Product details
Overview
PESD18VF1BL-Q from Nexperia is a bidirectional ESD protection diode in DFN1006-2 (SOD882) package, designed to safeguard high-speed signal lines against ±10 kV IEC 61000-4-2 ESD events. It delivers ultra-low 0.35 pF capacitance, 18 V reverse standoff voltage, and 17 V clamping voltage at 1 A, enabling use in NFC antenna and USB 2.0/MIPI data line protection.
For engineers reviewing the PESD18VF1BL-Q datasheet, PESD18VF1BL-Q pinout, PESD18VF1BL-Q application, or PESD18VF1BL-Q equivalent, this device is selected for automotive-grade ESD hardening of low-capacitance, bidirectional signal paths where leakage (<30 nA), dynamic resistance (0.8 Ω), and AEC-Q101 qualification are critical design constraints.
Technical Context
This dual-cathode bidirectional TVS diode operates symmetrically across both polarities, with breakdown voltage ranging 19–24 V and clamping performance validated under 8/20 µs surge (IEC 61000-4-5) and 100 ns TLP pulses. Its capacitance remains stable below 0.5 pF up to 18 V reverse bias.
The device uses silicon PN junction architecture optimized for minimal parasitic capacitance and fast response (<1 ns rise time per IEC 61000-4-2), with cathodes on both terminals enabling direct series placement across a single differential or single-ended line referenced to ground.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 18 V - Maximum continuous operating voltage before conduction begins; defines safe signal swing range. |
| Diode Capacitance | 0.35 pF (typ.) at 1 MHz, 0 V - Enables <1% signal distortion on >1 GHz RF/data lines like NFC and MIPI D-PHY. |
| ESD Rating | ±10 kV contact / ±15 kV air (IEC 61000-4-2) - Meets automotive infotainment and ADAS interface immunity requirements. |
| Clamping Voltage | 17 V at 1 A, 8/20 µs - Limits transient overvoltage to protect downstream 1.8 V/3.3 V IC inputs without latch-up. |
| Dynamic Resistance | 0.8 Ω (typ.) - Ensures low-voltage overshoot during fast transients by minimizing IR drop across the protection path. |
| Junction Temperature | 150 °C max - Supports operation in under-hood automotive environments and thermally constrained mobile PCBs. |

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 | 3.3 V VRWM, 12 pF capacitance - higher clamping but significantly higher capacitance. | Targeted at lower-speed digital I/O (e.g., GPIO, buttons), not RF/high-speed data. | Select only when signal bandwidth <100 MHz and ESD threat is lower-energy (e.g., consumer handhelds). |
| TPD2E001DRYR | 5.5 V VRWM, 3.5 pF capacitance, integrated 2-channel array - larger footprint, higher parasitic capacitance. | Designed for dual-line protection (e.g., USB D+/D−), not single-line bidirectional use. | Choose when protecting two independent lines simultaneously and board space permits SO-8 or X2SON packages. |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, PESD18VF1BL-Q uniquely balances 18 V standoff, sub-0.4 pF capacitance, and AEC-Q101 compliance-making it the only option qualified for automotive NFC and >1 Gbps serial link protection without signal degradation.

FAQ
What is the maximum peak pulse current the PESD18VF1BL-Q can handle?
The device is rated for 1 A peak pulse current under 8/20 µs waveform per IEC 61000-4-5. This value reflects its ability to safely divert transient energy without failure, validated across temperature and lifetime stress tests. It is not intended for repetitive surge events beyond datasheet-defined limits.
Is PESD18VF1BL-Q unidirectional or bidirectional, and how does that affect circuit placement?
PESD18VF1BL-Q is bidirectional, with symmetrical clamping behavior due to dual-cathode configuration (K1 and K2). It must be placed across the protected line and ground-or between two signal points-with no polarity sensitivity, enabling use on AC-coupled or differential interfaces like NFC antennas without orientation concerns.
How does the 0.35 pF capacitance impact high-frequency signal integrity?
At 0.35 pF typical, the diode introduces negligible impedance above 100 MHz (Zc > 450 Ω at 1 GHz), avoiding attenuation or phase shift in NFC, USB 2.0, and MIPI D-PHY signals. Measured capacitance variation is <10% from 0–18 V bias, ensuring consistent RF performance across operating conditions.
Does the AEC-Q101 qualification cover all environmental stress tests required for under-hood automotive use?
Yes-AEC-Q101 qualification includes temperature cycling, high-temperature operating life, unbiased high-humidity accelerated stress testing, ESD (HBM/MM), and mechanical shock. The 150 °C max junction temperature and -55 °C to +150 °C ambient rating further validate suitability for engine bay and powertrain control module deployments.
