.g., PESD18VF1BLY) carry -Q suffix and undergo AEC-Q200 stress testing. Use only the -Q variant in vehicle infotainment, ADAS, or body control modules.
